What is a EPUB file?

Electronic publication, to every bibliophile known as EPUB file, is one of the most popular formats used for storing e-books and other types of content. It’s an open XML-based format that provides a standard digital publication for both publishers and consumers. This type of file format is based on three open standards maintained by the IDPF. The first one is OPS (Open Publication Structure) that defines the content markup. Next, there’s OPF (Open Packaging Format) that describes the e-book structure. And the third one is OCF (Open Container Format), which packages all files together in a compressed format. Every EPUB file can be opened with Apple Pages, Adobe Digital Editions, Apple Books, Google Play Books, File Viewer Plus, FBReader, etc.
