- Description
- 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.
- A KEPUB file is an EPUB ebook with extra Kobo markup (koboSpan elements and a kobo.js script) that Kobo e-readers use for their faster renderer, page statistics and highlighting. It is usually saved as .kepub.epub; any EPUB reader can open it.
