Convert CBR to LRF

The CBR (Comic Book RAR Archive) file extension is used for storing and displaying digital comic books. It compresses a series of images, typically in JPEG, PNG, or GIF formats, into a single RAR archive, facilitating easy sequential viewing. Originating in the 1990s, the CBR format was popularized by David Ayton's CDisplay software, which optimized the reading experience by automatically ordering pages. This format has since become a standard for digital comics, supported by various comic book reader applications.

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.
