FB2 - FictionBook Ebook format


Format introduction:

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.

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 tag, so the size of the embedded images is increased by approximately 37%. FictionBook files are often distributed inside Zip archives.
