    Calibre is for managing ebook libraries, converting ebook formats, and reading ebooks. The DeDRM tool can be installed as an unofficial plugin for Calibre for a specific purpose, but it is not an alternative to any of Calibre's major functions.

    Focused on reading, not library management. Can't convert between formats.
