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.
The Tools
To get started on removing DRM from your ebooks, just download the tools archive from the link below. Unzip the archive, and start reading.
The latest release can be found at the top of this page:
https://github.com/apprenticeharper/DeDRM_tools/releases
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.
Calibre is currently beta testing a Python 3 version. Python 2 code is going away. Will the DeDRM plugin be fixed to work with this new version of Calibre? I would hate to have a new Calibre where I cannot remove the DRM.
The thread at Mobilread on the Calibre beta for the new Python 3 version can be found at https://www.mobileread.com/forums/showthread.php?t=325721
I hope someone will work on making sure the DeDRM plugin will continue to work with Calibre.
GitHub repository is here for anyone with the desire and skill to work on it:

Hello, i’ve tried to “reDRM” some ebooks from Kindle for Windows…
But the Plugin “DeDRM_Windows_Application won’t work… Calibre says the following things to me 🙂
I’ve also tried the “DeDRM Calibre Plugin”, but the “kindle for pc/mac” tell me, that i need a key… i don’t know, what he want from me.. help pleeease 🙂
calibre, version 4.6.0

hmmmm.. okay… maybe the problem is, that i had lend the book…
Yes, these tools are intended for purchased books.
The DeDRM Windows App is a stand-alone program, not a calibre plugin.
DeDRM will automatically find the key for Kindle for PC as long as Kindle for PC and calibre/DeDRM are on the same PC and Windows user.
What about when transferring Calibre from one computer to a new one? Please advise as to be steps for this process. Thank you.
I think I figured it out! I updated Calibre on my old pc to the latest version. Then I exported all Calibre data to a thumb drive. I installed Calibre on the new computer and imported the the file from the thumb drive. I installed the plugin tools and restarted. It looks as if my whole library and customized plugins with keys took effect on the new device.
Each installation of Kindle for PC has its own unique key, but again DeDRM should find it if it’s on the same machine and user.
Is there a DeDRM app for Chrome?
No, Windows, Mac, and the calibre plugin (and calibre is available for Windows, Mac, and Linux.)
I have a MacBook Air. I have the latest Calibre. I have downloaded the DeDRM tool and the KFR Input plugin. I have also customized the plugin. When I add a book I have purchased to Calibre…it doesn’t DeDRM it. It just gives me an error that says it cannot convert the KFX book. Please help!
There’s an issue with DeDRM dealing with KFX files starting with calibre 4.6. Either disable the download of KFX files or try going back to calibre 4.5. See method 2 or 4 at this post:
https://www.mobileread.com/forums/showthread.php?t=283371
Hi, hope someone can help – I bought a book on amazon, but although after battling for a while I’ve managed to download the correct “older” version, while I can import it in Calibre, I cannot de-DRM it, and when trying to convert to EPUB I get a “DRM protected” error. I am running Calibre 4.7.0 with the latest tools on a Mac laptop running Mac OS 10.15.2 Catalina. I do hope someone can help, thank you!@

Did you have things working before updating to Catalina? Because I see it is finding a key which would have been a leftover from 32-bit Kindle for Mac 1.23 or earlier. Take a look at this post over at MobileRead and see if it helps:
https://www.mobileread.com/forums/showthread.php?p=3819708#post3819708
thank you Laura, yes I did see that, but it does not seem to work for me. All was fine before. For the moment I borrowed an old PC and managed to run an old version of kindle, which downloads AZW3 files, and converted those (I tried to go back to Calibre 4.6, but did not solve the original problem).
Going forward I do hope there is a fix for those people like me who are “stranded” on Catalina.
What version Kindle for Mac are you running? Was it downloaded from Amazon’s website or App Store? You had a working setup of Kindle for Mac (on the same computer) before you updated to Catalina? Which version Kindle for Mac was that and was it from Amazon’s website or App Store?

