EPUB converters
EPUB is the open standard for e-books, first published by the IDPF in 2007 and maintained by the W3C since 2017. Apple Books, Kobo, Google Play Books and most library and e-reader apps open it. The text reflows to fit the screen and the reader's chosen font size, so an EPUB has no fixed pages.

What to know about EPUB
- An EPUB is a ZIP archive of XHTML pages, CSS, images and fonts, plus a package file (.opf) that lists them.
- The spine in the package file sets the reading order. EPUB 2 (2007) and EPUB 3 (2011 onwards) are both common.
- Books with DRM, such as Adobe ADEPT or Apple FairPlay, are encrypted and only open in the apps that hold the key. Kindle books use Amazon's own formats, not EPUB.
- Fixed-layout EPUBs, used for comics and picture books, have set pages instead of reflowing text.
