Introduction DjVu is a computer file format designed primarily to store scanned documents, especially those containing a combination of text, line drawings, indexed color images, and photographs. 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 DjVu uses technologies such as image layer separation of text and background/images, progressive loading, arithmetic coding, and lossy compression for bitonal (monochrome) images. This allows for high-quality, readable images to be stored in a minimum of space, so that they can be made available on the web. 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.
