Version 7.2.1 released on 11 April, 2021
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 in the Discussions area of Apprentice Harper’s GitHub repository. If you would like to report a bug, please 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.
Apprentice Alf’s Blog 
Does it work with current/latest Adobe Digital Editions DRM (4.x)?
It depends on whether the vendor is using the new DRM exclusively. Stick with ADE 2.0.1. Then if you can download the book with that, you know that the DRM is the older one that can be removed.
ADE is primarily for epub file formats, right?
To clarify, I’m talking in regards to borrowing library books.
Library books? Then you’re at the wrong blog.
Mainly epub. Can also open PDFs.
That’s what I thought. I’ve switched to Kindle, so borrowing library books is SOOOO much easier now. It always felt clunky when I had to transfer to my Nook.
One reason I’m glad I switched to a Kobo Aura One. Borrow books right on the device. Or just sync after checking out on the library website.
I am using Windows 7 and the latest Calibre version and tools and after trying everything in the readme and looking at the faq I can’t remove DRM. I bought the book through Amazon, it’s not a library book or Kindle Unlimited. Do I need Kindle for PC? Here is the log:

I figured out what the problem was. When I downloaded books, I had put my fire as the destination instead of my voyage. Apparently that made the difference because when I deleted them, went back and put the voyage as the destination, I could download them to my computer, then put them into Calibre and everything worked fine. So please disregard comment and log above:)
Yes, when downloading from the website, you need to select an E-ink Kindle (not a Fire) and have its serial number in the plugin customization.
I tried to do so with the DeDRM Mac Application and with the calibre plugin. But it always fails. When I download the file from the website it doesn’t have any file extension. Do I have to add it? Should it be .azw?
People have reported getting a file without an extension when using the Safari browser on Macs. Try using Chrome or Firefox instead.
Does this work in removing the DRM from ACSM files in order to convert them to PDFs?
Install Adobe Digital Editions 2.0.1, authorize it with an Adobe ID, and then open the ACSM file. Once the EPUB or PDF is downloaded, you can use this to remove the DRM.
Trying to convert an ePub I just downloaded from the Nook Windows 10 app.

That log shows that the tools aren’t installed.
Whoops – missed a line. Yes, the tools are installed, but you have’t tried importing a book.
I have used the DeDRM plug-in in the past successfully on my Mac. I can’t seem to get it to work for all book on the pc. This is on Windows 10 with Calibre 3.18 and DeDRM plugin 6.5.5. When importing azw3 files, I still get the “Cannot Convert due to DRM” popup for many books. Please advise.
If they’re downloaded from the website, then you need to make sure you’ve choosen an E-ink Kindle (not a Fire) for the device and entered its serial number correctly into the plugin customization.
just testing – I don’t seem to be able to post a comment…
OK, now it works. Linux user here (KDE based on Ubuntu 16.04)
no, I’m afraid, it doesn’t work: i can only post short messages but can’t post a calibre conversion error log…any idea?
The logs contain links to the FAQs, and they can get stuck in spam/moderation if there are more than a couple. Try posting again with those removed.

That’s a conversion log. Post an import log.
As Paul said, we need the debug log from when you add the book to calibre. Here’s how to get it:

not sure I removed the right lines – couldn’t see any link to the FAQ, really
these are the lines I removed:

Don’t drag books downloaded using the Kobo desktop app onto calibre. Use the obok plugin. It will show you a list of books that can be imported.
How do I use the obok plugin? I don’t see anything related to obok on Calibre except that when I look at preferences/plugins, I see that it is installed.
It should be on the main toolbar. Restart calibre after installing. If it’s still not there, go to Preferences > “Toolbars & menus” to add it.
Preferences > “Toolbars & menus” did the job, thanks.
sorry about the previously messy post. From the beginning: Linux KDE (based on Ubuntu 16.04), Calibre 3.18, Wine 1.6.2 (install via Synaptics), Kindle for PC installed via Winetricks. Kindle does not log in (except after getting some temp password from Amazon) and does not sync. I have a back-up of my Kindle Content + am following the read-me file at DeDRM 6.5.5/calibre_plugin.
here is my log – hope someone can help. Thanks!

