Version 6.6.3 released on 30 March, 2019
Welcome to Apprentice Alf’s blog
This blog is intended to help anyone looking for free and simple software for removing DRM from their Kindle ebooks, stripping DRM from their Adobe Digital Editions ebooks, getting rid of DRM from their Barnes and Noble ebooks, freeing their Kobo ebooks of DRM, or decrypting their Fictionwise eReader ebooks.
If you want to find out more about ebooks, DRM and why you will probably want to remove the DRM from your ebooks, see this post: Ebook Formats, DRM and You — A Guide for the Perplexed.
If you already know that you want to strip the DRM from your ebooks, you’ve found the right place.

Getting Help with the Tools
If you have any questions about the tools, ebooks, and DRM, check the FAQs at the GitHub repository:
https://github.com/apprenticeharper/DeDRM_tools/blob/master/FAQs.md
If you have any problems with the current tools, please ask for help in a comment on this post or open a new issue at the GitHub repository. If you are having a problem with an older version of the tools, please first update to the current version, and see if that solves your problem.
Before commenting here, please check the ReadMe file and the FAQs (see link above).
In any bug report or help request, please include:
- which tool was used
- which OS you are using
- where the ebook file came from (device or application)
- any error messages
- a log of the DRM-removal attempt (see the FAQs on how to get a log).
Anti-Piracy Notice
Please only use these tools for gaining full access to your own ebooks for archiving/conversion/convenience. De-drmed ebooks should not be uploaded to open servers, torrents, or other methods of mass distribution. No help will be given to people doing such things. Authors, retailers and publishers all need to make a living, so that they can continue to produce books for us to read. Don’t be a parasite.
Origin of the Tools
The tools for removing DRM from ePubs were originally posted at i♥cabbages’ blog. The tools for Kindle/Mobipocket were originally posted at The Dark Reverser’s blog.
They have since been improved by many people, but mostly some_updates, DiapDealer, Apprentice Alf, and Apprentice Harper. While there are many sites that redistribute these tools, the most up-to-date versions of the tools are currently released here.
Other Sources
Anyone trying to sell you ebook DRM removal tools for Adobe Adept ePub and PDFs, Barnes & Noble ePubs, Kindle ebooks, Kobo ebooks, or eReader ebooks has probably just repackaged (an earlier) version of the tools available here.
Help!
The tools worked fine for me for years. But now they (both the Mac-standalone or the Calibre-Plugin) do not longer work on Kindle azw.files.
Gives an error message in the log:
“Content:B07C9Z5LMM_EBOK:B07C9Z5LMM_EBOK.azw is neither a Kindle not a Mobipocket file.”
And its definitely a Kindle file, works with the Kindle App on the Mac.
Just to clarify one point: i did not input a kindle number. For the simple reason the Mac Kindle App doesn’t have one.
And I cannot remember if years ago when I installed the old version of the tools I configured a kindle number (where could it come from anyway).
If you are using Kindle4Mac 1.17, then there isn’t a problem. If you are using Kindle4Mac 1.24, then the book is using a newer form of DRM called KFX but can be dealt with via a plug-in. If you are using Kindle4Mac 1.25 or later, then you are totally SOL!
Now with K4M 1.17 my Kindle files are located at: ~/Library/Application Support/Kindle/My Kindle Content Don’t know if it is the same for K4M 1.24.
Thanks for your help. The files are .aws, not kfx – and kindle4mac 1.21
So it should work …
They’re KFX. The file name extension bears no relation to the internal file format for files downloaded by Kindle for Mac or PC
Kindle for Mac 1.18 through 1.24 are all KFX so you’ll need to get the KFX plug-in(s) for Calibre. Alternately, revert to K4M 1.17, that’s what I did.
Or you can disable downloads of KFX with Kindle for Mac 1.19 through 1.23. All the options explained here:
https://www.mobileread.com/forums/showthread.php?t=283371
Hopefully the issue will be resolved and the plug-in made capable of dealing with Kindle4Mac 1.25 or later because older versions are 32-bit and will soon be imcompatible with MacOS.
Or install Parallels and install Mojave or earlier as a Virtual Machine and continue to use K4M 1.17
Doable, but it’s going the long way around. I’d prefer a more direct and simpler solution.
Oh, just checked, the current version (1.26.1 or greater) is 64-Bit. OK, then I suggest the modification from mobile-read.
This results in a few crash-logs, but these pop up only after “Kindle for Mac” is used, when you quit it.
If you can live with that, they go away after some time, I have not seen the crash-error for a few weeks.
The modification has to be applied for each update, so the suggestion to turn of auto-update for Kindle is still advisable.
Basically you drill into the App package. For safety reason you can duplicate the App before trying this.
Kindle.App – Contents – MacOS – and set the renderer-test to non-executable. I used a NortonCommander like utility, but you can use the mentioned chmod on commandline, see the Link below, may need sudo ( Admin account and password ) to execute the chmod.
chmod -x /Applications/Kindle.app/Contents/MacOS/renderer-test
After this, test this with a few newly downloaded books, and try to DeDRM them. This newer version uses a new folder for each book under the “My Kindle Content” folder, where ever you have moved this.
Link to the old suggestion for turning off KFX download:
https://www.mobileread.com/forums/showthread.php?t=283371
As far as I read here on this blog, the similar modification does not work anymore for the current Windows version for some reason, but I am not sure about that, I cannot try it without Windows.
I tried running the chmod with the current version. I did not see any success in conversions.
Did you see the info at the link about getting it to work with the current version of Kindle for Mac? I believe it relies on updating from 1.23 or earlier. But I’m on Windows so I’m not sure. I just know that others have definitely been able to.
My guess is, you use Calibre. DeDRM happens on import into Calibre, not during conversion, just to be clear.
And the books should be downloaded NEW, after changing something in the installation.
Maybe it is some other problem (not finding the key?).
As usual, a log is needed.
