Q: What file formats can I convert to eBook?
A: You can convert a variety of file formats into eBooks! Supported formats include PDF, DOC, DOCX, EPUB, MOBI, and many more. Just upload your file, and we’ll handle the conversion for you.
Q: What’s the best ebook format for a professional ebook?

Q: What’s the difference between MOBI and EPUB?
A: MOBI is the format specifically for Kindle devices, while EPUB is the universal eBook format used by most other e-readers (like Kobo and Nook). The main difference is device compatibility.
Q: Is it possible to convert a large ebook (over 100MB)?
A: We do support large files, though conversion may take a bit longer depending on the file size. If your file exceeds the limit, we suggest breaking it down into smaller chunks first.

A: Currently, we don't offer direct conversion to Google Docs format. However, you can convert your ebook to a DOCX file, which can then be uploaded to Google Docs easily for further editing.
Q: How do I convert ebooks for Kindle?
A: Kindle supports the AZW and MOBI formats, so just convert your ebook to either of these using RunConvert. Once converted, you can upload it to your Kindle device via USB or email.
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.
RB is Developed by: NuvoMedia
RB was Released on: 1998
