The EPUB (or Electronic Publication) is the free and open format standard in the ebook industry. This standard is maintained by the International Digital Publishing Forum (IDPF), a non-profit organization of the world's largest publishers and technology enterprises, of which Flipside is a member.

The EPUB format runs on most e-Readers and devices except the Amazon Kindle e-ink readers. Currently, there are two popular versions: EPUB 2.2 and EPUB 3.
