A collection of Python scripts packaged as calibre plugins (DeDRM and Obok) that remove DRM from ebooks, covering Amazon, Adobe Digital Editions, Barnes & Noble, and Kobo formats. The original project is no longer maintained; users are directed to noDRM's fork for updates.
Use cases
- remove DRM from Kindle ebooks
- decrypt Adobe Digital Editions books for calibre
- strip Kobo DRM with the Obok plugin
- convert purchased ebooks to DRM-free files
- unlock Barnes & Noble epub books
When to choose
- you use calibre 5.x+ and need DRM removal for Amazon, Adobe, B&N, or Kobo books
- you want a well-known, historically reliable set of DRM removal plugins
When to avoid
- you need support for the latest Amazon KFX DRM changes - use the actively maintained noDRM fork instead
- you use Apple iBooks (Requiem) or Microsoft .lit formats, which are excluded
- you want a maintained project with ongoing bug fixes
