DRM Removal Tools for eBooks

Posted on by

Version 6.8.0 released on 18 June, 2020

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.

    • You’ve unzipped one step too far. There’s the Tools zip file. Unzip that and you’ll find the DeDRM_plugin zip file. The alfcrypto_src.zip file is inside that.

    • Or you may have downloaded the wrong file. You want the first link under Assets on the release page. It should be DeDRM_tools_6.8.0.zip with an underscore after “tools”, not a hyphen. Then as Paul said, unzip that to find DeDRM_Plugin.zip. Leave that zipped.

  4. Hello: I downloaded v6.8.0 today and cannot find the Alf DEDRM standalone app. Is it no longer available. I do not like calibre so have been using the standalone app for years on OSX.

    Reply

    • The stand-alone tools were dropped in 6.7, IIRC.

      You could probably just open your existing application (Show Package Contents) and replace the .py files in there with the .py files from the plugin’s unzipped contents.

      Or just get calibre. How on earth do you keep track of your ebooks without calibre?

      Reply

      • Thankyou Paul. I am old fashion (I know), so “which books I have” is easy for me, as they reside on my lovely physical bookshelves. I use the dedrm ebooks to either read while travelling or more often, markup the PDF version or listen to them as I cook or walk etc.. but for reading I still really really prefer the physical books. I have physical and digital of all the books.

        I am using Catalina 10.15.5 and have the DEDRM standalone tool v 6.6.3 successfully dedrm for pubs and PDFs. But no Kindle files are working (azw file previously dl and dedrm (like a year ago on my old high Sierra MacBook) are not working).

        I have not swapped out any .py files yet.

        dedrm.log is showing a python module fail. “ImportError: No module named Crypto.Cipher”
        So wanted to check before swapping out .py files as you suggest. I have the DEDRM standalone version from my old MacBook 6.4.3 that did work. 6.4.3 does not work on Catalina as it is 32bit.

        Are the .py files I swap out, these 3?

        • I recommend that you just download and install calibre and the plugin. Use calibre to remove the DRM (by importing the book), and then you can just use the file from the calibre library as you like. You don’t have to use calibre any more than that, and it’ll be a lot easier than trying to get a working version of the DeDRM AppleScript application working on Catalina. (Which might be possible, but I’m not certain that it is.)

          • many thanks Paul, Zola and ingo. I will try as Zola done. I really like the simplicity of the standalone DEDRM app. Doesn’t create any libraries etc… self-manages. Very clean for me.

            if that fails, I was thinking could use parallel app to run an early version of kindle for PC. I will likely buy ePUB and not my preferred kindles before willing to install Calibre on my Mac. I am going to try and boot off my old Mac HD as an external if I can find a cable as adapters are preventing it.

            • This was my process, yours may vary.

              Open Terminal window:

              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 appears offering to install command line developer tools, choose Install
              try again: sudo python -m pip install pycrypto
              if after installing pycrypto decryption fails with error pylzma error
              type: sudo python -m pip install pylzma

              Good luck!

    • It is my guess, that the standalone for a few reasons was not working anymore. Depending on which version of Mac OS you are working, it might gradually fail.
      For instance: I am still on mojave (might skip Catalina), and I use standalone DeDRM 6.6.3 which might still be on Github. It works for Kindle eInk (serial number as key, no KFX-ebooks) and the old Adobe DRM on EPub (2.0?).
      It does not work any longer ebooks from Kindle for Mac, even the modified non-KFX-version I use.
      These have to be imported with Calibre to be stripped of DRM, I know no other solution.

      • FWIW, I have successfully modified 6.6.3 by replacing kindlekey.py inside 6.6.3 with kindlekey.py from 6.8.0. Standalone app now works with K4Mac 1.28.0 on Catalina and High Sierra.

