Calibre 0.8.22 + DRM Removal Plugin

Calibre, a free and open-source e-book computer software application suite which runs on multiple platforms, allows users to manage e-book collections as well as to create, edit, and read e-books. It supports a variety of formats (including the common Amazon Kindle and EPUB formats), e-book syncing with a variety of e-book readers, and conversion (within DRM restrictions) from different e-book and non-e-book formats.

Calibre supports many file formats and reading devices. Most e-book formats can be edited, for example, by changing the font, font size, margins, and metadata, and by adding an auto-generated table of contents. Conversion and editing are easily applied to appropriately licensed digital books, but commercially purchased e-books may need to have digital rights management (DRM) restrictions removed. calibre does not natively support DRM removal but may permit DRM removal after the installation of plug-ins with that functionality
