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 MOBI extracts the sequentially ordered images from the CBT archive and repackages them within a MOBI 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 resulting MOBI file can be sideloaded directly onto Kindle devices via USB or email delivery.
MOBI is Amazon's legacy Kindle format, compatible with all Kindle devices and the Kindle app on iOS and Android. While Amazon's newer KFX and AZW3 formats have largely replaced MOBI for new publications, MOBI files can still be sideloaded onto Kindle devices via USB or sent via Kindle's email delivery. MOBI supports basic styling, tables of contents, and embedded images. It remains a practical choice for delivering ebook content to Kindle users who prefer offline sideloading.
Comic archives convert to MOBI 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. MOBI files can be sideloaded to Kindle by connecting via USB or by emailing to your Kindle's @kindle.com address. Kindle Personal Document Service supports MOBI uploads from any email address on your approved sender list. Our conversion engine processes CBT to MOBI entirely in the cloud — no software installation needed. Files are deleted from our servers within 24 hours of upload.
