RB (Rocket Book) is the format used by the Rocket eBook, one of the first commercial e-readers, manufactured by NuvoMedia and released in 1998. The Rocket eBook preceded Amazon Kindle by nearly a decade and established many conventions for portable digital reading. RB files have very limited styling and are tied to the Rocket eBook hardware. Converting RB files to modern formats is a preservation effort to make early digital book history accessible on current devices.
Converting RB to TXT involves parsing the proprietary RB binary structure and reconstructing the text and metadata as a TXT file. 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 resulting TXT file contains clean UTF-8 text suitable for indexing, analysis, or reprinting.
Plain Text (TXT) is the most universally readable output format, viewable on any device without special software. Converting to TXT extracts the textual content of an ebook, stripping all formatting, images, and metadata. This is useful for full-text search indexing, natural language processing, accessibility tools, and feeding content into other pipelines. TXT output from Calibre uses UTF-8 encoding and preserves paragraph breaks.
TXT output strips all formatting and images. If the original RB contains footnotes or endnotes, they will appear inline. Use find-and-replace in a text editor to clean up any leftover markup artifacts. Our conversion engine processes RB to TXT entirely in the cloud — no software installation needed. Files are deleted from our servers within 24 hours of upload.