I use both the Calibre Plugin and the Mac Standalone, but prefer to DeDRM one book at a time with the Standalone App, as the popup tells wether there was DRM or not (I live in Germany and a few great German publishers do not use DRM anymore) and I can look into the log which is easier to read then the Calibre Log (it is shorter, imho).
If you are up to it, start fresh and then give is a log, if it is not working, I suggest the following:
– create a new User
– download Calibre
– download DeDRM
– install DeDRM plugin to Calibre
– download Kindle for Mac
– apply the chmod modification
– Login to Kindle for Mac
– download 2-3 ebooks
– try to read them in Kindle for Mac, this must work for the DeDRM to work
– start Calibre and turn logging on
– Import the newly downloaded books to Calibre
– quit Calibre and note where the log is
– start Calibre again without logging
– try to open them there with the Calibre reader
If this does not work, there is a clear message the ebook (still) has DRM, when look into
the log, and give is log, someone might be able to help.
I started with a clean install of Calibre and the latest DeDRM. No luck.
As Ingo said, post a log if you want help figuring it out.
Using DeDRM for years, I now have a Problem removing the DRM ON some epub books.

Log says that the file is “neither an Adobe Adept nor a Barnes & Noble encrypted ePub.” Is that true? If there is some other type of DRM on an epub, then DeDRM will not work. If it’s a Kobo kepub, then import it into calibre with the Obok plugin.
Hi Laura
The Obok plugin is no help. The Book is a epub “Nach Ohio – Benedikt Meyer.epub”
If I’m reading this translated website correctly, the ebook doesn’t have “copy protection” (ie DRM) on it: https://tinyurl.com/yyeroe3z
When i open it in calibre it says DRM protected.
Interesting. Did you buy it from the website in the link I posted: https://www.buecher.de ? If not maybe the site you bought it from wasn’t selling it DRM-free.
Looking at xromad’s comment, are you sure it has DRM? If it has something besides Adobe, B&N, or Kobo DRM, then these tools won’t help.
Re: The Book is a epub “Nach Ohio – Benedikt Meyer.epub”
https://www.thalia.de/shop/home/artikeldetails/ID142450287.html
Thalia says, the ebook does not have DRM.
My fault. Wife told me know that the book is from the library and not from thalia.de.
Ah, that makes sense. You may want to get it from Bücher.de or thalia.de (whichever is less)
After following the instructions to install the Kindle PC plugin, I have a kindle book that I purchased directly from Amazon, and downloaded to my PC using the Kindle PC program. Whent I try to convert the file to a pdf, I get a message that the file is still DRM protected. Computer is Win 7 Pro 64 bit. Her is a copy of the log:

Briefly: Go to Kindle Preferences and turn off auto-updates. Delete the downloaded book from Kindle for PC (& calibre). Quit Kindle for PC.Download Kindle for PC 1.17 and install that instead. Download the book using Kindle for PC 1.17 and import into calibre.
You can also remove the old “Kindle and Mobipocket DeDRM” plugin. DeDRM replaced all the individual file type DeDRM plugins.
Thanks, Laura. I did remove the other plugins as you’ve suggested. Thanks.
Thanks, for the reply, Paul. After posting this comment, I did some additional research on the web and discovered the issue with versions 1.25+ of Kindle. I uninstalled Kindle, downloaded and installed version 1.24.3. After downloading the azw file in Kindle, I was able to successfully remove the DRM with the Calibre plugin. Unfortunately, after converting the file to pdf, the formatting of the file got all discombobulated, rendering the pdf useless for any purpose. I can’t imagine what the cure for that might be, but I doubt it’s related to the removal of DRM. Geez, all I really want to do is to print the stupid file!
PDF is probably the worst for converting from or to. Maybe try converting to RTF. Which should open in most word processing programs.
Thanks, Laura. Well, that was interesting. I converted to RTF, and opened the document in Word 2010. I got precisely the right number of pages, every one of them absolutely blank except for a page break.
What type of Kindle file are you converting from?
It’s an azw file, Laura. 33 page document and the file size is 6.3MB. Not a big deal, but there is a good sized photograph on every page. It’s more like a series of 33 Powerpoint slides, than a text-driven book.
AZW can be any Amazon file type. What is the file extension in calibre once the DRM is removed?
Sorry. As you can tell, I do almost nothing with Kindle files. Avoid them like the plague, for just this very reason. This particular eBook was not available for purchase in any other format. To answer your question, the file extension, per the file that has been saved in my Caliber Documents folder by the program, is az3.
If it’s mainly a series of images, I suggest you use the KindleUnpack plugin, which will extract the images (& html) from the azw3 file. You should be able to print the images easily.
Thanks, Paul. The pursuit of a solution is mostly academic at this point. My time and effort on this has already gone way beyond the actual need to pull this off. I just don’t like to get beat on things like this, but I’m ready to throw in the towel. I’ve reached out to the author to see if she could possibly send me a pdf of the eBook.
Typo……extension is azw3.
“Geez, all I really want to do is to print the stupid file!”
While DRM could prohibit printing a Kindle file, you should be able to print it after removing DRM be it from .
From your description it sounds like a comic, art-book or a manual, it may be that the problem is with the printing, depending on your printer setup. As 33 pages is not that much, try printing one page at a time. This might help if it is a problem with converting to color to black/white or scaling for the printer.
As you guessed, if DRM is removed, there is not a lot we can do to help here.
Thanks, Ingo. The problem isn’t with the printing, as the converted pdf file is a total mess when opened in Acrobat. The text is huge, photos are as well, and therefore pagination is all screwed up. When viewing the file in Acrobat it is completely unrecognizable before even thinking about printing it.
I second Paul’s suggestion of trying the Kindle Unpack plugin. I’d also recommend switching to the 64-bit version of calibre.
