Information about FB2 and AZW3 file formats

Name FB2 AZW3
Full name FB2 - FictionBook Amazon KF8 eBook File
File extension .fb2, .fb2.zip .azw3
MIME type application/octet-stream
Developed by Dmitry Gribov Amazon
Type of format e-book file format
Description FictionBook is an open XML-based ebook format that originated and gained popularity in Russia. FictionBook files have the .fb2 filename extension. The FictionBook format does not specify the appearance of a document; instead, it describes its structure. For example, there are special tags for epigraphs, verses, and quotations. 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 In contrast to other eBook formats (e.g., ePub), a FictionBook document consists of a single XML file. Images are converted to Base64 and reside inside the <binary> tag, so the size of the embedded images is increased by approximately 37%. FictionBook files are often distributed inside Zip archives. 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.
