What are EPUB files and how to open them

Are you having problems opening an EPUB file or are you simply curious about its contents? We're here to explain the properties of these files and provide you with software that can open or handle your EPUB files.

What is an EPUB file?

An .EPUB file is an Open Publication Structure eBook file.

The .epub file extension is often given to files that have been created by applications that use the Open eBook XML file format. These files are composed of three open standards including the Open Packing Format, the Open Publication Structure, and the Open Container Format.

The EPUB file format allows eBook publishers to produce unencrypted reflowable digital eBooks. The EPUB files consist of a ZIP file that contains the contents of the eBook and an XML file that describes the contents of the ZIP file itself.

In order to read an eBook that has been published in the EPUB file format, you must have a compatible eBook reader.
