What is RB (RocketBook)?
RB (RocketBook) is a proprietary ebook format developed for the Rocket eBook reader, one of the first dedicated e-readers launched in the late 1990s. This format supported basic formatting, hyperlinks, and images while optimizing content display for the Rocket eBook's screen specifications.
RB files represent an important historical milestone in ebook development, bridging the gap between early personal digital assistants and modern e-readers. Though the format is now obsolete with the discontinuation of Rocket eBook devices, it established many conventions later adopted by mainstream ebook formats. Supported extension is .rb.
How to open RB?
Opening RB files today is challenging as the original Rocket eBook Reader software is no longer maintained and was designed for older operating systems. No modern e-readers or applications provide native support for this legacy format.
The most effective approach to accessing RB content is through conversion. Specialized software like Calibre with appropriate plugins can convert RB files to contemporary formats like EPUB or MOBI, though some formatting features may not transfer perfectly due to the format's age and proprietary nature.

What is EPUB (Electronic Publication)?
EPUB (Electronic Publication) is a widely used open standard for digital e-books and publications. EPUB files are designed to be reflowable, meaning the content adapts to different screen sizes and orientations, making it suitable for a variety of devices including e-readers, smartphones, and tablets.
EPUB supports text, images, and multimedia, and is commonly used for distributing e-books in formats that are easy to read on a wide range of devices. It’s supported by most e-book readers except Amazon Kindle, which uses its own proprietary formats.
How to open EPUB?
EPUB files can be opened with a variety of e-reader applications, such as Adobe Digital Editions, Calibre, and Apple Books.
On Windows, Calibre is a popular tool for reading and managing EPUB files, while macOS users can use Apple Books or other third-party apps like Calibre or BookReader.
