What is FB2?
FB2 is an open XML-based e-book format that keeps text, metadata and illustrations in a single file with Base64-embedded images; it is most popular in Russian-speaking regions.
About the format
FB2 (FictionBook 2) is an open XML-based e-book format that is very popular in Russian-speaking regions. Body text, metadata and illustrations all live in one XML file, with images usually embedded as Base64, so a single .fb2 is a complete book that is easy to distribute. It has clean structure and carries chapters and author data natively; the drawbacks are larger size (Base64 inflates images by roughly a third) and less reader support outside Russian-language markets.
