The RB file extension stands for Rocket eBook File, used by the Rocket eBook device from NuvoMedia, introduced in 1998. It is a container format for eBooks, typically holding HTML content and metadata. Although it supports DRM, modern eBooks no longer use this feature. The format includes a unique file structure with specific byte sequences for versioning and content organization.
The AZW3 file extension, also known as Kindle Format 8 (KF8), is a proprietary eBook format developed by Amazon. Introduced in 2011 alongside the Kindle Fire, AZW3 supports advanced formatting features such as HTML5 and CSS3, enhancing the visual presentation of eBooks. It is primarily used for Amazon Kindle devices and applications, providing a richer reading experience compared to its predecessor, AZW. The format is backward-compatible with MOBI, ensuring older Kindle devices can still access the content.