I’m reposting my question as it was never originally published. Are there any known issues between Windows 10, Kindle for PC and the latest versions of Calibre and the tools? I’m looking to get a new pc and I want to know what problems I may encounter before I make the change. Thank you.
This question?
No issues in particular with Windows 10. As for issues with Kindle for PC, see this post:
https://www.mobileread.com/forums/showthread.php?t=283371
Thanks Laura. So it sounds as if I’d need Kindle for PC 1.17 (which I currently use and would need to transfer). Do you know of any compatibility issues with Kindle 1.17 and Windows 10?
I’m sticking with K4PC 1.17 as long as I can, but 1.24 or earlier will work. No issues with 1.17 and Windows 10.
Help please:
Trying to De-DRM an ADE eBook (acsm -> epub). I’m using Linux and for the life of me cannot get ADE to work on there. As a workaround, I have now installed ADE on my Android phone. This way I could at least download the book I had paid for. I was hoping that I could now transfer the epub file to my computer and do the De-DRMing from there. Turns out I seem to need a ADE Key which the plugin will automatically find IF ADE is installed on the computer (it’s not!) Is there any way to find out my ADE Key and manually add it?
P.S.: I’ve already spent 4 evenings to try and get ADE to work on Linux (through wine). My current problem is that I apparently need to download ADE 4.5.0, but I can’t find any versions below 4.5.8 or so.
To avoid possibly getting newer Adobe DRM that can’t be removed, use ADE 2.0.1. Available here: https://www.adobe.com/support/digitaleditions/downloads.html
Use ADE 2.0.1. Later version might use a newer DRM system which can’t be removed by the tools.
Thanks, I have now solved the problem in a very different way that for legal reasons I can’t go into. If in the future this arises, I will use your advice. Anyway: thank you and Laura for keeping up the good work!
I’m trying to back up a pair of DRM-protected books purchased directly from the publisher to Calibre (vs 3.47.1 running on Windows 10) from my aging Kindle Paperwhite (5th gen, vs. 5.6.1.1). The Kindle is showing its age and I don’t want to lose these books when it gives up completely. I I followed your instructions (thanks for being so clear…much appreciated!) and the deDRM plugin shows up on the main Plugins popup as being installed. However, it doesn’t come up on the list of “user plugins” that are available to install. Not sure what my next step should be; nothing changes when I try to load the book file from the Kindle and open in Calbre. Still getting the DRM protected message. Thanks for any help you can offer.
Have you entered your Kindle’s serial number into the DeDRM plugin’s customization?
Thank you so much, Laura! I hadn’t done this but it was exactly the ticket! I am now able to open these books in Calibre. Thank you, thank you!
The Barnes & Noble Nook DeDRM tool does not appear to be working any longer as far as retrieving new decryption keys. I’ve used the same key for about seven years, but was recently forced by B&N to change my password, which broke my key. I’ve tried to use the Calibre plug-in to retrieve my key. I keep getting the error “Could not retrieve key. Check username, password and internet connectivity and try again.” I’ve verified that I have the correct information and I have internet access. The tool just isn’t working. I’ve been trying for several days now with no luck. Has anyone else experienced a similar issue or does anyone know anything about this? Thanks.
Yes, the key retrieval stopped working when B&N cut off their old Nook apps. I was forced to change my password a couple times in the past few months, but luckily my key remained the same. The only way I know to get the key now is from a rooted Nook device or a rooted Android device with the Nook app. This issue at GitHub has discussion on the process (read through the whole thread as things were slightly different in some cases):

Thank you for the tools. Very helpful.
Here is one of my book and I am trying to deal with it.
Can you help me to fix the problem?
Thank you

Kindle for Mac and DeDRM need to be on the same machine and user.
Calibre version 4 is being worked on. It’s going to be making some big changes. Over at Mobileread is a thread on the beta that’s being tested. Can anyone who knows how to code plugins for Calibre please download the beta and text it with the DeDRM plugin and make sure it works and fix what needs fixing? This is one plugin I’m sure we don’t want to break when Calibre 4 is released. Thanks.
Downloaded Mac version 3.99.5 from today, put it in /Apps as Calibre 2, imported 8 ebooks, Kindle and EPub, all worked and opened without a problem.
All had DRM, and would not have opened in Calibre Viewer.
This is on a working Calibre installation, so nothing was changed, it found the plugins (DeDRM and others) and the settings, so imho currently nothing to fix there,
But why did you not do it yourself?
I don’t know coding Calibre plugins well enough to fix anything that may be wrong. I’ve not had a chance to test the Calibre beta. One thing that also needs testing is the options dialog screens. Thanks for testing. I plan on testing later this week, but I’ve not been able to just yet.
Ingo, I’m guessing this version 3.99.5 is a Beta? The reason is because my Calibre install is telling me there is a new version available but it says it is version 3.48.0.
Yes, 3.99.5 is the latest calibre beta. Thread at MobileRead (link for betas at the bottom of first post):
https://www.mobileread.com/forums/showthread.php?t=322850
Yes, thats the beta, someone (Jon?) asked wether it worked with DeDRM, and I tested it.
It shows how good the programmer of Calibre is, all settings and plugins where there – although I did not test much, so cannot confirm except for EPub (from German shops Thalia and ebook.de with Adobe DRM) and Kindle. Did not test Kobo.
(A few minutes later). Yes, oBook Kobo DeDRM plugin continues to work. As expected after the test yesterday.
As Barnes and Nobles recently forced me to change my password, I have yet to test an older Yosemite installation (with VPN as I am living in Germany) but guess Barnes & Nobles is now gone for me, good riddance, Kobo is getting better, and except for the Kobo changes to some EPub (enhancements?) I can live with that, but am not too fond of it, ok but I also was never with Barnes & Nobles, so nothing has changed really. Except, that Kobo knows I am German and does not sell me certain books they offer in USA.
