What Is an EPUB File?

An ePUB file (Electronic Portable Book format or EPUB for short) is a digital book or ebook specifically formatted to be read on electronic devices like tablets, smartphones, and e-readers. An EPUB consists of HTML pages with images as well as any assets to create its content easily downloaded in ZIP archive file form.

ePUB was developed by the International Digital Publishing Forum (IDPF) and has become an open standard. These files can be designed as reflowable – meaning that their size adjusts automatically based on screen sizes and font sizes – making them suitable for long-form reading such as novels, textbooks, and other forms of continuous content such as textbooks.

EPUB files may be directly created or converted from other formats like PDF. Opening and reading an EPUB file, e-reading software such as Apple Books for iOS devices, Google Play Books (Android), or Adobe Digital Editions (Windows and macOS) should be utilized.
