Convert LRF to LIT

The LRF (Sony Portable Reader File) is a proprietary eBook format developed by Sony for its eReaders, such as the Sony Reader. It stores eBooks and textual content in a compressed binary format, including text, images, and pagination data. Introduced as part of the Broad Band eBook (BBeB) family, LRF files are unencrypted, whereas their encrypted counterparts use the LRX extension. The format became obsolete in 2010 when Sony transitioned to the EPUB format. Despite its obsolescence, LRF files can still be opened and converted using various software tools.

The LIT file extension, short for Literature, is an eBook format developed by Microsoft for use with its Microsoft Reader application, first released in 2000. LIT files contain eBook content along with Digital Rights Management (DRM) protection. Microsoft discontinued Reader in 2012, making third-party software necessary to open LIT files. Despite its decline, LIT files are still encountered occasionally.