The problem with Barnes & Nobles for me, is, I found a free book and bought it, but after the password change, my old Barnes & Nobles App “Nook for Mac” does not start anymore. So while DeDRM might still work, the problem is the download. Some have a solution with Android, but it is from the description a near hack to get to the password, I am up to it, but currently have no real important books I need to DeDRM from B&N, the free one would be nice to have – and might even be without DRM.
FYI, you can also download regular epubs from the Kobo website, instead of the kepubs you get from Kobo desktop.
Oh, thanks, did not see that, so that is new to me, that is really helpful.
You do great work here!
I returned an ebook that I purchased from Amazon. It was very easy to do, but I’m curious about how Amazon goes about taking the book back. Do they have access to the Kindle content on your computer??
While this is neither here not there, they sync Kindle for PC/Mac like they do your Kindle devices, if you have a working Internet connection. Books I give back – be it wrong purchases or Kindle Unlimited/Prime whatever lent are deleted with the next use of the Kindle or Kindle for PC/Mac (I do not have a Fire tablet, but guess it is the same there).
Thanks for that. It looks like anything I open with Kindle for PC winds up on their website as a list of my digital content. I don’t usually use it, but sometimes a book I open on Calibre defers to K for PC because of format AZW3, for example.I just deleted “my Kindle content” and all digital content on their website.
Wow, that’s drastic. I hope you have good DRM-free backups.
Just to be clear, it is not a bug, it is a feature.
They will also be deleted from your Kindle devices and Apps, as soon as they connect to internet, if I guess right…
And the ebooks you deleted are now gone without DeDRM backups, so why do it?
As long as you have a working Amazon account, you could have downloaded the books again, they know what you bought or lent anyway, deleting them does not change that.
Also, they still know what you read with the Kindle and Kindle Apps, as soon as you use them with a working internet.
As soon as you log out of your Amazon account on your Kindle, Kindle ebooks with DRM will stop working.
Only changing the setting to flight-mode (WLAN off) will help.
If you care REALLY about privacy, bought ebooks are not for you.
We live in a post-privacy world, so you have traded privacy for convenience.
I have around 4000 books without DRM in my Calibre folder. I’ll have enough to read! Thanks for the heads up.
You also won’t get any updates or corrections to those books either.
“You also won’t get any updates or corrections to those books either.”
That’s certainly true (and fair).
But I can’t imagine this to be an issue – I never got any update or correction when I bought a printed book 😉
I’ve definitely gotten updates for Amazon ebooks.
Is there a moderator who will please delete my stupid posts? Especially the last one!
I’m really hoping someone can help me. TL;DR: downloaded library kindle book will expire before I need it, went to buy it on kindle and they aren’t selling it. I need to remove the DRM to use the book.
I can’t believe this!! I borrowed a Kindle book from my local library about IDing edible mushrooms because I’m going on a trip. I had a hold on the book, and when it was ready I grabbed it – but it will expire before my trip, and there are already holds on it so I can’t just renew. It’s a large book with lots of pictures (46mb file). I know deDrm isn’t made to do borrowed books – I found that out after converting a few times (It took hours) and then the file wouldn’t open on the other device I have registered to a different email. I downloaded the file into the Kindle for PC – v 1.24.3. I have the deDrm tools installed on Calibre. The file opens as a mobi, I don’t get any error when I try to convert it to epub(although the formatting doesn’t convert well, so I keeping it a mobi is fine). I realize there is a problem being it is a borrowed book, so I went to Amazon to just purchase it for $15… and Amazon has this error: “Item Under Review This book is currently unavailable because there are significant quality issues with the source file supplied by the publisher.” The file looks fine on my device and on the PC. I really need a copy for my trip. Can anyone help me out?
Is it available in print from somewhere else? If you need it that bad, see if there is a used paperback copy somewhere.
Oh, what is the title?
Title is “Mushrooms of the Midwest”
PJ, you should be able to get it from Google Play, Apple Books, B&N Nook, or Kobo as an ebook, according to the publisher, University of Illinois Press, or as a paperback (new or used) from Amazon.
I’m seeing it on Google Play for $10.49. You could try a sample before buying. But we’re not going to help with a library book.
“Mushrooms of the Midwest” checking from Germany (!), not sure about the US, but it is available for Eur 11,10 from
play.google.com so maybe other also have it (ebook.de dos not).
1 Eur is 1.10 Us$ today, so maybe Us$ 12 or a little more.
Listed as DRM protected. As I have bought a few ebooks from them, this the normal Adobe DRM, or was, the last time I bought from them. It is not said, wether you get the EPub, or a PDF or I overlooked it.
Cannot remember how it works, but I have an Adobe ID for quite some time and if you have your credentials on hand, you can enter them somewhere, so Google play EPubs work with the older Adobe DRM for me.
A sample is available.
The US Google Play listing says it is “original pages” under the book details. That means PDF. An EPUB would say something about reflowing text.
Buying it somewhere else as an EPub with Adobe DRM and stripping DRM might be solution. It should then be able to convert, or maybe not (to it sounds like an embedded PDF, if it has lots of pictures). EPub without DRM is a ZIP-File wich can be opened and looked into, it is a variant of html, css and pictures, not that hard to understand if you have basic html knowledge and/or a programming language you know.
Being that quite a few books are not available due to quality issues for a short or even longer time, it might also not be available as an epub.
BUT: “The file opens as a mobi” as you said, it does so in Calibre?
When you do not have any hard DRM on the file – some library ebooks might not have DRM, or soft DRM which is different, not identifying as a lent books to DeDRM, so DeDRM is working.
As you said it “expires” I do not how that would work without DRM, as I have not lend an ebook from a library (yet).
Ethical issues not withstanding, if the ebook really opens with the Calibre viewer and is useable, you can copy the Calibre Mobi-file to your Kindle and use it without having it expiring.
In my view you have tried everything, so while it is still wrong …
And it is not like you could easily look into the DeDRM code and change the statement for lent ebooks so it does not work anymore, which would be unethical too.
