EPUB is an ebook file format with the extension .epub that can be downloaded and read on devices like smartphones, tablets, computers, or e-readers. It is a free and open standard published by the International Digital Publishing Forum (IDPF). The term is short for electronic publication and is sometimes styled ePub.

By using HTML5, publications can contain video, audio, and interactivity, just like websites in web browsers.
