|EPUB is an ebook file format with the extension .epub that can be downloaded and read on devices like smartphones, tablets, computers, or e-readers. It is a free and open standard published by the International Digital Publishing Forum (IDPF). The term is short for electronic publication and is sometimes styled ePub.
|AZW3 - Kindle Format 8 (KF8) is Amazon's newer version of AZW. It supports HTML5 and CSS3, which were not supported through the standard AZW format. In addition, it has several other formatting options and is used by Amazon for all new Amazon eBooks. It is supported by fourth-generation Kindle devices running firmware version 4.1.0 or later and the Kindle Fire device.
|🔸 Technical details
|EPUB is the most widely supported vendor-independent XML-based (as opposed to PDF) e-book format. An EPUB file is a ZIP archive that contains, in effect, website-including HTML files, images, CSS style sheets, and other assets. It also contains metadata. EPUB 3 is the latest version. By using HTML5, publications can contain video, audio, and interactivity, just like websites in web browsers.
|KF8 (also called AZW3) is essentially a compiled ePub that has utilizes a Palm database and Amazon's DRM scheme. It targets ePub 3 version support, but existing ePub can also be used. The internal format has been decoded using mobi_unpack. However, the basic format remains as a PDB file similar in structure to a MOBI. Thus, more often than not, a KF8 file will contain both a MOBI file at the beginning and the newer KF8 version of ePub later.
