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. EPUB is an e-book 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.
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. 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, a 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.
