How we check software

Manage, convert and edit your e-book library

Calibre is a free e-book manager that organises your library, converts between formats such as EPUB, MOBI and PDF, and sends books to many e-readers. It also includes a book viewer and a built-in EPUB editor, which makes it useful to self-publishing authors.

The interface shows its age and has many options, but it remains the standard free tool for serious e-book collections.