I should’ve been more clear. When I open the azw in Calibre, it appears as a Mobi. It looks good in Calibre’s viewer, but I can’t open it in the kindle app on a device not connected to my account. I did manage to look into the DeDrm code and it still does not take care of it. I also downloaded kindle for PC 1.17. I opened the file in a trial DRM software after also looking into the code and it quickly saved it as an azw3 with an “ok” status, but I cannot open any azw3 files in the kindle app. If I attempt to convert it to epub in Calibre, it takes about 3 hours and it’s very messed up 😦
As stated before, if you are able to open and read the file in Calibre, DeDRM has worked (or there was no DRM in the first place).
Every other problem you have after that is a problem of the file (take it up with the publisher) or Calibre conversion.
Conversion problems, as per your words: “it works, but looks pretty messed up” are outside the scope of this website, either the Bugtracker of Calibre (I have filed a bug or two there it is working) or the forum of Calibre or Mobileread might help.
(Sorry for some left out words in the last few comments, I tend not to proofread, my bad).
With Amazon not selling this file currently, it looks to me, as if at least the Kindle version had serious problems and someone took the time to report them.
Given that it is a book about mushrooms and your life may depend on it, I would not trust the publishers, if they cannot even put out a simple correct ebook. It is a few years old, so may not even be a new problem.
Wether the EPub is any better, is for you to find out.
I think I’d stick with a print copy on this type of book myself!
Thank you. I can read the library book file on the kindle fine. It has a lot of formatting – it’s in columns and has tons of pictures. I had a feeling it wouldn’t convert well to a different format, I just hoped it would read as well as the original after stripping the DRM. Ingo, you make a good point about reliability of content!
Initially, Calibre would throw an error when I tried to convert, so I think the plugin is working (even if the converted files are messy) correct? Does Calibre strip the drm from the original file once it’s in the Calibre folder? I’m very clumsy with this, I just have a large non drm Calibre library of normal, minimally formatted books to swap between ePub and mobi. I did strip drm from an Overdrive book years ago, but that doesn’t even exist anymore. Normally I just let the library books expire. I’ll check on google play. Thank you.
The Calibre mobi file opens the Kindle app, but then isn’t there. The drm-removed .azw3 file opens the app and immediately says “incompatible document type” and kindle for iPad then closes. Calibre’s reader opens azw3 files, but the app doesn’t recognize them. Is azw3 not an acceptable extension? The original file is .azw, but never stays that way after drm removal.
AZW is a generic extension Kindle for PC/Mac uses for any Amazon format. What you see after DRM removal is the extension for the specific Amazon format. I think Kindle for iPad uses different formats than the other Kindle apps. But I’m not sure as I’ve never bothered with Kindle for iPad.
I m on Windows 7 and I am trying to remove the DRM from some Kindle books with Calibre as I have always done, but I am being stonewalled, even after down degrading the recent PC Kindle app to a previous version( 1,24) which is supposed to download Kindle books in the previous AZW format and and not the KFX.
I installed the latest Calibre version ( 3.48) but still it doesn’t work.
When I try to (re)install the DeDRM 6.6 plugin. in Caliber I get an error message
Quote ERROR: Unhandled exception: InvalidPlugin:The plugin in u’C:\Users\vivona\Downloads\New folder\DeDRM_tools_6.6.3.zip’ is invalid. It does not contain a top-level init.py fileUnquote.
The decryption and PDF conversion do work with the Epubor Ultimate but it is a trial version and we only get a uselss skeleton of the book . To get the complete PDF version we have to buy the software.
I wonder why Calibre doesn’t work as it did before,It always returns the messages that the book is DRM covered.
Can you help, please
Thanks
Ittiandro
Kindle for PC version 1.24 will still download KFX format (and it still uses the same AZW extension) unless you make a change to one of its files. See this post at MobileRead:
https://www.mobileread.com/forums/showthread.php?t=283371
You’re trying to load the whole archive instead of just the plugin. Unzip DeDRM_tools_6.6.3.zip. Look in the DeDRM calibre plugin folder for the zip file to load into calibre.
Don’t waste money on Epubor. It cannot do anything these free tools can’t do.
Actually, Laura, back in June 2015 I had success using either Epubor or Epubsoft to remove DRM on three Nook books that DeDRM failed to do so. It was that experience caused me to swear off Barnes & Noble ebooks for good. I would not have had to use the commercial software if Amazon had the books in Mobi format or if the then current DeDRM version had worked.
You are absoluteky right, Kindle v.1.24 still downloads KFX, bu I had found this info on the Internet. In fact, I was able to solve the problem by fiuther degrading to v. 1.17 and it works beautifully on Calibre. thanks for your hint.
Ittiandro
I never had any problems removing B&N DRM with DeDRM back then. But I no longer buy ebooks from them either.
Just installed the latest public macOS 10.15 beta in a Fusion VM. Although I did figure out how to enable unsigned apps (sudo spctl –master-disable will do the magic), I was still unable to start the DeDRM 6.6.3 application, even when right clicking to open (Message: The application “DeDRM” can’t be opened). The ReadMe states that this is a 64bit app, any ideas why it would not launch?
There is still some 32-bit code in the DeDRM standalone app. See this thread on GitHub: https://github.com/apprenticeharper/DeDRM_tools/issues/898
Does the Calibre plugin work on Catalina?
Yes. The plugin works.
Thank you. That’s good news.
Using a MacBook Air. Obtained the ebook using Kindle for Mac.

Yes, I can open the book.
I have ADE 4.5!!!!!! What can I do?
I uninstalled ADE 4.5 and installed ADE 2.0. Then I authorized my adobe id, but still Calibre do not remove the DRM
And you can read the book with ADE 2.0.1 authorized with your Adobe ID?
Yes, I can do.
Yes, I can do. Sorry for the delay, but I forgot to mark the mail request.
