What is a KEPUB?

KEPUB is Kobo’s enhanced version of the EPUB format. It adds the page-tracking markup Kobo devices use for fast page rendering, accurate “time left in chapter” stats, proper pagination, and reliable bookmarks and highlights. A normal EPUB works on a Kobo, but converting it to KEPUB unlocks the full reading experience.
