About EPUB files
the open, reflowable ebook standard
EPUB is the open ebook standard, now maintained by the W3C. An EPUB is a ZIP of XHTML pages, CSS and images, so the text reflows to fit any screen.
Ebooks from most stores and libraries, read in Apple Books, Kobo and Google Play Books, and on Kindle through Send to Kindle since 2022.
