«Calibre is an e-book manager. It can view, convert, edit, and organize e-books in all the major formats. It also can communicate with e-reading devices, extract metadata for your books from the internet, download newspapers, and convert them into e-books for easy reading. It’s cross-platform and runs on Linux, Windows, and macOS,» explained the project’s creator, Kovid Goyal.

«It’s been just over a year since the release of Calibre 7.0. A lot of work has been done on Calibre in the past year. The key new features include a new neural engine for more realistic text-to-speech and reading aloud, as well as built-in support for the Kobo KEPUB format,» the project team shared.
