Technical details EPUB is the most widely supported vendor-independent XML-based (as opposed to PDF) e-book format. An EPUB file is a ZIP archive that contains, in effect, a website-including HTML files, images, CSS style sheets, and other assets. It also contains metadata. EPUB 3 is the latest version. By using HTML5, publications can contain video, audio, and interactivity, just like websites in web browsers.
