Format Information
HTMLZ
HTMLZ (HTML ZIP) is a compressed ebook format that packages HTML content, stylesheets, and images into a single ZIP archive. It serves as a useful intermediate format for ebook conversion workflows, preserving the full HTML structure and styling of the content. HTMLZ is supported by Calibre and is particularly useful for custom ebook processing pipelines and format migration.
LRF
LRF (Sony Portable Reader File) is an ebook format developed by Sony for its line of e-reader devices. Also known as BBeB (BroadBand eBook), LRF supports text reflow, embedded fonts, images, and basic formatting. While Sony has moved to EPUB for newer devices, LRF remains important for users with older Sony Reader models and legacy ebook libraries.
