Calibre

Calibre is the free desktop program most people use to keep an ebook library in order and copy books onto a reader. With the Libra Colour it works over a USB-C cable out of the box, and wirelessly once you add a plugin.

What to know before you start

• The Libra Colour reads EPUB directly. You do not need to convert anything for a normal EPUB to work.
• KEPUB is Kobo’s own version of EPUB. It adds better in-book page numbers and reading statistics on Kobo devices. Calibre can send books as KEPUB automatically once you turn that setting on — it is optional, and covered as an aside in the guide below.
• Sideloaded books sit next to store books. Anything you send with Calibre appears in “My Books” on the Kobo home screen alongside books bought from the Kobo store.
• Keep your originals as EPUB. Convert only when a specific device needs it, and keep the EPUB. Every conversion can introduce small formatting errors.
