Version 6.6.1 released on 2 June, 2018
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.

If that book is from an E-ink Kindle (not a Fire), then you need to put its serial number into the plugin customization.
Your plugin for Calibre works like a charm. Thank you for this fast, user-friendly & very functional solution!
I would greatly appreciate any help please. I downloaded a bunch of new books on Amazon directly to my Kindle and now want to get them into my Calibre library and switched from AZW3 to Epub format so everything is the same. I’ve updated calibre and downloaded the 6.61 tool pack. I’m doing something wrong, but I’m not sure what. Help please?
Thank you!

Your Kindle needs to be E-ink — not a Fire — and you need to put its serial number into the plugin customization.
I cannot open the new DeDRM app for Mac. (I am using 10.11.6) I have been using an older version of DeDRM with no problem for at least a year. New app says “cannot open”. I have my system preferences security settings set on “allow apps form anywhere”. I have repeatedly tried right clicking, control clicking and even re-downloading and unzipping using Ziprar, no difference.
Yeah, there are issues with the current stand-alone apps. This thread over at GitHub discusses some workarounds for the Mac app:
https://github.com/apprenticeharper/DeDRM_tools/issues/505
Or you could stick with 6.5.5.
Thanks Laura–where can i find 6.5.5?
Here’s the page with all past releases:

Appreciate any help
You’re trying to load the whole archive. Unzip DeDRM_tools_6.6.1.zip and look in the DeDRM_calibre_plugin folder for DeDRM_plugin.zip.
I am using Calibre 3.28 with DeDRM 6.6.1. on Windows 7/64 Bit. Installation runs like a charm but I am still not able to import ebooks directly from my Kindle Paperwhite to Calibire because Calibre tells me that ebooks in KFX format cannot be imported and I have to use the download option in Amazon.
But when I remember right DeDRM can handle KFX. Do you maybe know what I have done wrong?
Many thnaks in advance,
best regards
Thomas
You also need the KFX Input plugin.

I’ve been trying to convert after installing both plugins to no avail. The DRM blocks it every time still. No clue what I could be doing wrong.
First test a different file format from the Kindle, AZW, AZW3, Mobi. Start Calibre in Debug mode, and import that fileformat, look in the log wether the book had DRM and was successfully DeDRMed.
– if the log shows the book to have no DRM, try a different book, until you get one with DRM
– if even this book cannot be DeDRMed, configure the plugin with the serial number of the Kindle (must be an eInk, NOT Fire), entered without spaces
– try again with a newly copied book from the Kindle
– if the import works and DeDRM also, but only on AZW, AZW, Mobi etc., not KFX, you may be currently out of luck, some books still do not work (I think currently my success rate is 9 from 10 KFX books work)
– the KFX books which do not work for me show up in Calibre as filetype KFX-zip
– always use the newest Calibre and Plugins for KFX
As I have tested quite a lot, sometimes it helps (regardless wether Windows or Mac), to configure the OS for a new user and start with fresh installs, logging in with your Amazon Account.
Also, if you are used to copying the files from the Kindle to your Hardisk before proceeding, you should not copy single files, but simply everything, all directories. Reason I say this, I have to Kindle eInk, one for US-bought books, one for German-bough books, for some reason, from the US Kindle I can simply copy the whole ebook directory and import with Calibre KFX from there, with the German one, I need the other directories (tried to look into the source to check which ones, but could find them), like system etc from the Kindle. If you import directly from the Kindle with Calibre, it should find all needed files, no matter where they are.
These files are put together with the KFX import plugin into a single file for Calibre. At what point the DeDRM happens if before or after I do not know.
Hope this helps. Else post a debug log from a fresh import which did not remove the DRM.
sorry typed too fast, some words and characters are missing, to the point some logic is left on the floor, sorry.
:-),
– “I have 2 Kindles”
and
– “could not find the directories”
The other stuff should be clear even with the typos, hopefully.
Well, I’m not entirely sure how to do the debug bit, being honest.
It’s just so weird to me because my last computer did this just fine, but now on transferring to this one, it seems to not want to work.
As for importing, I’m actually doing this via Kindle for PC, files are all AZW. Just no luck.
You have calibre with DeDRM and Kindle for PC on the same computer and user? The books were downloaded with that installation of Kindle for PC?
If still no luck, here’s how to post a debug log:

