DescriptionLRF (short for "Broadband eBook format") is a proprietary eBook format developed by Sony that is specifically designed for their line of eBook readers, such as the Sony Reader. LRF files use the Sony BBeB ("BroadBand eBook") eBook format, which is based on XHTML and can include images and other multimedia content.
Technical detailsLRF files are designed to be highly optimized for viewing on e-book readers, with support for embedded fonts, images, and other advanced features. The format also supports reflowable text, meaning that the text can adjust to fit the size of the screen without losing its formatting. In order to create LRF files, authors must use the Sony eBook Library software, which allows them to import text, images, and other elements and create a fully formatted e-book. LRF files can also be created by converting other e-book formats using third-party conversion software.
