Frequently Asked Questions
Here are some common questions and answers about rb file conversions ask by our users on RunConvert.com.
Frequently Asked Questions
Q: Are there file size limits for ebook conversion?
A: Yes, for best performance, we recommend keeping your files under 100MB. Larger files might take a little longer to convert, but we’re still happy to process them!
Q: Can I convert a scanned document to an eBook?
A: Unfortunately, no. Scanned documents are typically images, and converting them into eBooks requires text-based content. However, you can use OCR (Optical Character Recognition) tools to extract text first before converting.
Q: What is the best eBook format for academic papers?
A: EPUB is a great choice for academic papers because it allows text to reflow, making it readable on a variety of devices. However, if you need strict layout preservation, PDF is still the go-to format.
Q: Will my ebook’s metadata (title, author, etc.) be preserved?
A: Yes, metadata like the title, author, and publication date will be retained during the conversion process, ensuring your ebook remains properly categorized.
Q: Do you support eBook creation from scratch?
A: We currently focus on file conversion, but if you have a manuscript ready and need help with eBook formatting, there are plenty of online tools to assist in the creation process before converting.
Q: Can I convert a scanned PDF ebook to ePub?
A: Scanned PDFs are made up of images, not text, which makes conversion to ePub tricky. You might need to use OCR (Optical Character Recognition) software first to extract the text before converting to ePub.
Q: Why does my converted eBook look different from the original?
A: Ebooks adapt to different screen sizes and devices, which can sometimes cause formatting shifts. We try our best to preserve your formatting, but some minor tweaks might occur. It’s just how digital files work!
Q: How long does it take to convert an ebook?
A: Conversion time varies depending on file size and complexity, but it usually takes just a few seconds to a few minutes. You'll be notified once your ebook is ready for download!
Q: Can I convert an audiobook to an eBook?
A: Audiobooks and eBooks are pretty different, so direct conversion isn’t possible. However, if you have a transcript of your audiobook, you can easily convert that into an eBook format!
Q: Can I customize my eBook’s layout and design?
A: Yes, to an extent. eBook formats like EPUB allow some customization, but they’re not as flexible as a traditional print layout. If you’re after more complex designs, consider using specialized eBook publishing tools.
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

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.
EPUB is Developed by: International Digital Publishing Forum (IDPF)
EPUB was Released on: 2007