      • Seem to remember this question popped up here before, and it does not look like it is Adobe. Also the webpage with ebooks offers a reading app for iOS and Google (Android store).
        The ebooks covers look like manga.
        @ Ruppi If there is a free or cheap one, you could get it and test it, but my guess is, you will not be able to remove DRM.
        EPUB for Manga is sometimes pictures with a html TOC and some html so you can page through.
        The pictures are probably encoded, and also they most probably use some homebrewed DRM, as said not Adobe (and I am not even sure, DeDRM would decode the pictures if it where Adobe DRM).

    • @Ruppi
      Are you certain the ebook you puchased from booklive.jp is in fact an EPUB? Booklive also sells ebooks in proprietary XMDF and “.book” formats which are used only in Japan and are completely unrelated to EPUB (more than just DRM-wise). I’m guessing they (or rather most of their publishers) have switched to EPUB by now for their newer titles, but many older ebooks may still be available olny in these other formats that were common before EPUB got widely adopted among Japanese publishers.

      I’m just saying this because people often tend to use EPUB and ebook as synonyms and I don’t know if you’re a technical enough person to be sure you actually got an EPUB format book from them.

    • Is Adobe Digital Editions authorized with your Adobe ID and on the same machine and user as calibre with DeDRM?

      If this ebookstore is using the hardened Adobe DRM, DeDRM won’t work. If you have access to a machine which can run 32-bit programs (Windows or earlier Mac OS), you could see if you can download the book with ADE version 2.0.1 authorized with the same Adobe ID.

  8. Hi, it looks like DeDrm can’t find the encryption key. I have a Kindle 4 registered with Amazon and couldn’t download the book to my Kindle as it’s not compatible. So I tried downloading it to Kindle for PC and from there into Calibre. When trying to configure DeDRM by selecting Kindle for PC, I get a message that it can’t find the default key.

    which tool was used: Calibre 4.20 for pc
    which OS you are using: Windows 10
    where the ebook file came from (device or application): Kindle for PC 1.26. Book is in KFX format
    any error messages: None, but can’t open it with Calibre

      • Hi Laura,

        I made the upgrade and it picked up the default key. It does, however, look like there is something wrong with the KFX Input plugin’s processing as I can’t open, or convert, the book with Calibre. It does open in Kindle for PC.

  9. Hi, I’m not sure what I’m doing wrong. I have kindle for PC v. 1.24.3. i’m pretty sure I’ve installed the plugins correctly into Calibre. The debug log says that it was successful, but it also says that the book was successfully added to Calibre; however, it won’t open and says that it’s in “htmlz” format. Here’s the debug log. All help appreciated, thank you!

  10. Has something changed with Amazon and activating old versions of the Kindle software. I have a Mojave VM with Kindle 1.17 installed and last used it a couple of weeks ago. I tried today and the app had spontaneously deauthorised itself, and will no longer accept my (valid) credentials. It just says, “enter a valid email or phone number”. I can still log into my Amazon account so I know the credentials are valid. Are they blocking older clients now?

    • I didn’t have a problem on Monday, 6 Jul 20 but let me test it.

      OK, I just purchased a Kindle book on Amazon.com and downloaded it to Kindle for Mac 1.17 on my iMac running MacOS 10.13.6 (High Sierra) without a problem. I then imported it into Calibre 3.48.

        • Hmm, good to know it might just be me. It has been working fine for a while, so maybe I will reinstall the app. Thanks for the information

          Reply

          • OK. I think I know what happened. I moved the VM to my new Mac and something in the environment changed so that Kindle got confused. Removing it and purging anything kindle related from /Library and ~/Library eventually let me install it again and reregister. Ironically the book I purchased had no DRM anyway, so I am not certain everything is working with DeDRM/Calibre but at least I have the Kindle behaving.

    • Did you find a solution for this? I’m on a PC and have literally tried everything. I accidentally updated to 1.26 then I de-installed it and re-installed 1.17, but then it kept telling me to enter a valid email or phone number. Installing, de-installing, re-installing… deregistering the app over on Amazon, but it still keeps telling me that I need to enter a valid email or phone number, but I’m 100% sure that the credentials are valid. I’ve removed the My Kindle content and the file in the C:Users\app\local but nothing. It keeps telling me that I need to enter a valid email or phone number. I’m literally crying tears of frustration because I just don’t get why it doesn’t work anymore, so any wisdom anyone can offer is appreciated. Thanks in advance!