Try deauthorizing and reauthorizing ADE. Instructions are here (scroll down past the Mac instructions to see the Windows section):
https://helpx.adobe.com/digital-editions/kb/activation-errors-adobe-digital-editions.html
Be very, very careful if you modify the Windows registry.
I just installed 6.6.3 and cannot remove the DRM. I downloaded the book I purchased from Amazon using the “Transfer by USB” option. I then drag it over the DeDRM app icon and the process begins, but then I get a message that there was an error. I’m using MacOS Mojave 10.14.6. I don’t use Kindle for Mac, I just like to read the books in iBooks on my iPad or iPhone. I’ve input my Kindle serial number into the app (it’s an old keyboard Kindle from 2012).
What’s the error? Better yet, post an error log
Pardon my ignorance, but how do I find the log? I just get a pop-up that there was an error or a warning opening one eBook and that’s it. I looked at the menus with the app open but don’t find a reference to the log.
The DeDRM app should leave a log file called “DeDRM.log” on your Desktop when it finishes. It’s a simple text file. Open it, copy the contents, then paste it here.
Here is the log:

Found k4Mac kinf2011 file: /Users/rolandoG4/Library/Application Support/Kindle/storage/.kinf2011
Couldn’t decrypt file.
Could not retrieve Kindle for Mac/PC key.
There was an error with 1 ebook:
The Great Passage.azw couldn’t be decrypted.
The pertinent info is: ImportError: No module named Crypto.Cipher.
See here from Alf FAQ for workaround: https://github.com/apprenticeharper/DeDRM_tools/blob/master/FAQs.md#the-application-opens-but-always-gives-an-error-in-the-log-importerror-no-module-named-cryptocipher
The pertinent line is: ImportError: No module named Crypto.Cipher
If you’re comfortable opening a Terminal window, this workaround should help (it’s from Alf’s FAQ on GitHub; I posted a link but it seems to have been caught in moderation, so I’m posting the actual commands here):
sudo python -m pip install pycrypto
if error “No module named pip”, type:
sudo easy_install pip
try again: sudo python -m pip install pycrypto
if installation fails because “C compiler cannot create executables” and pop-up window asks you to install Command Line Tools for XCode, agree by clicking “Continue”
try again: sudo python -m pip install pycrypto
If after installing pycrypto decryption still fails with something about pylzma in error log, try:
sudo python -m pip install pylzma
I noticed that the log says it couldn’t find the Kindle for Mac/PC key. I don’t know how that figures into the process. I’ve always downloaded file from Amazon with the option ‘Transfer via USB’ then opened the file in iBooks. I’ve entered my Kindle serial number in DeDRM. If the problem is not having the Kindle for Mac/PC key, how do I find that key and how do I provide it to DeDRM?
If you have it in iBooks, why not just put that copy into Calibre? That’s what I did with all the ePubs in iBooks using iBookCopy.app
Sorry, xromad, I didn’t make myself clear. I do put all the books into Calibre, I just remove encryption before I do that, rather than doing it within Calibre. I didn’t try doing the decryption through Calibre with this new problem because I figured the drag and drop was a simpler process and it it didn’t work there, it probably wouldn’t work within Calibre either,
The Mac DeDRM standalone is known to not work properly all the time. The recommendation is to use the Calibre plug-in and let Calibre remove DRM on import. IIRC, iBookCopy MAY do the job first but since I just put its output into Calibre, I can’t confirm it.
Thanks, xromad. I’ll try installing the Calibre plugin and see if that works.
Remember to put the Kindle serial number into the DeDRM plug-in settings.
Will do, thanks.
I use the Mac standalone app all the time without problem.
The key error in Roland’s log is: ImportError: No module named Crypto.Cipher
A workaround for this on Alf’s FAQ on GitHub, is to open a Terminal window and input:
sudo python -m pip install pycrypto
if error “No module named pip”, type:
sudo easy_install pip
try again: sudo python -m pip install pycrypto
if installation fails because “C compiler cannot create executables” and pop-up window asks you to install Command Line Tools for XCode, agree by clicking “Continue”
try again: sudo python -m pip install pycrypto
If after installing pycrypto decryption still fails with something about pylzma in error log, try:
sudo python -m pip install pylzma
(I tried to post a link, but it seems to have been caught in moderation)
Thank you so much for the thought you put into this, Zola, but I don’t have the background to have enough confidence to work in the terminal this much. But on the bright side, I did install the Calibre plugin and DeDRM is successfully decrypting there. So I’ll modify my workflow to just import the books into Calibre for decrypting and then just import to iBooks from the Calibre library. I have to go into Calibre anyway to convert to epub, so no extra work, really. Thanks again.
Thanks for the suggestion, xromad, I installed the Calibre plugin and it’s removing the DRM fine there. I collect all my books in Calibre anyway and use that to convert the Kindle files to epub, so no extra work. I then go to Apple Books and add the book from the Calibre library. Apple Books is syncing fine between devices now, so the book shows up on my iPad and iPhone without any other action needed. And if anyone is wondering why I’m going through this, I just like the Apple Books interface better than Kindle for iPad/iPhone, and the Kindle versions are usually less expensive than Apple’s. Thanks again.
I dumped iBooks after an update totally screwed up my sort by author/series of the 1000+ books on my iPad. iBooks limited sort options require manually sorting your library which is very labor-intensive when you have large libraries. I now use MapleRead SE on my iPads for my almost 2K books.
It is probably not the normal DeDRM error, but a typical macOS safety feature which prevents download from unknown sources to run. There are a few things to allow this, I think both may be needed:
Apple-Menu – System Preferences – Safety – Security & Privacy – Privacy,
select “Full Disk Access” in the left list, klick the lock and input your Admin credentials, select the DeDRM.App in the right list and set (x) to allow full disk access.
Klick the lock again to secure that setting, quit System Settings.
Test again.