I have done this a few years ago and it now won’t work.
I’m trying to load plug in from file but it comes up with this message “InvalidPlugin: The plugin in u’C:\Users\DAMIAN\Downloads\DeDRM_tools-6.6.3.zip’ is invalid. It does not contain a top-level init.py file”
It might have been easier for me to get a kindle rather than a kobo reader.
Thanks
You’re trying to load the whole archive. Unzip that file and look in the DeDRM calibre plugin folder for the zip to load into calibre.
Thanks for that Laura, but when I’ve looked at the unzipped files there is only one other file zipped and thats “alfcrypto_src.zip”
Have I downloaded the right file? it’s 6.6.3
Thanks
See my previous reply: https://apprenticealf.wordpress.com/2012/09/10/drm-removal-tools-for-ebooks/comment-page-50/#comment-69917
Download DeDRM_tools_6.6.3.zip (first item under Assets) from here:
https://github.com/apprenticeharper/DeDRM_tools/releases/tag/v6.6.3
When you unzip that file, you will see 5 folders and a readme file. Inside the DeDRM_calibre_plugin folder, you will find a zip and a readme file. DeDRM_plugin.zip is what you load into calibre.
Right guys.
Sorry about this.
I’ve done that and added the zip file and it has come up in the file type plug in.
When I add a azw3 file (book) and try and convert to epub it still says this book is locked by DRM.
I guess I’m missing something?
Thanks
Post a log and we’ll take a look:

calibre.ebooks.DRMError: Cilka’s Journey
If that’s from or for an E-ink Kindle (not a Fire), then you need to enter the Kindle’s serial number into the DeDRM Plugin’s customization. (You can remove the Inept Epub DeDRM plugin. DeDRM replaces it.)
Thank you Laura, that has worked for most of them. I’m guessing that I downloaded the ones that didn’t work from an old kindle.
If I was to do it the other way, Kobo to Kindle, would I have to add my Kobo serial number to that plug in?
Thanks again
There’s a couple ways to remove DRM from Kobo ebooks. For books downloaded with the Kobo Desktop app or directly from a Kobo device, you use the Obok plugin. It works differently then the DeDRM plugin. You use the plugin itself to import the books into calibre. And yes, if you’re getting the books from an attached Kobo, I believe you need to have its serial number entered into the Obok plugin.
You can also download Kobo books from the website. Those will have Adobe DRM (if they have DRM.) You’ll open the .acsm file with Adobe Digital Editions 2.0.1 authorized with your Adobe ID on the same machine and user as calibre with DeDRM. Then add those to calibre in the usual way.
Hi. I’m using mac os 10.15.2 and I tried to install the DeDRM..but it is not working. Pop-up alarm said The application “DeDRM” can’t be opened.
What should I do?
First see this section of the FAQs:
https://github.com/apprenticeharper/DeDRM_tools/blob/master/FAQs.md#the-macintosh-application
But you may have further troubles trying to get things working on Catalina.
Haha i gave up to install this in my mac, and i just borrowed my mom’s window computer! It works!!! Thank you so much! You made my day :))
Catalina’s default unzip tool (Archive Utility) has trouble unzipping the DeDRM standalone app.
The easiest workaround is to download The Unarchiver from the App Store and use that to unzip the DeDRM standalone app.
The other workaround is to use Show Package Contents to reveal Contents > MacOS > droplet, then open a Terminal window and run: chmod +x [filepath to droplet]
Once you do one of the above, you should be able to open the DeDRM app using right-click-Open or System Prefs > Security to override Gatekeeper.
Hi,
It looks like something changed over the new year- Suddenly, books downloaded from Kindle for PC now get brought into calibre as KFX-ZIP instead of the KFX format, with no change on any of the apps themselves.
Did you update calibre? If so, try going back to 4.5. Or disable K4PC downloading KFX format.
Ah, yeah, I did. Didn’t think about it, but reverting back to 4.5 did the trick. Guess I’ll just stay there for now- the quality for KFX is just too good. Didn’t really have any reason to update anyway.
Hi
For about 4 years I have happily been using Dedrm app on books loaded into Adobe Editions from Internet Archive.
I recently replaced my hard drive and lost many preferences — although I still have Adobe editions (4.0.) as well as the Dedrm app.
Now, unfortunately, I cannot process a book.when I drop the pdf into the app I am re directed to configurations, and told to select my reader. When I select AE and try to Dedrm the book I am told the book needs to have a different extension. I tried reloading Dedrm but it made no difference.
I just noticed on my last attempt to Dedrm I was prompted an alert that say’s “Python quit unexpectedly” (I don’t know what Python is)
Any ideas?
Thanks, Scott
(Using Mac High Sierra)
Those are borrowed ebooks, correct? These tools are intended for books you own. We don’t provide help here for removing DRM from borrowed, rented, or subscription books.
Hi Friends – i have tried reinstalling the 1.24 version of kindle for PC, the deDRM and KFX plugins and deleting the books in the old directory from amazon and i still cannot get this to work. When i am adding book, i am using the single file AZW from “my contect folder.” I just want to move the books i purchased into my own library instead of living on amazon. Am i missing something really obvious?

