The epub file extension is exclusively related to the Open Publication structure eBook file format.
Open eBook is an e-book file format based on XML language and defined by the Open Publication Structure specification. It is purely designed for reflowable digital books and publications.
Generally, the EPUB file format combines three open standards: the IDPF-defined Open Publication Structure (OPS), Open Packaging Format (OPF), and Open Container Format (OCF).
EPUB offers publishers the means to create and send a single digital publication file through distribution. At the same time, it offers end users and consumers interoperability between software and hardware for unencrypted reflowable digital publications.
Epub is a common file format for digital books today. There are plenty of e-book services and stores, software readers, and epub converters for all platforms and devices.
To open and read epub formatted files, you need an ebook-reader app like those available on tablets or e-readers like the Kindle or Nook.
The *.epub files are widely supported by many ebook readers software that are available across many platforms for both computers or hand-held devices.
As EPUB is somewhat of a standard for ebooks today, there is plenty of ebook converters that can help you with conversion to other document file formats. See suggested conversions or software below.