If you only have Kindle for PC, you must get a working version installed. The encryption key is per-install, not per-account.
If you mean you had an E-Ink Kindle that’s no longer working, you should enter that old KIndle’s serial number in the plugin’s preferences
And if you have an e-ink Kindle registered to your account, you have to re-download your ebooks from the “Manage Your Content and Devices” – “Your Content” page in your account with “Download & transfer via USB” (the 3 “…” beside each ebook). Shortlink is “amazon.com/myk” in the URL-Field of your browser.
If yo do not have an e-ink Kindle and the Kindle for Windows is not working, it might be worth getting a used (non-registered!) e-ink Kindle from ebay or elsewhere. It could even be broken, as long as you read the serial number for linking it to your account and configuring DeDRM.
If you get a working install of KIndle for PC, I see another problem in this line:
wine: cannot find L”C:\windows\system32\python.exe”
For some reason some Linux systems have a problem with DeDRM finding Python. (You do need to have Python and PyCrypto installed under Wine.) Try manually running the key retrieval script under Wine, and import the key into calibre:
wine python.exe “/home/weword/.config/calibre/plugins/DeDRM/libraryfiles/kindlekey.py” “/home/weword/winekeysdir”
(You may need to create /home/weword/winekeysdir first, and then the retrieved key(s) will get put there.)
thanx for your feedback. I don’t have/never had an E-ink Kindle. I seem to understand that I should delete the version of Kindle for PC I installed via Winetricks and get Kindle for PC 1.17 from somewhere else. Any idea where?
Laura, I’m afraid, I don’t quite understand what you mean when you say
Try manually running the key retrieval script under Wine, and import the key into calibre:
wine python.exe “/home/weword/.config/calibre/plugins/DeDRM/libraryfiles/kindlekey.py” “/home/weword/winekeysdir”
(You may need to create /home/weword/winekeysdir first, and then the retrieved key(s) will get put there.)
Hmm, not sure how to explain. But first get Kindle for PC working. And do you have Python and PyCrypto installed under Wine?
I do have Python and PyCrypto installed under Wine. For some reason, I can’t get Kindle for Pc working though. I’ll try again and report back.
OK, I finally got Kindle work under Wine (I re-install everything from scratch on a freshly-installed Ubuntu 16.04) + downloaded ebooks.
so everything – according to the read-me at DeDRM 6.5.5 is now in place (including Python and PyCrypto).
I’m still totally stuck at the line (as on read-me and mentioned by Laura) “Run

