RTF (Rich Text Format), developed by Microsoft in 1987, is a document interchange format designed to transfer styled text between word processors across different operating systems. RTF supports basic formatting: bold, italic, fonts, paragraph styles, and embedded images. It remains a widely understood format among word processors including LibreOffice, Word, and TextEdit. In ebook conversion, RTF serves as a bridge format between word processors and ebook readers, particularly for manuscripts being prepared for publication.
Converting RTF to LRF wraps the plain or lightly styled RTF content in a fully structured LRF container with metadata and navigation. Our conversion service uses Calibre, the gold-standard open-source ebook management tool, ensuring that text encoding, chapter markers, and embedded assets are faithfully transferred. The converted LRF file retains the original book's content and structure for use on compatible devices.
LRF is Sony Reader's native format, designed for the PRS series e-readers produced from 2006 to 2013. While Sony has since moved to EPUB and discontinued the PRS line, converting to LRF is still relevant for users with original Sony Reader hardware. LRF supports Sony's custom typography and margin settings, rendering text cleanly on Sony's E Ink displays. It is a niche but occasionally necessary output format for Sony Reader compatibility.
Plain and lightly formatted sources like RTF benefit from adding metadata (title, author, language) before conversion. Use the metadata fields in our converter to ensure the LRF output has a proper title and author attribution. LRF is a legacy format primarily for specific historical hardware. Verify your target device supports LRF before converting. For modern devices, EPUB or MOBI are better choices. Our conversion engine processes RTF to LRF entirely in the cloud — no software installation needed. Files are deleted from our servers within 24 hours of upload.