Thanks for the instructions.
Weirdly enough, however, when I went to try it, I ran it once more for giggles, and… the conversion actually worked. I have no idea why but I am ecstatic.
Thank you so much for trying to help though!
Sometimes all it takes is restarting calibre.
Hi, I really love this software for archival purpose from Kindle. But seems i found that conversion from KFX to ePub format didn’t convert the image in highest quality. I have KFX file around 19 MB but converted ePub only 1 MB in size. The images converted to lower quality. Could anyone help me? Did I something wrong? Calibre Portable used, DeDRM and KFX Input plugin installed. I’m pretty sure KFX is DRM free since conversion success.
Thank You
I suspect that the problem lies in your calibre conversion settings. In the “Page setup” tab the “Output profile” should be set to “Tablet” in order to not have calibre downsize images during conversion.
Thank you very much, ‘Tablet’ profile do the tricks.
Hi, I bought book from HPE press, and its locked by DRM in ADE. calibre plugin cant remove drm. and I cant open “DeDRM_App for Windows” on Windows 10. I installed ActivePython-2.7.14+pycrypto-2.6.win-amd64-py2.7 but “DeDRM_Drop_Target” didnt open.
Any options?
Hi, Maybe you can take a look here regarding ADE: https://github.com/apprenticeharper/DeDRM_tools/blob/master/FAQs.md#i-registered-adobe-digital-editions-30-or-later-with-an-adobe-id-before-downloading-but-my-epub-or-pdf-still-has-drm
Hi, I opened new buyed book with ADE 3.0. ADE 2.0.1 didnt see new URLLink.acsm
Can you read your book with ADE 2.0.1 authorized with your Adobe ID?
no I cant open acsm file in ADE 2.0.1. its give me error “Unable to download” error getting licemce, Licence server communocation problem: E_ADEPT_CORE_DECRYPT_LICENCE_KEY. Maybe this error cause I opened first in ADE 3.0
but I can open acsm file in ADE 3.0 and 4.5 without problem, but cant delete drm with calibre plugin (i downloaded 6.6.0. plugin loaded it in calibri, then reexport book in calibre and double-clicked to book in calibre, but calibre give me error “the book is locked by DRM”. As I know Calibre plugin should automatically delete DRM and open book doesnt?
Sounds like it probably has the newer Adobe DRM. As far as I know, no tool has been created which can remove this DRM yet.
As you have bought the ebook, I would try to download it with the old DRM, there should be a way to that (using an older Adobe Digital Edt., or Sony Reader).
If not, complain to the merchant that you cannot read the ebook on your device, it is unusable. If they fail to help by providing a readable copy, raise hell and give it back with demanding your money back, threatening that they lose you as a costumer.
This (for me) is the main reason why Amazons Kindle format is so popular. It works, DeDRM works, and they take ebooks back (within a reasonable time and if you do not do it too often), give you your money back and value the costumer.
Having said that, I still buy epubs and use them on a Tolino epos, DeDRM them , store them with Calibre and could convert them to Kindle (Mobi, AZW) to use there. If and when Amazon offers a different eReader, I can switch back, the Voyage is ok, but could should have been updated now (waterproof, more memory etc.).
From what I understand, once you download a copy with the newer DRM, you will always get the new DRM on new downloads of that book. The only way to get the older DRM then is to delete the book from your account and buy it again. As Ingo suggested, you might be able to complain and get the bookseller to reset the book at no additional charge. But it’s possible they’re not using the older DRM. In that case, you wouldn’t be able to download any books from them with ADE 2.0.1 at all — or DeDRM them.
It all depends how customer-friendly they are. Given that it is a specialty shop for technical manuals and information ebooks, there may be little chance getting the ebook elsewhere, so even getting the money back is no solution, if you cannot buy the ebook in a different shop.
From their FAQ they do not specify ereader as an eInk device, but they rather think a tablet (Android, Kindle Fire) or an iPad counts as an ereader. Which due to the display difference it is not, for me.
But that is beside the point. Are there eInk devices to buy which have support for the new Adobe DRM? The few devices I can buy in Germany (Tolino and a few others) do not support it yet – a firmware update could change that, though.
tl;dr no real solution, sorry for that.
No idea if any E-ink ereaders currently support the new Adobe DRM. That’s a good question.
I installed Adobe Digital editions with WINE. I do not see any .der files in the appropriate folders. How do I find the keyfiles/adobe digital editions keys so I can plug them in to the DeDRM plugin for calibre?
Post a log and we’ll see what’s going on. With Linux you sometimes (often?) have to run the key script manually. In which case, you can specify where it gets saved.
Ok after reading the faq … https://github.com/apprenticeharper/DeDRM_tools/blob/master/FAQs.md

