Step 4, Remove DRM from eBooks.

Drag all books to calibre, all done!


Method 2, Python Scripts.

All eBook DRM Removal tools are Python Script.

Calibre plugins are also python scripts, but not GUI.

Here are the python scripts have friendly GUI.

DRM Removal tools

For running Python Scripts, you need install Python at first.

Download Python python-2.6.2.msi


Pycrypto is DRM Encryption and Decryption module, download pycrypto-2.1.0.win32-py2.6.exe, all the DRM tools include this module, so, you must download and install it.

For mac user, you need to search Python and Pycrypto online.


After python environments prepared, download and run DRM Removal tools (for Windows, for Mac):

Remove DRM from Adept ePUB

Run ineptkey_v5.4.pyw to generate Adept key(adeptkey.der).

It requires you have install Adobe Digital Editions and authorized with your Adobe ID.

When adeptkey.der generate succeed, run ineptepub_v5.6.pyw, input Key file, Input file and output file, then click "Decrypt".

All done.


Remove DRM from Adept PDF

Run ineptkey_v5.4.pyw to generate adept Key, the same as remove drm from adept epub.

keep ineptpdf_v7.11.pyw and ineptkey_v5.4.pyw in same directory, it's easy to find adeptkey.der file.

Click "..." to browse file, then click "Decrypt", all done.


Remove DRM from Nook ebooks

Note: not all ebooks purchased on B&N are protected by Nook, when you purchase ebook on B&N, here are two methods need you to choose, Adept DRM and Nook DRM. If choose Adept DRM, use Remove DRM from Adept ePUB method, if choose Nook DRM, follow as below:

Run ignoblekeygen_v2.3.pyw, input your Credit Card Number and Name(Billing card and name) to generate nook key, the scripts just generate nook key file, not record any information.

Run ignobleeput_v3.4.pyw, choose nook key file and input output file, click "Decrypt", if failed, please regenerate your nook key file.



Remove DRM from Kindle AZW/Mobi/Topaz/Prc books

View the GUI, you may confused, it's so hard to use, please pay more patience.

PID: any ebooks has one PID binded, it's hard to find. Search it on Google.

Kindle Serial Number: To confirm which Kindle you have, look at the serial number on the back at the bottom (for Kindle 1, it's under the back cover). You should also be able to find it on the Kindle packaging. Since firmware 2.5, it is also shown in the Settings page on your Kindle. This is also the only place you'll be able to check your S/N on a Kindle 3. View Wiki.

Kindle.info: It contains all PIDs, when Kindle for PC/Mac installed, the file will be created.


If you transfer books from Kindle Reader, then input Kindle Serial Number, if you use Kindle for PC/Mac to sync the books to computer, then you need to find PIDs or Kindle.info.


If you can't find the PIDs and Kindle.info or have some trouble with this script, please use the Method 3 as below.


Method 3, DRM Removal Shareware.

I suggest you use free DRM Tools, but if you have trouble, then you can choose the Shareware Any DRM Removal(for Windows, for Mac):

Any DRM Removal


Note: all the tools requires you can read the ebooks on computer at first, it helps you backup ebook files belong to you, not others.

Hallo, Epubee worked beautifully until yesterday then "Couldn't Retrieve key from ADE install" appeared and no more files were unDRMzed. Tried installing Calibre plugin, still not removed. Just ran the script you recommended and this is the output. I would really appreciate your help!

For decrypt Adept ePUB & PDF, please make sure all the ebooks are download by the current version of Adobe Digital Editions!

Please try to delete all the books and redownload them again.

Likewise. Neither ePUBee not Calible work. They did but not now. Any suggestions?
04/8/2013 20:04:47

For decrypting ebooks, plesae make sure the ebooks are purchased by yourself, and make sure all the books are download the the current version of official software, and you can read all the ebooks on Kindle4PC/Nook4PC/Adobe digital editions.

If you meet problems, please delete all the ebooks and sync all books to pc again.

Have downloaded the plugin zip file but when I go to preferences in Calibre, I am only given "get plugins to enhance calibre" after which it provides a list of installed, not installed etc, but no option to install from file, so how do I import the drm removal?
04/13/2013 08:37:45
You have to click on Preferences then Change Calibre Behavior the plug in is at the bottom

after installation of "ineptepub" I'm not sure how to run the plugin. For sure I have no *.der files and don't know how to generate them.

Any advice is welcome.

I have downloaded and installed drm files as per Alf's Blog, but when I import books the drm is not removed. Tried first with batch of books, then deleted and tried with a single book but still no good.
checked the preferences - plugins - file type extensions and Inept Epub DeDRM (0.1.7) is there and does not need customising.  I installed Calibre 10 days ago so I have the latest version.
Any assistance would be appreciated as I have removed all 900 books until I sort htis out. (btw tried eePubee but unless I deconstruct all the folders (358) it will not run DRM)

Have exactly the same problem as Booklover.
Plugins seem ok but whenever I add a awz/awz3 file to calibre, the drm is not removed. When I try to view or convert to mobi I get the 'protected by drm' message - can't do anything :(

kindle solution OK and great. thank you
12/8/2013 13:57:34

Can u help me?
The plugin is installed and activated but I cannot configure it, Calibre says it is not needed

I cannot convert the DRM epub to kindle!

06/15/2014 05:24:43
Finally rid of Adobe Digital Editions on purchased books. Followed python scripts method, carefully to the letter. Had to go back to 2.6.2, neither 2.7 or 3.4 versions worked.
Many thanks for this...

I installed the Calibre plugin, and there it is just the same as in the screenshot. When I double-click, it says "calibre, version 2.1.0
Plug-in isn't customisable: Plug-in: Inept Epub DeDRM does not need customisation". The plug-in is 0.1.7, calibre is Win32. And converting DRMed files fails: "Cannot convert... This book is locked by DRM". Any ideas?
09/4/2014 23:16:23

Thank you for the great job. Unfortunately I do not have a kindle serial number to put in  as I do not own a Kindle device and I am using the Kindle-Windows version on PC. Does this mean that the Callibre method wouldn't work?