DeDRM is trying to run the key retrieval Python script (kindlekey.py), but it can’t find python.exe in order to do it. So the workaround is to do it manually and then import the key into the DeDRM plugin yourself.
open a command line window (terminal/shell) in your host unix system and run the kindleky.py script manually under wine by typing the appropriate command into the command line.
many thanks Paul and Laura, I’ve finally figured it out 🙂 more later
Hi all,
Can someone remind me of the link for ADE 1.72, please? I’m going to give setting it up in Wine on PCLOS and cannot find the link on Adobe.com.
As well any setup pointers from Linux users here will be jolly welcome! Thanks.
ADE 1.7.2 is no longer available from Adobe. Besides, you do not want ADE 1.7,2 as there are places you cannot download ePub using it. That includes places like Google Play and Overdrive. You need at least ADE 2.0.1. You can install ADE 2.0.1 under Linux, but you have to jump through hoops to do so. The link below is to ADE 2.0.1
http://download.adobe.com/pub/adobe/digitaleditions/ADE_2.0_Installer.exe
I didn’t know that. Thanks very much for replying. I’ll use 2.0.1 then.
thanx for your feedback. I don’t have/never had an E-ink Kindle. I seem to understand that I should delete the version of Kindle for PC I installed via Winetricks and get Kindle for PC 1.17 from somewhere else. Any idea where?
See this post over at MobileRead:
https://www.mobileread.com/forums/showthread.php?t=283371
Well, Firefox completely butchered that. Here are the Pastebins instead.
https://pastebin.com/pcb89yuk
https://pastebin.com/C0KwwVdi
The second pastebin says the book was DRM-free to begin with.
As for the first, was that book downloaded to the current installation of Kindle for PC on the same machine and user as calibre/DeDRM?
I successfully installed the plugin and restarted calibre, but it is not removing DRM and can’t open the ebook. I got this kindle book from the library. Please help. Thank you
We don’t help with DRM removal from library books.
I bought a DRM protected book from Kobo. The OBOK plug-in to Calibre won’t download it. The file on my Mac may be: /Users/HBrazee/Library/Application Support/Kobo/Kobo Desktop Edition/kepub/c0da1485-0013-4e6b-8ce1-5802296ce85f which is 4.9MB or maybe 27ac5195-716c-48ec-a3d6-928ddcf35d7d, which has the same time/date stamp, and is 1.1MB. Is it possible to get this broken and in my Calibre library?
Download it as an ePub and strip the DRM from there.
When I try to download it from the Kobo site, I get the following file: URLLink.acsm.
That’s usual with a DRMed ePub. You’ll have to read it with your Digital Reader and “add” it to Calibre.
I tried to open my URRLink.acsm to Adobe Digital Editions 4.5 and got “Unable to download Error getting license. License Server Communication Problem: E_ADEPT_REQUEST_EXPIRED”. Checking my help, I see that my computer is already authorized. The Reader app tells me that this item has expired.
You have to dump ADE 4.5. There’s a good chance of getting an ePub you can not remove the DRM from. You want ADE 2.0.1. As for the error message, it’s a problem on the DRM server and will eventually be sorted.
Yes, use 2.0.1 if you want to be able to remove the DRM. 4.5 can use a new DRM scheme the tools don’t handle.
How long ago did you get the .acsm file? Perhaps you’ll need to get a fresh copy.
My .ascm file was too old. I didn’t know that they had expiration dates. Thanks.
Obok is still working for me.
For the file downloaded from the website, you’ll need Adobe Digital Editions 2.0.1 authorized with an Adobe ID. And the DeDRM plugin. Open the acsm file with ADE. Then add the epub to calibre.
I installed ADE and Kindle for PC via Winetricks. So I got ADE 1.72 and PC Kindle 1.17. (to get ADE 2.0, I’d have ‘use prefix made with WINEARCH=win32’ and I wouldn’t know where to start with that so I left it at 1.72.
I installed the plugin in Calibre. But then one of 2 books from amz did not get deDRMed so I thought I must follow the steps for linux users and do #s 6 and 7 but,
I’m zero at command lines etc. hence my glaringly ‘dumb’ question. I’m using linux pclos KDE5.
Since i don’t know and could find any info as to the exact command to use ( WineHQ didn’t say anything specific either) .I could not do these ‘install’
Install Python 2.7.x using
msiexec /i python-2.7.8.msi. Accept all defaults.Install PyCrypto 2.1. Accept all defaults.
So for #6, I right click the actual .exe file and chose ‘Open with Wine Windows Program Loader’ it got as far as choose directory to install then nothing. For # 7, I would do the same right click had #6 worked.
Any linux users can point me in the right direction please?
You have to dump ADE 1.7.2 as it doesn’t fully work. You want to get ADe 2.0.1 and install that. Otherwise, some places you download DRMed ePub, it won’t work such as Overdrive and Google Play.
Does having ADE 1.72 affects how Kindle PC 1.17 works? They are housed in the same wine prefix.
Here’s the log for the book. Should have posted it as well. Sorry.

No. These tools are for books you’ve purchased yourself and for your own personal use.
Ronny, you are aware that you just publicly admitted you and your friend committed fraud and piracy, or at least intended to do so?
So I installed the plug-in in calibre but I still cannot convert amazon ebooks. I read in the comments that you have to select a Kindle e ink and not a kindle fire when downloading the ebook from amazon in order to be able to convert it on calibre? I only have a kindle fire, is there a way around it?

Hi folks, hoping I can get some help on this.
I am trying to get the DRM removed from some Nook books I purchased years ago so that I can move them to my computer. The debug log is as below. I downloaded these books from my nook account on the windows 10 app on a friend’s computer and then put them on to a harddrive to get them to my computer because I do not have a PC.
It looks like there was a problem with applying my key? But I’m not entirely sure how to decode what the exception was. Thanks in advance!

I take it you were able to retrieve your key by entering your B&N account email and password into the plugin? Generally people seem to have better luck with the old Nook for PC program rather than the Windows app.

I am using DeDRM with Calibre and Kindle for PC under Windows 10. No problems with my setup. I would like to DeDRM Kindle books from another account (my wife’s). I set up Kindle for PC (1.17) on another PC registered to her account and could remove DRM that way. However I would like to know if it’s possible to have the Calibre plugin work with two Amazon accounts on the same computer.
My wife and I have two Amazon accounts too. But I went to Amazon and configured our accounts so that when we buy Kindle books, both accounts get the books. Because of this, I can load all of the books into Calibre with my DRM removal. I don’t need a separate account.
Yes, Amazon Family! Definitely recommend this. Makes sharing books with one other account pretty seamless. Has to be someone like a spouse because you also have access to each others’ stored payment methods.
You can export and import keys in DeDRM, but know that Kindle keys are device or app installation specific even for the same account.
Hello! Been a user of your plugin for a long time, and it has helped me a lot. Now, suddenly it didn’t work for a certain book. I first removed your plugin (6.5.4), then downloaded the newest version (6.5.5) and installed it. Still didn’t work, so I ran Calibre in debug mode and got the below log. Your help would be much appreciated! Thanks:)

Thanks, Laura! It worked 🙂
I am clueless on what to do with this update. I’ve read some ReadMe files, but am still clueless. Sorry that I’m so dumb, but is there a “for dummies” set of instructions?
I’ve installed it on c=my calibre but I haven’t tried it out yet. I don’t think it makes any difference unless you have KFX files, and then I think you need jhowell’s KFX import plugin installed as well. https://www.mobileread.com/forums/showthread.php?t=291290
Apprentice Harper has released version 6.6.0 of the tools:
https://apprenticealf.wordpress.com/2018/04/06/dedrm-tools-6-6-0-released/
This release gives initial KFX support to the plugin. No doubt some bugs need to be squashed, and the FAQs need to be updated. If you are not interested in removing DRM from the Kindle KFX format, then there is no need to update.
— Alf.
Alf, just to confirm: will adding the file DeDRM_plugin.zip to Calibre overwrite previous versions of the file or do we need to remove the old DeDRM plugin first?
Adding the new version (6.6.0) replaced the older version (6.5.5) for me.
I don’t remember how I added it the first time. I remember that it wasn’t obvious.
Here are the steps, Howard:

You got that after clicking on the “Load plugin from file” button and then selecting the “DeDRM_plugin.zip” file?
I was told it had been installed successfully but I’m also using Calibre 3.21
Yep. I just tried it again (with the updated Calibre), same error. Unzipping I don’t find a “top-level init.py”.
Unzip that file. Then load the zip that’s in the DeDRM_calibre_plugin folder.
OK. That was confusing me. Especially since there are directories for DeDrm_Calibre_plugin, DeDRM_Macintosh_Application, (and windows), Obok_calibre_plugin, & other tools such as Kobo. But I see that they all have older dates. So I installed everything. I expect I won’t know anything different, but am up-to-date for future needs.
Howard, you should only need the DeDRM_plugin.zip file installed in Calibre. Do not unzip it but install the file as is.
The DeDRM_Macintosh_Application (and its Windows counterpart) are standalone applications for the appropriate OS for use without Calibre.
As xromad said, you really only need the DeDRM calibre plugin. Obok is just for books downloaded with Kobo Desktop (or a Kobo ereader), but you can also download Kobo epubs with ADE 2.0.1 and use DeDRM on them instead. More than likely you can ignore everything else in there.
Thanks, Paul!
Alf – thank you so much for your de-DRM tool, and for working on a KFX fix too. You put a lot of work into providing this brilliant service – do you have a donations page?
Chris.
I appreciate the offer, but we do not accept donations for these tools.
— Alf.
Been months at trying to decrypt Neowing DRM. Appear to be epub+zip. JPGs are encrypted in some way. Able to help out Alf?
I see someone (maybe you?) has opened an issue for this at Apprentice Harper’s GitHub. I’d keep an eye out there for any news.

