Information about FB2 and AZW3 file formats
|Full name||FB2 - FictionBook||Amazon KF8 eBook File|
|File extension||.fb2, .fb2.zip||.azw3|
|Developed by||Dmitry Gribov||Amazon|
|Type of format||e-book file format|
|Description||FictionBook is an open XML-based e-book format which 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. It has a number of 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 utlises 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. The basic format remains as a PDB file similar in structure to a MOBI. More oftent than not a KF8 file will contain both a MOBI file at the beginning and the newer KF8 version of ePub later.|
