Then there was I♥CABBAGES who released DRM removal for Adobe ebooks.Īnd then there were many others who improved the tools, including decrypting and decoding Amazon's Topaz and decrypting KFX files.Īnd the people who worked on decrypting Kobo books from the Kobo app.

Or was Apprentice Harper involved all along? (Don't know the history.)As I recall, the first was 'The Dark Reverser' who release a python script for removing DRM from Mobipocket ebooks. I feel like I need to find some way to thank Apprentice Alf for all his work.

Convert the book from AZW to MOBI ( or any other format).Thanks for the clarification I inadvertently added an extra layer of confusion.

Download a Kindle ebook to your PC via Kindle App.

Install the latest DeDRM 6.6.1, you can download the plugin files here.

Install the KFX Input plugin, by following the guide here.

This is just to make sure that Calibre can support whatever plugins that come along

Update the Calibre to the latest version.

Anyway Amazon turns on auto update by default.

Update the Kindle App to the latest version.

Thanks to the work of Apprentice Alf and some other people, DeDRM 6.6.1 can decrypt Amazon KFX format! We have tested the solution and it really works!. Won’t it be better if someone just make the DeDRM works with the latest KFX formats? And finally, the DeDRM 6.6.1 is now here… Those techniques are not straightforward, and require technical expertise to properly configure your software.

Never upgrade to later version of Kindle App, stick with 1.19.

The post goes on to suggest how one can workaround this issue. These books will appear in a subdirectory of the “My Kindle Content” folder, will import into calibre as “AZW” format, and will fail to convert with the error: “KFXError: This is an Amazon KFX book. The direct consequence of this action is that Calibre ( with DeDRM plugin) that many people love to use, can no longer strip the DRM off from Amazon ebooks, and can no longer convert the Kindle ebooks to MOBI or EPUB format.

Starting from Kindle App 1.19 onwards, Amazon changes the format of the downloaded Kindle ebooks to KFX format. Use Calibre to remove DRM only when you are certain that you have the rights to read the books anywhere and in however formats that you want. Although it is not wrong to tell people how to remove the DRM( ie: this post is not wrong), we are not condoning piracy: we do not recommend you strip off the DRM and share/sell the books in violation of copyrights laws.