Looks like DRM removal was successful. The problem seems to be the conversion by the KFX Input plugin. I’d go to the link given in the log:
“KFX Input plugin help is available at https://www.mobileread.com/forums/showthread.php?t=291290“
That error is caused by a bug in the KFX Input plugin. I will release a fix for it early next week.
I was trying to import a Kindle for Android e-book with a .kfx file format, but it didn’t work, as the format Calibre showed was KFX-ZIP. Am I doing something wrong, or is there just no way to remove the DRM from Kindle for Android books and convert them to another format? Below is the log:

No, just Kindle for PC/Mac or E-ink Kindles (not Fires).
I’ve seen others on other forums say that they’ve been able to successfully import Kindle for Android e-books into Calibre using the DeDRM tools and the KFX Input Plugin.
From the KFX Input MobileRead page:
“No workable import method currently exists for Fire tablets or the Kindle for iOS/Android apps.”
There was once a way to decrypt books from Kindle for Android, but changes to the app broke that method quite a while ago.
You said that changes to the app broke that method quite a while ago. In that case, since you can sideload apps on Android, would it be possible to get an older version of the app and use that one instead? If not, is there never going to be a way to decrypt e-books from Kindle for Android books?
And from that thread, here is what one person said with regards to importing e-books from Kindle for Android:
“First I had to locate the kfx file on my phone, which took a while. (The files were in /storage/emulated/0/Android/data/com.amazon.kindle/files but I don’t know if that’s universal I found it doing a search for .kfx.)
Then I zipped the whole directory labelled with the B0* book ID.
I emailed it to myself (because it beat messing around trying to set up mtpfs crap or get adb to work so I could transfer files). I also sent along with the .ticr file and the one that was just a string of numbers and characters from the files directory. (I don’t know if those two files are necessary, but I was recreating the directory structure.)
On my desktop, where I have Calibre, I created a “KFX” directory. I dropped the .ticr file and the other in the folder root and then extracted the zipped B0* folder.
I followed your setup directions on the desktop, used the extracted B0* directory as the import source, and bam, it worked like a charm.”
I don’t know. I’ve never messed with it myself. It involved making a backup file to extract the key from, and the app stopped allowing the creation of a backup file. Look in the help for the Kindle for Android section of the plugin customization for more info. Before that, people made patches to Kindle for Android which you can still find in the Other Tools folder. But I imagine those are too old to work anymore.
All books in KFX format are encrypted, but if the publisher has chosen to not use DRM on a particular book it will have a generic key that these tools can handle. For books that do use DRM the particular key associated with the app installation is needed in order to remove it.
There was discussion back in December 2015 in these comments about side loading an older apk (version 4.17 or earlier) to get around the backup restriction. I don’t know if that method is still workable.
Or if you have root access on your device you may be able find the file with the key in the app’s private storage.
I do have root access on my Android phone. Is there a particular place I should look for this file with the key?
With root maybe you can still create the backup.ab file? That’s what the Kindle for Android section of the DeDRM plugin customization asks for to get the key.
How did the person at that other forum get their Android key? Or was that a book that would have a generic key (as jhowell mentions)?
How would I go about trying to create the backup.ab file? As for that person, I would assume that his or her book had a generic key, as there was no mention of this file needing to be created when he or she explained how he or she did it.
I did a bit of research and figured out how to do it. I sideloaded an older version of the Amazon Kindle Android app, v4.15.0.48 and created the backup.ab file using the “adb backup com.amazon.kindle” command. The size of the backup.ab file created, which seems to be important, was 112 MB. I imported this file into Calibre, and since I was using an older version of the app, it used the .prc file format for the e-book I was trying to remove the DRM from. Upon importing it to Calibre, it was recognized as an .azw3 file, the DRM was removed, and I was able to open it.
Thanks for the suggestions! Although I’m curious if it means there is no way to remove the DRM from e-books from the newer versions of the Amazon Kindle app.
I don’t think that much attention is being paid to the Kindle for Android app as a platform for DRM removal because using Kindle for PC/Mac instead is so simple and reliable.
Ah, they must have stopped allowing backups before Kindle for Android supported KFX. If you allowed it to update, it might keep the same key. But more likely, it would consider it a new installation and change the key.
As jhowell says, there’s not much interest in supporting Kindle for Android since Kindle for PC/Mac is easier. There used to be some books which would not download to Kindle for PC/Mac, but could be downloaded to Kindle for Android or an E-ink Kindle. So for people without E-ink Kindles, a workaround for Kindle for Android was useful. Now I believe Kindle for PC/Mac can handle everything that Kindle for Android can so there’s not much reason to mess with it.