  11. hi, I have no idea what does zip fil, unzipped etc. means, I tried my hardest and reached till here…can anyone please explain me what do I need to do to convert my ebooks to pdf.

    • I’m not sure where to begin if you aren’t aware of what unzipping a zip file means. I think you’ll need to have someone walk you through the instructions in person.

    • Yes, it worked:

      DeDRM v6.8.0: Decrypted with new default key after 0.5 seconds

      With calibre open, attach your Kobo to your computer with a USB cord. On your Kobo, tap ok to connect to computer. In calibre, select the book(s) you want and click the Send to Device button. When you’re done, eject the device before disconnecting the USB cable.

  14. I have a recent (2019) Kindle Paperwhite. I downloaded the deDRM folder and unzipped it to a separate file. I then opened my Calibre file and clicked down to the plugins page. There was no option to install from “Load plugin from file”, so I have no way to install the deDRM plugin. I imagine others have had a similar problem and would be interested in how to work around this issue.
    Thanks for any help.

      I just launched Calibre and went to Calibre>Preferences>Plugins. At the bottom of the Plugins window are 6 buttons in two rows and the right hand button of the bottom row is labeled “Load plugin from file” with the “L” underlined. This is in MacOS, but I’d expect it to be the same in Windows.

  16. First, THANK you so much for this tool! I have successfully used the plugin with Calibre to remove DRM from an EPUB originally purchased from Sony for use with the Pocket eReader (one of many). But this is only one step toward my goal, which is still unsuccessful:

    I am very much hoping to upload ALL of my formerly-Sony eBooks to my Google Play library, so that I can get to them “in the cloud” with my Android device. I just attempted to do so with the above DeDRM’d EPUB (from the Calibre directory), but sadly Google is still giving me a “Processing Failed” message.

    Do you know of anyone else who has successfully done this? Do you know of anything more I can do to get Google Play to cooperate? Solving this would be SO awesome…

  17. I recently purchased “Ghost in the Wires” for my Kindle PaperWhite. I made the purchase from my Amazon account on the web, using Chrome. Am running Windows 7, on a Dell Laptop (Latitude E6530). I enjoyed reading the book, but when I imported it into Calibre with DE_DRM properly installed and updated, it couldn’t remove the copy protection. What follows is the contents of the log. Thanks very much for what you do! All the best, Alan

  18. Hello: I hope someone can help sort this unusual situation. I migrated to a new computer and my dedrm solution stopped working. I can dedrm epubs and previously downloaded kindle from my account. However if I download the same book I purchased 2 years back and try to dedrm, I encounter problems. As a test, I found this old file from 2 years back, in one of my back up drives, and tested dedrm, and it worked perfectly (dedrm standalone tool 6.4.3, kindle for mac 1.12). But that very same file dl this week, failed dedrm, still using the same environment (dedrm standalone tool 6.4.3, kindle for mac 1.12).

    The DEDRM log is showing a key was generated but still a problem. Log below. Dedrm log from using standalone tool 6.6.3.

    I looked in the com.apprenticealf.dedrm directory and there was no sub folder “newKeys”. I created one and retested. Same result. In fact alfs tool deleted my newly created. directory. Why are the keys not being saved in .k4i?

    Workaround
    1. looked further in the com.apprenticealf.dedrm directory and saw a bunch of files not ending in .k4i (kindle key) but DER (which is normally an adobe key I had understoodb, but it was named kindlekey24.der.
    2. changed the extension from .der to .k4i e.g. kindlekey24.k4i
    3. manually loaded the “new key”, called kindlekey24.k4i into the old OSX DEDRM standalone app (6.4.3). DEDRM worked. Which is fabulous as finally my book is dedrmd.