When I bring up DeDrm 6.6.0 on my Linux box, click Adobe Digital editions and click the green plus sign, I see “The default encryption key for Adobe Digital Editions could not be found.” The list of keys next to the buttons is empty. The book comes from a bookstore chain in continental Europe.
I am working in parallel on a Windows box, trying to find the keyfile there, but it is not working either. I should never have given someone money for an eBook which did not clearly state ‘no DRM’!
As I thought, you’ve got the same problem I’ve seen here with a lot of Linux setups. See this part of the log:
DeDRM v6.6.0: Command line: ‘WINEPREFIX=”/home/ABC” wine python.exe “/home/ABC/.config/calibre/plugins/DeDRM/libraryfiles/adobekey.py” “/home/ABC/.config/calibre/plugins/DeDRM/libraryfiles/winekeysdir”‘
wine: cannot find L”C:\windows\system32\python.exe”
When it tries to run the key script, it can’t find Python. You do need Python and PyCrypto installed under Wine. You should be able to run the script manually and import the retrieved key into the plugin customization.
But if you’ve got a Windows setup, you should be able to export that key from calibre/DeDRM on the Windows machine and import it to calibre/DeDRM on the Linux setup — as long as both ADE installations are authorized with the same Adobe ID. The Windows setup should automatically retrieve the key if both ADE and calibre are on the same machine and user. It should be ADE 2.0.1 authorized with your Adobe ID and latest calibre with DeDRM. You need to be able to read the DRM book in ADE.
I installed both Adobe Digital Editions and Calibre with DeDrm 6.6.1 on a windows box and was able to create a keyfile and open the epub in Calibre. When I copied the keyfile to my Linux box and used “add from file” under Calibre -> Preferences -> Plugins -> DeDrm, I still get the message about DRM when I try to open the same epub in Calibre on the Linux box.
It also looks like the original file still has DRM, so I can’t just load the new version onto my Tolino and avoid having to give my ADE password again and again.
Definitely sounds like you’ve got it working on Windows. Not sure why the key won’t work on Linux. Did you restart calibre after importing the key and before adding a book?
For some reason I have a .AZW file that this can’t decrypt.

Ah Ha, that did it! Thank you!
Is DRM completely removed from that particular file within Calibre now? Did it strip the DRM while importing?
Yes, DRM is removed during import. But these tools don’t remove anything else that may identify the file as coming from your account (sometimes called “social DRM”).
Ok, That’s fine.
Thanks again!
Used the tool today on my Amazon-purchased e-ink files and it worked like a charm. However, when I try to side-load the new files (mobi) onto my paperwhite they don’t show up. Calibre says they’re in the device library but I can’t see them. Kindle issue or the files?
Make sure you’re looking at the Downloaded tab of your library and have “All Items” showing.
How did you copy the ebooks to your Kindle?
Maybe manually?
Calibre automatically puts them in the correct directory, under a folder with the author-name (else “unkown” or something like that is used).
The directory is :/documents .
Just tested it with a Kindle, and copied an ebook manually in the main (root) directory of the Kindle.
It does not show up.
Also another reason might be the sort order of the books, if you have a lot of books on the Kindle. Take note of the title and search for it, or page through the books lists, but that might take a while.
I figured it out. Removed the files from my device directory through Calibre, re-converted them to AZW3 rather than Mobi, then transferred again and it worked. Have done MOBI many times before so no idea why it didn’t work this time. Thanks for the suggestions though!
Under Docs instead of Books?
I have it set to show all files so i’m not sure how it categorizes them.
I’m sure someone at MobileRead would know why.
