EPUB files normally include an index page for navigation, and accessibility features to adjust text size or allow for text-to-speech. The EPUB format comprises three open standards – one defining content markup, one describing the ebook structure, and one packaging all the files into a compressed format.

The EPUB standard is now maintained by a World Wide Web Consortium (W3C) working group. Amazon announced in 2022 that new Kindle models would also support EPUB files. EPUB files can be viewed on a wide range of e-readers and digital reading apps, including NOOK, Apple Books, Okular and Calibre. The format was developed in the mid-late 2000s by the International Digital Publishing Forum and is an alternative to formats like AZW, developed for the Kindle. EPUB is short for ‘electronic publication’. AZW and AZW3 ebooks are available to purchase from the Amazon Kindle Store.ĮPUB is the standard open-source format for ebooks. Because it’s Amazon’s proprietary format, AZW files will not open with most other ereaders, but you may be able to open them with Calibre’s ebook software. However, AZW files should still be readable on most newer Kindles, and you can also download the Kindle app for smartphones, tablets, PCs and Macs. In 2011, Amazon introduced the newer AZW3 format which has more functionality than AZW. DRM is intended to stop users from copying and sharing whole books or sections with other users. Like the earlier MOBI files, AZW files are normally protected by digital rights management (DRM) technology. The files can contain interactive contents pages and book navigation, as well as the main content of the book and basic graphics. AZW is sometimes known as the Kindle File Format. The AZW ebook format was created by Amazon to use with its Kindle ereaders.
