RB to JIF conversion is the process of transforming an ebook or document stored in the RB (a reflowable or fixed-layout eBook package used by certain reading apps and legacy e-reader systems) format into a JIF file, a JPEG Interchange Format variant used for single-image cover art or page images. This conversion extracts the visual or page content from the RB container and encodes it as JIF images so pages, covers, or illustrations can be viewed in standard image viewers or embedded in other digital products.

Keep individual output JIF images under 2–3 MB for fast loading on web and mobile; reduce resolution for long documents to maintain manageable total size.
