Q: How do I ensure my eBook looks good on mobile devices?
A: Good question! When converting, make sure you choose a flexible eBook format like EPUB, which adjusts its layout based on screen size. This ensures your content looks great whether viewed on a small phone or a larger tablet.
Q: How do I preserve my book’s images during conversion?
A: We try to preserve images as much as possible during conversion, especially for formats like ePub and PDF. However, some image quality may be lost depending on the output format.

A: Definitely! Most eBook formats, like EPUB and MOBI, support chapter breaks. You just need to make sure your original document is properly formatted with headings or page breaks.
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 was Released on: 1998

What is LRF (Portable Reader File)?
LRF (Portable Reader File) is a proprietary ebook format developed by Sony for its Sony Reader devices. Based on the Broad Band eBook (BBeB) format, LRF files store formatted text, images, and metadata in a compact binary structure optimized for Sony's e-ink displays.
LRF files offer features like fixed page layouts, embedded fonts, and high-quality image display. Though Sony has since transitioned to more standard formats like EPUB, a significant library of legacy content exists in LRF format, particularly Japanese literature and manga published for early Sony Reader models. Supported extension is .lrf.
How to open LRF?
LRF files can be opened natively on Sony Reader devices, including the PRS-500, PRS-505, and PRS-700 models. For other platforms, dedicated software is limited since Sony discontinued support for this proprietary format.
Currently, the most effective way to access LRF content is through conversion. Ebook management software like Calibre can convert LRF files to more widely supported formats like EPUB or PDF. Some specialized applications like LibreOffice with appropriate extensions may also be able to read certain LRF files.
