An AZW3 file is an eBook created in the Kindle Format 8 (KF8), Amazon's successor to the .AZW format. It supports newer features such as HTML5 and CSS3 support as well as many other formatting capabilities. AZW3 files often include DRM protection and are used as the download format for many Amazon eBooks.
An EPUB file is a digital ebook saved in the EPUB format, an open XML-based format for digital books and publications. It provides a standard digital publication format for publishers and consumers. EPUB files can be viewed with supporting software programs and hardware devices, such as the Sony Reader and Barnes & Noble Nook.
