EPUB
EPUB is an open standard format for ebooks, based on XHTML and designed so text reflows to fit any screen. It is supported by most ebook readers, tablets and phones, and is the format you find in most online bookstores. Because the text adapts to the device, reading stays comfortable on small and large screens alike.
Use EPUB when you publish an ebook or a long document meant to be read on e-readers, tablets or phones. Its reflowable text makes it the right choice when readers should be able to adjust font size and screen.
