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.

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.
Hello,
I’ve installed the latest version of the DeDRM plugin to Calibre 5.18.0. I recently transferred a bunch of older book from a previous kindle (registered to another account I have no access to) to my computer, then to my kindle paperwhite. I saved the serial number of my paperwhite in the plugin’s customization window, however I wasn’t sure if the serial number is supposed to be from the kindle the book is going to or the kindle it was originally licensed to. I am unable to remove the DRM from my older books (awz3, not kfx). Before I post my log, I wanted to ask if there might be an issue with the serial number I used just in case. I figured there might be something fishy there!
Thanks in advance for any help!
The DRM which needs to be removed will be associated with the device or app they were downloaded with. After DRM is removed, it can be read on whatever you want. So you need the serial number the books are from. Not the one they are going to.
That is correct, but it would also be easy to simply put both (or more) Kindle serial numbers in the DeDRM-Plugin Settings, even if one of them is not needed yet.
Also, as a side effect, the transfered books from the old device should not work on the new device, imho
– or the ones that work do not have DRM anyway.
If there is a problem using a different Account for the old Kindle, the books can also not be downloaded from Amazon again.
I posted a message recently with my own error message I received from an attempted installation. I’m logged in with my WordPress credentials but I haven’t seen it posted. Do I need to repost? I was afraid to do it again because I didn’t want to seem like I was spamming the comment section. Thanks!
This time when I hit the post button, it sent. I’m not sure what happened the last time.
This is the error message I get when I attempt to install the plugin. I’ve been using this plugin for quite a while but I reformat my hard drive around once a year or so to get rid of bit-rot and such. It was installed on this computer before I re-installed Windows, so it’s not like I’m new to the plugin. Still, this is the error I get. Thank you for any input!

You need the latest version of the plugin for calibre 5.0. The one you’re trying to load is written in Python 2 and will only work with calibre 4.x (and earlier).
Hi there,
I’ve just freshly installed Adobe Digital Editions 4.5, Calibre 5.23, and the DeDRM plugin 7.2.1.
I’ve used older versions successfully in the past, so I think I’ve got the method down. XD However, a book imported by .acsm into Digital Editions and then to Calibre, but Acrobat is still saying “… The security plug-in requires by this command is unavailable” when I try to open the file from the Calibre library.
Here’s my debug data:

DeDRM 7.2.1 still needs some work for Adobe PDFs. Try calibre 4.23 and DeDRM 6.8.1.
My undying appreciation! That worked!
I am having trouble getting mine to convert.
I am running Windows 10.
The ebook was purchased and downloaded from Google Books. I am trying to get them onto my Kindle.

Hopefully that’s everything needed. This is my first time trying to use this, so I could easily be doing it wrong…
Looking at your log snippet, it looks as if you are trying to import The_Bridge_Kingdom-epub.acsm from your downloads folder. This is not an ebook but rather an Adobe Content Server Message file which tell ADE how to download the file and what rights you have on it. You will need to open that file with ADE to actually download the ebook. If you do not already have ADE installed, you will need to install and register it.
Thank you! I did have it installed and loaded the book with it, but couldn’t figure out what to do from there (or why it was even necessary…). Turns out they’re in my documents folder, and they work just fine! Appreciate the push in the right direction lol!
Could anyone help me figure out what I need to do? I’m using a Windows 10 PC and the book is downloaded from Amazon. I’m trying to get it converted to a pdf so I can read it more easily zoomed in (text is super blurry zoomed into the original file).
This post explains how to get a file from Amazon that can be decrypted: https://www.mobileread.com/forums/showthread.php?t=283371
Once you have that, you should be able to decrypt and convert with calibre and the DeDRM plugin.
“converted to a pdf so I can read it more easily zoomed in (text is super blurry zoomed into the original file).”
This reads to me like you are already reading a PDF (inside an Amazon eBook container) – and with scanned pages.
This is a guess, so I maybe wrong, but if this is the case, and you manage to strip DRM, and convert it to PDF, this will not solve your problem, you still look at images, which will blurr, when zoomed. OCR might help, but wether that is even possible?
yes, my thought was that it may be exactly as you described.
re using OCR: back in the Groklaw days I processed some of their legal documents (on Linux), which were primarily scanned images inside a PDF like this:
1. use pdf2tiff to create tiff images.
2. use some custom scripts I had hacked together to run early releases of Google’s tesseract OCR on those tiff images.
3. the results, of course, still required cleaning up due to the inevitable ‘scanos’. a lot of work was involved.
TY for letting us responsibly use our own epubbooks. I just got a new reMarkable ink tablet and this will make it actually useful.
I am trying to archive my Nook magazines from B&N. I get the epub from Nook for PC and can view, with that epub, the magazine in “page view”. When the epub ends up in Calibre, however, it’s only in “article view”. I heard that the page view is just a series of images which would have to be included in the original epub file.
I’m wondering if the DRM removal tools also strips the “extra” pictures from the epub since they’re not technically part of the epub format. Is that possible? If so, is there a way to prevent that? Since I can’t get into the epub until after it’s been de-DRM’d and imported into Calibre, I can’t easily verify if it’s pictures of what.
G
ePubs are a zip file. Just unzip the epub and see if the page images are in there.
When does DRM come into play with epubs, then?
The files inside an ePub can be encrypted. But you mentioned being able to view the ePub in calibre, so there either was no DRM, or you’ve successfully removed it.
I’ve successfully removed it — and that’s when I think the images (that would look like they’re extra to an epub program) get removed. I was wondering if my guess is correct and if there were a way to prevent that from happening.
Have you unzipped the de-drmed ePub? (If not, do so and check whether the images in there somewhere)
Is the size of the de-drmed ePub significantly smaller than the ePub with DRM? (If so, perhaps the images did get stripped. Try unzipping the DRMed ePub – images sometimes aren’t encrypted.)
Yea, after you last message I looked. The images were there (yay!) and I was able to read them. And yes, the calibre epub is notably smaller. So, is there a way to get the DRM app to not strip the images?
The DeDRM app does not strip images. If you import the original epub into calibre and check, the images should be there. I just checked on two epubs and the images in the original epub and the deDRMmed epub were close to identical in size (the ones with DRM could not be opened since they are encrypted). OTOH, if you are using calibre to convert epub to epub (or any other format), that’s a whole ‘nother can of worms and outside the focus of this blog.
Ok… time to explore some more. TY for the responses.
Hi, I tried importing a book recently downloaded. I followed all instructions and have Calibre 5.23 installed along with Kindle for PC 1.30.0 (59056). Directly after installing the programs I could download books from Amazon and was able to add them to Calibre without any problems, but when I tried again today the downloaded books were placed in a folder again and when I tried importing the .azw file I got a ‘DRM’ message. This is the information from the log:
