A pre-release of the DeDRM plugin only (v7.0.3) is now available.  This release REQUIRES calibre 5.x which utilizes Python 3 for plugins. Since this is the DeDRM plugin only, DO NOT unzip the downloaded file.  Load the entire zipped file as is into calibre 5.x.  To leave a comment, see this post: DRM Removal Tools for eBooks. can be downloaded from

Pre-Release Notes

This has more changes to It should now handle most PDFs from ADE, on both PC and Mac.

This change now also fixes reporting of metadata in some PDFs, and may fix other problems. This change will be back-ported to the 6.x branch in due course. (Keywords in PDFs should not have spaces, but an encoding of %20 was getting converted into a space on reading in the PDF, and not converted back again. This seems to be a long-standing bug.)

I think I’ve also updated the version number correctly this time. 🙂
