The easiest way to strip DRM from Kindle books (and Barnes and Noble, Adobe Digital Content, etc) is with the free ebook software Calibre, DRM removal plugins, and a copy of the Kindle desktop software (PC/Mac). These directions are for Kindle, but will work with Barnes and Noble, Adobe Digital Editions, and older formats. Here’s what you need to do:P
- Download Calibre, the the plugins, and the Kindle Desktop software.
- Unzip the contents of the plugin directory.
- Open up Calibre and click on “Preferences.”
- Navigate to “Plugins” under the “Advanced” section.
- Click “Load Plugin from file,” and select K3MobiDeDRM_v04.5_plugin.zip from the directory you just unzipped.
- Load up the Kindle app on your Mac or Windows computer and download all your books from Amazon.
- Navigate to either C:Users[your username]DocumentsMy Kindle Content on Windows or [your username]My DocumentsMy Kindle Content on Mac.
- Your books aren’t named in any meaningful way, so just drag all the *.azw files into Calibre.
- After a short wait (depending on the size of your library), Calibre will finish importing the books. Now you have a DRM-free backup of all your books on your computer.
It’s a little convoluted, but once you get the hang of it, Calibre is a solid way to backup all your purchased ebooks.P
