# [Guide] How to remove DRM
Refer to [Wiki Page](https://github.com/apprenticeharper/DeDRM_tools/wiki/Exactly-how-to-remove-DRM)
# calibre 5.0
Yes, we know that the plugin doesn't work with calibre 5.0. It will eventually, but there's a lot of code to be translated that does complicated stuff with bits and bytes that must be converted by hand. It'll take a while.

DeDRM tools for ebooks
This is a repository that tracks all the scripts and other tools for removing DRM from ebooks that I could find, committed in date order as best as I could manage. (Except for the Requiem tools for Apple's iBooks, and Convert LIT for Microsoft's .lit ebooks.) This includes the tools from a time before Apprentice Alf had a blog, and continues through to when Apprentice Harper (with help) took over maintenance of the tools.
This is a repository of all the scripts and other tools for removing DRM from ebooks that I could find, committed in date order as best as I could manage. (Except for the Requiem tools for Apple's iBooks, and Convert LIT for Microsoft's .lit ebooks.)
The individual scripts are now released as two plugins for calibre: DeDRM and Obok.
The DeDRM plugin handles books that use Amazon DRM, Adobe Digital Editions DRM (version 1), Barnes & Noble DRM, and some historical formats.
The Obok plugin handles Kobo DRM.
Mostly it tracks the tools released by Apprentice Alf, athough it also includes the individual tools and their histories from before Alf had a blog.
Users with calibre 5.x or later should use release 7.0.0b2 or later of the tools.
Users with calibe 4.x or earlier should use release 6.8.0 of the tools.
Users should download the latest zip archive.
Developers might be interested in forking the repository, as it contains unzipped versions of those tools that are zipped to make the changes over time easier to follow.
For the latest Amazon KFX format, users of the calibre plugin should also install the KFX Input plugin from the standard calibre plugin menu. It's also available from the MobileRead thread here: https://www.mobileread.com/forums/showthread.php?t=291290
Note that DRM can only be removed from KFX format files downloaded with Kindle for PC/Mac 1.26 or earlier. Amazon changes the DRM for KFX files in Kindle for PC/Mac 1.27 and later.
I welcome contributions from others to improve these tools, from expanding the range of books handled, improving key retrieval, to just general bug fixes, speed improvements and UI enhancements.
I urge people to read the FAQs. But to cover the most common: Use ADE 2.0.1 to be sure not to get the new DRM scheme that these tools can't handle. Do remember to unzip the downloaded archive to get the plugin. You can't load the whole archive into calibre.

Do remember to unzip the downloaded archive to get the plugin (beta versions may be just the plugin don't unzip that). You can't load the whole tools archive into calibre.
My special thanks to all those developers who have done the hard work of reverse engineering to provide the initial tools.