TIA
There is currently a problem with KFX files, DeDRM, and calibre 4.6 and later. Workarounds include going back to calibre 4.5 or disabling downloads of KFX files from Kindle for PC.
Thanks – so in addition to earlier kindle PC version i should try earlier calibre? can i just uninstall or do i need to find all folders etc?
I believe you’ll be fine just installing calibre 4.5 without needing to uninstall your current version.
i am still unable to open the books. the title, data etc are being decrypted but i cannot open in calibre or convert. i am just supposed to import the book, correct? there is not another step i am missing? thank you again!

Hmmm, I’m not seeing what the problem is here. This is a book you’ve purchased, not Kindle Unlimited?
correct. if it makes any difference, i was able to get a couple books to work and i noticed that their file only contains one AZW file instead of AZW and AZW.MD
Ah. The ones with the .md file are KFX format. Maybe you do need to uninstall and reinstall calibre 4.5 to get that working again. But I think I’d probably just disable the download of KFX format and use the older formats if possible. See method 2 here:

That worked! I did not have to reinstall calibre, i just followed the instructions for PC kindle in link. in case anyone else is reading this, you do need to reload the library both in the browser and then to PC. The “collections” function isnt working properly but its not a big loss for me. i do want to ask a stupid question out of curiosity…isnt the purpose of the KFX plugin to bypass that? or is that something that worked with earlier versions? anyway, thank you again! i appreciate it 🙂
A small change was made in calibre 4.6 and later which affects DeDRM’s ability to process KFX files. So DeDRM needs to be updated for that. If you’ve stopped Kindle for PC from downloading KFX format, DeDRM has no trouble with the older formats. In fact, if you don’t need to deal with the KFX format, you’re fine updating to the latest version of calibre.
Does this not work on Catalina? I’m on 10.15.1 and did everything as instructed but when I add a book to Calibre it does not remove the DRM.
It may or may not. It depends on what type of book you’re trying to free and other details of your setup. Post a log:

Hi – I am using the standalone macOS DeDRM app (6.6.3). I am running macOS 10.14.6. I have successfully DeDRM’ed several hundred Kindle books (my purchases go back to 2012). However, I have two recently purchased books that I cannot DeDRM. I downloaded them directly from Amazon using the “Transfer via USB” option. Log details are below.

Are you sure you chose the correct E-ink Kindle device when downloading? And do you have its serial number entered correctly?
Hi Laura thanks for the reply. I re-downloaded the books and tried again. DeDRM 6.6.3 failed, but weirdly DeDRM 6.5.5 worked just fine. Not sure why that happened. I confirmed that both DeDRM versions used the correct serial number.
DeDRM 6.5.5 was the last version before KFX support was added so I would guess it’s related to that. Since you are better off avoiding KFX format with the standalone anyway, I doubt your missing much with that version.
Hi there,
Was going to use your useful application, the older version (2016), but my Mac, Catalina version 10.15.2, says it needed to be updated. I therefore removed this older application and downloaded the newest release. I did all the readme said, I think, but the Application can now not be opened (it is in the applications folder, where I moved it). How can I make the application work?
Addendum: There is no open with… option provided, so I cannot use The Unarchiver workaround.
Did you try opening the Unarchiver program first and then using that program’s Open command on the download? Just an idea.
Tried that too!
I get a text box saying: the contents of DeDRM.app cannot be extracted with The Unarchiver.
You might have done this too: Check to see that the download ends in extensions the Unarchiver will recognize like .zip and .rar. Sometimes you can get a download that has two extensions or other confusion. If that is the case use command-i on the file to bring up the information dialog box where you can type in a new name. Even if the extension is right I would recommend erasing and retyping the name just in case some weird invisible character corrupted the name. A bad extension would also result in what you reported that there is no Open With… menu choice. I guess you have also tried a redownload?
Tried that… no joy. Also, yes. I’ve re-downloaded and then trashed several times.
What about using the calibre plugin?
I got it to work!! Kind of by accident…
I used The Unarchiver on droplet in the MacOS Folder in the package contents of the DeDRM.app after moving the DeDRM.app to the applications folder. I got a notification from the Mac saying that it can’t be opened because it is from an unidentified developer. I solved this by allowing it in ‘Security and Privacy’. Then droplet extracted.
THEN, I used Terminal and typed in: chmod +x /Applications/DeDRM.app/Contents/MacOS/droplet. That worked.
THEN, I used The Unarchiver to extract the DeDRM.app. I got the ‘unidentified developer’ notification, went into ‘Security and Privacy’ and allowed it. And now I can open the app and use it!!
Whew! Yay!
Addendum 2: Terminal command does not work either.
chmod+x/Applications/DeDRM.app/Contents/MacOS/droplet
-bash: chmod+x/Applications/DeDRM.app/Contents/MacOS/droplet: No such file or directory
With the plugin loaded I’m still unable to remove the DRM. Here’s the cmd readout:

