What is EPUB file?

An EPUB file is considered a digital e-book saved in the EPUB format (an open format of digital books with XML-based publishing). The format is standard in the digital publishing environment, used by publishers/consumers to store book text, chapter links, covers, images, and other ebook elements.

Supporting programs with hardware devices can view EPUB files.

Additional data

The EPUB format is built on three open standards that are supported by the International Digital Publishing Forum (IDPF):

  • Open Publication Structure (OPS), which defines content markup.

  • Open Packaging Format (OPF), which describes the structure of an e-book.

  • Open Container Format (OCF) packages each e-book file into a compressed format.
