EPUB to LRF converter

The EPUB file format is an open standard for e-books and other digital publications. It is widely used for distributing digital books, magazines, newspapers, and other electronic publications. Developed by the International Digital Publishing Forum (IDPF) and supported by various e-book readers, EPUB is the most commonly used digital book format in the world.

The EPUB format is based on OpenXML and HTML and can be read on both desktop computers and mobile devices. It is capable of incorporating media files, images, XHTML, CSS, cover images, text documents, indexing and navigation features. The format is also designed to ensure that users can easily re-size text to their viewing preferences without compromising the original layout.

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.
