What is EPUB file format?

The EPUB file format is a free and open standard for digital books and other digital documents. It was developed by the International Digital Publishing Forum (IDPF) to provide a consistent format that can be used across all digital reading devices.

EPUB also includes Digital Rights Management (DRM) to protect the files from unauthorized access. EPUB files are designed to be lightweight, compressed and to be reflowable; that is, the text can be adjusted to adjust to the size of a device’s screen. This makes them ideal for mobile devices such as tablets and phones. Furthermore, EPUB files can be read on many popular software e-readers and on most platforms such as Windows, macOS, iOS, Android and Linux. EPUB files contain rich, dynamic interactions and can include tables and diagrams, embedded media, footnotes, and more. They are also highly accessible, allowing people with vision impairments to access the text. Overall, the EPUB file format is a convenient, versatile and accessible way to read digital books and documents, making it an ideal choice for digital publishers.
