About the output format

When EPUB is the right output

EPUB is the open ebook standard — reflows text, supports tables of contents and metadata, works on every e-reader except Kindle (which uses MOBI/AZW3 natively but converts EPUB on upload). Convert to EPUB when publishing to Apple Books, Kobo, Google Play Books, or shipping direct-to-reader PDFs / DOCX manuscripts.

About the CBR Format

CBR (Comic Book RAR) is a digital comic book archive format that packages sequential comic page images into a single RAR-compressed file. Each page is stored as a separate image file (typically JPEG or PNG), and comic reader applications display them in alphabetical or numerical filename order to recreate the reading experience. CBR has been one of the most popular formats for digital comic book distribution and personal comic archiving since the early 2000s.

While CBR offers good compression ratios thanks to RAR's algorithm, many modern comic reading apps and devices prefer CBZ (ZIP-based) due to its broader compatibility and open compression standard. Converting CBR to PDF makes comics readable on any device with a PDF viewer, while converting to CBZ improves compatibility with comic reader apps like CDisplayEx, ComicRack, and Chunky. The conversion preserves full image quality, page ordering, and resolution of the original comic pages.
