CBT (Comic Book TAR) is a comic archive format that stores images in a TAR (Tape Archive) container. It is the least common of the CB* family but appears in older comic collections where TAR archiving was used instead of RAR or ZIP. CBT provides the same page-by-page reading experience as CBR and CBZ without any additional features. Converting CBT to modern ebook formats allows the content to be catalogued, displayed, and read on e-readers that do not support raw TAR archives.
Converting CBT to FB2 extracts the sequentially ordered images from the CBT archive and repackages them within a FB2 container. 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.
Comic archives convert to FB2 as image sequences. Ensure the archive contains images in correct alphabetical/numerical order, as Calibre relies on filename ordering. High-resolution images produce larger output files; consider resizing images beforehand. 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 CBT to FB2 entirely in the cloud — no software installation needed. Files are deleted from our servers within 24 hours of upload.
