Remove Kindle DRM - Jailbreak version
I could give an introduction about ownership of digital content and why it is important to have your own books and be able to read them on the device of your choice. However, I won't do it in this post. I'll just show you how to remove DRM from Kindle books in 2026.
I don't encourage piracy and the distribution of copyrighted material. You should use this tutorial only to read your books on other devices/mediums.
Prerequisites
This method requires a jailbroken Kindle. If you don't have a jailbroken Kindle device, this tutorial won't work.
If you haven't jailbroken your Kindle yet, follow the official guide at the Kindle Modding website.
Step 1 - Connect your Kindle to your computer
Connect your Kindle to your computer using the USB cable.
Step 2 - Download the DeDRM Kual Extension and Calibre Plugin
Go to the GitHub repository of the DeDRM plugin and download the file "kfxdedrm_kual.zip" from GitHub releases.
For the Calibre Plugin, search the same GitHub release page and download the DeDRM_tools.zip file. The version I have installed in this tutorial is 10.0.24, but I recommend always downloading the latest.
Step 3 - Install the DeDRM Kual Extension
Unzip the file "kfxdedrm_kual.zip" and copy the folder "kfxdedrm" into the folder "extensions" in your Kindle's root directory.
Step 4 - DeDRM your books
Disconnect your Kindle from your computer and open KUAL on your Kindle. Expand the program "DeDRM KFX files". Inside, you'll see a few options; select "Dedrm all KFX". It will scan all your Amazon books in the Kindle, and it might take a few minutes depending on the number of books you have.
While the plugin is scanning your books, proceed to step 5.
Wait until you see the message "DeDRM all done." before proceeding to Step 6.
Step 5 - Install the DeDRM Plugin in Calibre
The Calibre version I have installed for this tutorial is 8.10.0. You can find this specific version for download here: download Calibre. It might work with newer or older versions, but I haven't tested them.
Step 5.1 - Install the KFX Input Plugin
Go to Preferences -> Preferences -> Plugins -> Get New Plugins and search for the plugin 'KFX Input'. Install it. (don't restart Calibre yet)
Step 5.2 - Install the DRM Calibre Plugin
There are many tutorials on the internet on how to install this plugin, so I won't repeat them here. It is a very straightforward process. I recommend following this tutorial, and you can use the file downloaded from Step 2.
Restart Calibre after the installation of both plugins.
Step 6 - Add your books to Calibre
Connect your Kindle back to your computer, then open the folder "dedrm" in your Kindle's root directory. You should see all the books you have on your Kindle inside this folder with the "kfx-zip" extension. Select all the files and drag them into Calibre's interface.
Now you have all your books in Calibre, and you can do whatever you want with them.
Step 7 - Convert your books to EPUB
Select all of your imported books and click on the bulk convert button. It will open a popup window, and on the top right corner, you will see the output format. Select "EPUB" from the dropdown menu.
Then hit "Ok" and wait for the conversion to finish. You should see the progress in the bottom right corner of Calibre.
Once the process is finished, select all books again, expand the "Save to disk" button, and choose "Save single format to disk..."
Now you have all your books in EPUB format, and you can do whatever you want with them.
