Convert FB2 to RB

Understanding FB2 and RB file formats

FB2 (FictionBook 2.0) is an open XML-based eBook format popular in Russian-speaking communities. It is designed for storing fictional literature and supports rich metadata, structured content, and easy conversion to other formats.

RB (Rocket eBook) is an older eBook format used by the Rocket eBook reader. It is a binary format that packages text and images for use on early dedicated eBook devices. While less common today, RB files are still used for legacy device compatibility.