    Now how to get it back to automatically do this.?

    Environment is High Sierra using a very old Kindle for Mac (1.12?).
    The dedrm log is generated from using DEDRM standalone tool 6.6.3
    The kindle was dedrm using the DEDRM standalone tool 6.4.3

    There was an error with 1 ebook:
    TESTTEST.EBOK.azw couldn’t be decrypted.

    NOTE: although log file says it saved key as kindlekey1.k4i. It in fact did not. but kindlekey1.DER

    • The standalone DeDRM apps are no longer being updated so it may be tough to get things working on a new computer with new downloads. I’m surprised K4Mac 1.12 is still working. I don’t know what is happening with the key saving – except keys don’t automatically get saved unless they unlock a book.

      Reply

  19. Update: Amazon has made changes to the KFX encryption since this release which affect Kindle for PC/Mac versions 1.27 and later. This release should work on all books downloaded with Kindle for PC/Mac version 1.26 or earlier. Books which require the later versions of Kindle for PC/Mac will not be able to be decrypted at this time.

    How can we tell which version of the kindle for pc the books require? Every book i have tried says it is DRM locked even though I have the DeDRM tools installed and I have tried previous versions of Kindle and it is still locked.

    • For some reason it’s not finding Python under wine. You could try running kindlekey.py manually. Or temporary install Windows calibre with DeDRM. Then after you’ve decrypted a book, save the key and import it into the DeDRM plugin in Linux calibre.

      • I installed caliber along with DeDRM under Wine, but I keep getting error messages when I try to add books:

        I managed install 1 book and I assumed the DeDRM worked (I discovered later that it didn’t, and I haven’t been able to add any other books) when I saw a key. I saved and imported it to my Linux calibre, and got this when I added a few books:

        Could you point me to where I can learn how to run kindeykey.py manually? A search for the windows calibre issue yielded several mentions of anti-virus software being the issue, which doesn’t apply to my system, so that’s a dead end.

        Thank you for your help.

        • I mean from the command line. You can see what DeDRM tries to do in the log:

          Command line: ‘wine python.exe “/home/sherwood/.config/calibre/plugins/DeDRM/libraryfiles/kindlekey.py” “/home/sherwood/.config/calibre/plugins/DeDRM/libraryfiles/winekeysdir”‘

          So something like that. Then import the key into DeDRM.

  22. DeDRM 6.8.0 & Calibre 4.21
    Windows 10
    eBooks purchased from Amazon & downloaded from Amazon (not the kindle app!)

    My issue is that the plugin isn’t removing the DRM on ANY ebook at all! 😦
    I do appreciate your help!

  23. Someone, anyone, remind me please -should the older version of the obok plugin be removed before installing the new one in Calibre?
    Thanks.

    • All the Kindle books I see are either successfully decrypted or unencrypted. There are also some epubs which either don’t have DRM or don’t appear to have have a type of DRM that these tools recognize. I may well have missed something in all that. Please provide a log of adding just ONE book that you’re having trouble with.

      Reply

      • Hello, thank you for your answer.

        In the end none of the books that appear in that log could be opened in Calibre. When i Tried to open the “converted” files through Calibre, Kindle showed up instead. In the end I had to convert those files to PDF format since another converter couldn’t do it properly to epub. Herein you can find the log for one of the “problem books”. It was supposedly converted, however it never opened in Caliber like the rest. All the problem books are in azw4 format. Regards

    • If that was downloaded from the website for an E-ink Kindle (not a Fire), then add the Kindle’s serial number to DeDRM’s customization.

  26. Hi there,
    My question may be felt as repeated or not useful, but still I am requesting members to help me in this. There are books available only for specific devices and cannot be downloaded to Windows, PC etc. I am getting “PCMAC_126_Delivery_Error_OpenGL”. Same book can be downloaded to the Kindle for Android. My question is it possible to remove DRM from those books, like copying them to PC on un rooted phone. If that is possible then how can it be achieved. Any steps will be helpful. Thanks in advance.
