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 RB wraps the plain or lightly styled RTF content in a fully structured RB 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 RB file retains the original book's content and structure for use on compatible devices.
RB (Rocket Book) is the format for the RocketBook e-reader, a pioneering device from 1998. Converting to RB is a specialized preservation task for collectors and digital historians who maintain original Rocket eBook hardware. The format has very basic styling capabilities and limited character encoding, so only simple text-based content converts cleanly. Most practical conversion workflows would target EPUB, MOBI, or PDF instead.
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 RB output has a proper title and author attribution. RB is a legacy format primarily for specific historical hardware. Verify your target device supports RB before converting. For modern devices, EPUB or MOBI are better choices. Our conversion engine processes RTF to RB entirely in the cloud — no software installation needed. Files are deleted from our servers within 24 hours of upload.