Did the trick! Thank you!
Unable to decode .epub file
Using DeDRM 6.6.3 on Mac OS Catalina and was unable to decode a .epub file.
I noticed in the DeDRM.app package (at Contents/Resources/) the DeDRM.app is not 64-bit compatible, but I don’t know if that explains the problem.
Here’s the DeDRM.log output…
People have been able to successfully use the Mac app on Catalina. Do you have Adobe Digital Editions authorized with your Adobe ID on the same machine and user as DeDRM? I know you can’t use ADE 2.0.1 on Catalina so it’s possible you have a version of Adobe DRM that cannot be removed.
Thanks Laura, I do have ADE (v4.5.4) and it did authorize the epub file that subsequently fails in DeDRM. In the past (prior to Mac OS Catalina), using the same version of ADE and (I think) an earlier version of DeDRM there was no problem. So you’re thinking that’s the issue?
I don’t know what the problem is then. The log doesn’t show anything — it seems cut off. It’s possible to get DRM that cannot be removed using ADE 3 and later. Is the book from the same ebookstore as ones you were able to decrypt before?
The book is indeed from the same ebookstore. I’m using ADE to down the retrieval from a .acsm file. Is there perhaps a preferable app to process the .acsm that would produce an .epub that works with DeDRM?
I doubt the problem is the hardened DRM then. If you could open it with Adobe Digital Editions 2.0.1 authorized with the same Adobe ID, then you would know it has DRM that can be removed. But ADE 2.0.1 is a 32-bit program.
Well the solution seems to be to use a pre-Catalina Apple machine. Running the same software versions (.acsm through ADE 4.5.4 to download the .epub and DeDRM 6.6.3 from there) on Mac OS Mojave did the trick.
Or run Mojave/High Sierra in a virtual machine on the Catalina Macintosh.
Others have reported being able to use the Mac app and the calibre plugin on Catalina, but I don’t know the details.
I have successfully used both DeDRM app and Calibre plugin on Catalina with ADE 4.5.10. As Laura notes, your log appears to be cut off. Is there more to it?
Also, the DeDRM.app you are running must be 64-bit or you wouldn’t be able to launch it in Catalina. However, it does contain a piece of 32-bit code called DeDRM Progress that is used if you drop more than one book on the standalone app. If you are trying to decrypt multiple books in one go, this could be the problem. Try one book at a time or see this post for a fix: https://github.com/apprenticeharper/DeDRM_tools/issues/925
Thanks Zola, your success on Catalina suggests that maybe my problems running DeDRM on Catalina involved a corrupt .epub original.
I re-downloaded the .epub before testing on Mojave, so I can’t yet rule out the Catalina attempt failed not because of anything between DeDRM and Catalina. Will test again later with Catalina and report back.
Thanks for clarifying what ‘DeDRM Progress.app’ does. I did see that that was 32-bit only and had wondered if that was the source of the error. But I was only dropping the one book, so per your note, it wasn’t in play and wasn’t the cause of the error.
Regarding “your log appears to be cut off. Is there more to it?”: That was the indeed the full extent of the log. I agree it seemed less than complete, but that’s all there was.
I couldn’t decode a Kindle ebook. Please help!