(the following is another way to this but according to Google should do the same)
– Control-click the app icon, then choose Open from the shortcut menu.
– Click Open
If all still fails, the log is needed.
Hi Ingo, I did as you suggested and gave DeDRM full disk access, but still got the error message. Here is the log from that event, in case it is any different from the log for the error prior to granting full disk access:

Ingo, which MacOS version are you citing? None of my versions show a “Safety” tab; “Security & Privacy” are just in the main “System Preferences” window.
Oh, sorry, my bad. First I started with my own translation ( in German the System Setting is “Sicherheit”), when I remembered I have “language switcher” and launched the System settings in English (although titles remained in German) and forgot to change that in the text. Sorry for the confusion.
General question concerning KFX from Amazon:
For some time now several bypasses have been discussed here / used succesfully using old Kindle-versions etc. Which seem to work somehow (haven’t figured it out yet, but have still to try some variants) – but they will expire as new OS-versions etc. appear.
Is there any idea or people working on a solution to directly deal with KFX and deDRM it like any other format?
Or did everyone surrender to Amazons encrypting power?
A workaround for K4Mac 1.26.1 (which works on Catalina) has been reported on MobileRead: https://www.mobileread.com/forums/showpost.php?p=3819708&postcount=508
The latest changes to the DRM used on KFX have not been figured out yet. This is an all volunteer operation — so no idea if someone is working on it until (or if) they decide to share it.
To get KFX files which these tools can handle, you’ll need the older 32-bit Kindle for Mac/PC (versions 1.19 through 1.24). But for conversion, you’re probably better off sticking to the older (KF8/AZW3) format when possible. Those can be downloaded with the 64-bit Kindle for Mac 1.25 and later with the workaround Zola linked. Or from the Amazon website if you have an E-ink Kindle. PC users will be OK until Kindle for PC version 1.24 stops working (no imminent threat of 32-bit apps getting cut off), but right now version 1.17 is still fine.
Update to 4.1 fails in DeDRM plugin, so I attempted to update to 6.3.3 and got following error:

How do I fix this?
You are trying to add the tools archive (e.g. DeDRM_tools_6.5.3.zip) instead of the plugin. The tools archive is not the plugin. It is a collection of DRM removal tools which includes the plugin. You must unzip the archive, and install the calibre plugin (DeDRM_plugin.zip) from a folder called “DeDRM_calibre_plugin” in the unzipped archive.
Please report back whether the Calibre plugin works in Calibre 4.1. Thanks!
I successfully installed the DeDRM plugin and restarted Calibre. When attempting to Convert a KFX-ZIP to MOBI, I received the following error:

calibre.ebooks.DRMError: This book has DRM
DRM removal happens on import, not conversion. Try deleting your book then re-importing it. When you re-import, DRM removal should occur. After that, conversion should work.
Tried what you indicated and it didn’t work. Here is the debug file:

Try going back to Kindle for Mac version 1.23 or earlier.
Where can I download a copy of Kindle for Mac version 1.23
Download link for 1.23.1 plus instructions on getting Alf to work with K4Mac 1.26.1 (if you’re planning to upgrade to Catalina) here: https://www.mobileread.com/forums/showpost.php?p=3819708&postcount=508
Just wanted to share this with everyone interested:
I did a fresh install of macOS 10.15 (Catalina), Calibre 4.1. and DeDRM 6.6.3
The Calibre plugin works smoothly (at least with the PDFs for Adobe Digital Edition)
The DeDRM application is still 32bit as it has been reported before and will therefore not open on Catalina
There is an open issue on Github for this. If it takes longer to fix, it might make sense to add something to the DeDRM app readme, which currently states that the app is 64 bit
I used ADE (Adobe Digital Edition) 4.5.10, which is 64bit.
Here is the catch: If the media is delivered with ADE 4.5.10 using the hardened DRM, which is up to the vendor of the media to decide, it cannot be decrypted
There is a good chance (or maybe even guarantee) that the decrypt will still succeed using ADE 2.0.1 (32 bit) on 10.14 or older (e.g. in a VM), as ADE 2.0.1 does not support the hardened DRM
Bottom line: upgrading to Catalina may make it impossible to decrypt files protected with Adobe DRM, regardless of 64bit support of DeDRM. This would only change if someone finds a way to break Adobes hardened DRM
Yes, this has been a concern of mine as well. When Adobe first introduced hardened DRM, there was talk about 3 settings available to vendors: 1) no hardened DRM regardless of ADE version, 2) hardened DRM on ADE 3 or 4, but regular DRM on ADE 2, and 3) hardened DRM required, which means user must use ADE 3 or 4 and book will fail to download on ADE 2. However adoption of hardened DRM has been limited so far.
I’m getting a segmentation fault when I try to open calibre after updating and I think it’s related to the tools.

Segmentation fault
Apologies if this has nothing to do with the tools, but I’m stumped. My only guess is that I’m using an old version of the plugin and it’s incompatible with the latest calibre, but that leaves me with the question of how to update the plugins when I can’t get into calibre.
Uninstall latest calibre and go back to previous? Remove or disable DeDRM. Then try installing latest calbre and loading latest DeDRM. I’m using calibre 4.1 and DeDRM 6.6.3 without issue on Windows. Haven’t seen anyone else with Linux report problems here yet.
Tried that and it didn’t work. Every time I install the latest version the errors start with failing to initialize the plugin. I’d ask on the calibre forums but I already know they’ll refuse to respond because of the deDRM.
Thanks anyway.
In my opinion, asking for help with installing a plugin is very different to asking for detailed help in removing DRM from an ebook. Give the calibre forum on MobileRead a try. Just make it clear you’re asking for help with installation, not use.
Agree with Paul. There might be other plugins having similar problems too.
CARE by TEA/Vivlio is now commercially used, not just by libraries. Would appreciate if that DRM mechanism could be DeDRM’d in the near future 🙂
There have been just a few posts about Catalina, and I wanted to add something and solicit additional feedback.
