DjVu (pronounced 'déjà vu') is a compressed image format optimized for scanned documents and digital books. Developed at AT&T Labs in the late 1990s, DjVu achieves compression ratios 3-8x smaller than PDF for scanned pages by separately compressing foreground text, background, and images. It is widely used in academic repositories, libraries, and archives for distributing scanned books and scientific papers. Converting DjVu to EPUB or PDF makes the content accessible on standard e-readers and mobile apps.
Converting DJVU to FB2 processes the DJVU source through Calibre's content pipeline to produce a well-formed FB2 output. Our conversion service uses Calibre, the gold-standard open-source ebook management tool, ensuring that text encoding, chapter markers, and embedded assets are faithfully transferred. The converted FB2 file retains the original book's content and structure for use on compatible devices.
FictionBook 2 (FB2) is the dominant ebook format in Russian-language markets and is the native format for FBReader, one of the most popular open-source e-readers. Its strict XML structure ensures perfectly consistent rendering and makes programmatic manipulation straightforward. FB2 files are very compact, well-suited for mobile devices with limited storage. Converting to FB2 is the right choice for distributing content on Russian-language ebook platforms and for use with FBReader.
DjVu files with multi-layer encoding (foreground/background separation) convert best when the DjVu has been created from original digital sources rather than scans. Scanned DjVu may need OCR to produce selectable text in the FB2 output. FB2 output works best with Calibre's strict XML validation enabled. Russian and Cyrillic text is particularly well-handled by FB2. FBReader on Android is the recommended reader for the converted FB2 file. Our conversion engine processes DJVU to FB2 entirely in the cloud — no software installation needed. Files are deleted from our servers within 24 hours of upload.
