About RB files
The .rb file extension primarily identifies a source code file written in the Ruby programming language. These files contain plain text scripts executed by the Ruby interpreter or utilized in web frameworks like Ruby on Rails. A notable secondary use for .rb files is in Pokémon Essentials, a set of scripts used within RPG Maker XP for custom game creation. Additionally, older .rb files might be Rocket eBook files, an obsolete digital book format developed by NuvoMedia.
For programming purposes, .rb files are simple text, but they lack built-in formatting for non-developers and require a code editor like Visual Studio Code to read comfortably. If you need to share code snippets with non-technical stakeholders or archive them, leaving them in .rb is a disadvantage because standard office software will not format the code correctly and might inadvertently execute the script if misconfigured. Older Rocket eBook .rb files are essentially useless on modern devices because the proprietary NUVO format is heavily restricted and unsupported by current e-readers.
To make these files usable across different environments, you must convert them. For web sharing or documentation, convert Ruby code to PDF or standard TXT. For obsolete Rocket eBook files, convert them to standard EPUB or PDF to read them on modern devices like the Kindle or Apple Books. Drag and drop your file here to analyze and convert it - free, online, and without installing software.

The RB Converter Story
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our RB converter.