I had run into the Kindle >1.24 issues and followed the recommended tactic (turning off auto upgrade, deleting and installing 1.23.1 (under High Sierra) and all is working (running 6.6.1)
I have upgraded to Catalina and the conversion for adobe seems to be working fine, but of course Kindle does not work under Catalina. I saw that there has been a post (https://www.mobileread.com/forums/showpost.php?p=3819708&postcount=508) that Kindle for Mac 1.26 (version current in App Store) will work with Catalina, Kindle 1.26 and Tools 6.6.3 IF, as in my case apparently, things working with Kindle 1.23.1 before the upgrade.
I am of course leery of moving forward with any changes less things break, so I am looking for any confirmations as to success or failure, and recommendations as to whether I should upgrade from 6.6.1 to 6.6.3 before or after upgrading to Kindle 1.26.
In the past, I used Kindle to download the file, and then used calibre to add book from inside the Kindle directory on my Mac. Don’t know if this is what odamizu intended, and whether one needs to delete all old files, then close kindle, and then reopen, etc.
Anyone else have any experience with Catalina?
For the best chance of success, you need to update to 1.26 and confirm it’s working with Alf BEFORE updating to Catalina.
If you have already updated to Catalina while on 1.23.1, then the worse that will happen if you update to 1.26 is that it will continue to not work. However, if you’re lucky and there’s a kinf2011 key file leftover from when you were on High Sierra AND Amazon recognizes your device as the same on Catalina as it was on High Sierra, there’s a reasonable chance it will succeed.
It would probably be best to leave Alf at 6.6.1 while you try this. If it succeeds, it will probably be safe update to 6.63, but no guarantees.
Do NOT delete any old files in User > Library as that will almost guarantee failure. However, it is safe to remove individual ebooks from your Kindle Library while using Kindle for Mac. Just don’t delete files directly from any User > Library folders.
If that were the case, then what would be responsible for the plugin to begin working with Kindle 1.26? In other words, what would have generated the kinf2011 key file?
kinf2011 is part of Kindle for Mac 1.23.1. Alf needs kinf2011 to create dedrm.json, which unlocks your books.
1.26 does not use kinf2011. Instead it uses kinf2018, which Alf cannot handle (yet?).
So you either need kinf2011 or dedrm.json leftover from 1.23.1 AND because keys are device-specific, Amazon must recognize 1.26 as being on the same device as 1.23.1.
If kinf2011 or dedrm.json have been lost, or if Amazon treats 1.26 as being on a new device after upgrading to Catalina, Alf won’t work. This is why it’s best to get 1.26 working with Alf before upgrading to Catalina.
OK. I installed 1.26.1 and it recognizes the books already downloaded, I think. But when I right click in Kindle to download, and the app downloads, it does not seem to appear in the same directory as the rest of the books. Where should I look for the downloaded book using 1.26 and catalina?
Try:
Users > Home > Library > Containers > com.amazon.Kindle > Data > Library > My Kindle Content
– OR –
Users > Home > Library > Application Support > Kindle > My Kindle Content
oy…..
found that kindle 1.26 had moved directory. tried pointing back to old directory.
download produced the book there in azw format.
attempt to add resulted in adding in KFX-ZIP file, which is useless.
Be sure to look at the tips hidden in “spoiler” tags in the post at MobileRead:
https://www.mobileread.com/forums/showpost.php?p=3819708&postcount=508
Yes, the chmod command, but apparently I had done something else out of order. Removed the kfx-zip, removed the book from the kindle local lib, upgraded to 6.6.3 (already had both kfx plugins at current version), restarted calibre, and…..
JOY!
so, I was able to upgrade to catalina while at Kindle 1.23.1 ***, install Kindle 1.26.1, point kindle 1.26.1 to the 1.23.1 store, download the book using context menu in kindle 1.26.1, add the book to calibre, and have the book appear as an azw3, convertible to epub.
Oh frabjous day!
this demonstrates that one need not have upgraded from 1.23.1 to 1.26 before upgrading to catalina (though I did have 1.23.1` working before upgrading. Not sure what all the intricacies might be, but my sequence did apparently result in everything working (HUGE sigh of relief).
Thanks.
*** Note: I had kindle set to auto upgrade, so had had to delete the upgraded kindle and return to 1.23.1. That meant I had two stores on my computer, as the “new” kindle created a new store, but when I reinstalled 1.23.1 it went back to using the old location. I pointed the newly installed kindle back to the 1.23.1 store.
Ah, good to know. But you do need to having 1.23 working with the DeDRM plugin before upgrading to Catalina. And safest to also get 1.26 working beforehand because you can’t go back to 1.23 after.
Excellent! Can you explain how you “point kindle 1.26.1 to the 1.23.1 store”?
Since decryption keys are device specific, knowing how to do this will increase the likelihood of 1.26.1 continuing to work if you have a valid kinf2011 or dedrm.json.
To change where Kindle points:
Open Kindle 1.26.1.
From the menu bar go Kindle -> Preferences
Under “Content Folder” click on “Change” and select Library/Application Support/Kindle/My Kindle Content instead of Library/Containers/com.Amazon.Kindle/Data/Library/Application Support/My Kindle Content
( the latter being where 1.25 apparently set up the content folder )
BTW, the Preferences panel also shows when the device was registered – in my case, in 2013 🙂 so it made the “leap”
There is a checkup selection under help, and I ran that and kindle’s internals say it is healthy,
BUT I have noticed that Kindle 1.26.1 crashes on exit now, though it appears to save all settings before doing so, lol.. I don’t know if this is in any way related to anything I have done, and frankly at this point don’t care because the crashing doesn;t seem to impact any functionality.
Thanks! This is very helpful in case things go awry through the upgrade process.
As for the crash, that is an unfortunate side-effect of using chmod -x.
