LRF to MOBI converter

LRF stands for the proprietary SonyPortable Reader File format, used for digital publications and documents. It is the native file format for the Sony Reader and other Sony ebook devices. Unlike other ebook formats like ePub, which allow readers to use different platforms and applications, LRF is locked entirely in the Sony platform.

Files in the LRF format are basically archives of JPEG images created with the Sony Librie software, referencing an xml document with a table of contents. It supports DRM encryption and can be converted to other formats like ePub or PDF using third-party software.

The MOBI file format is an eBook format developed by Mobipocket, which was acquired by Amazon in 2005. This format is used for eBooks that contain rich content like Adobe PDFs, multimedia, tables, images, and text. MOBI files can be found in two different versions: the MOBI and the PRC version. They are both based on the same reference last version of the Open eBook publication specification.

MOBI files use a custom compression algorithm which makes them easier to handle and smaller in size. The format adds support for DRM and allows encryption of eBook content which is mainly used to protect copyrighted books. MOBI files are mainly used on Amazon Kindle devices or apps, but they can also be read on other devices like smartphones or PC programs.
