About RGB files

An .RGB file is a legacy raster image format created by Silicon Graphics, Inc. (SGI) for their high-end graphics workstations. Today, it is primarily encountered as raw, rendered output frames from 3D modeling applications like Autodesk 3ds Max or Pixar RenderMan. Less commonly, the extension is used for scientific color map palettes in tools like Generic Mapping Tools (GMT).

The primary disadvantage of the .RGB format is its severe lack of modern compatibility. Because it was designed for 1990s hardware, files are either completely uncompressed or use basic Run-Length Encoding (RLE). This results in massive file sizes. Furthermore, standard operating systems (macOS Preview, Windows Photos) and all modern web browsers completely ignore SGI formats. You cannot embed them in websites, email them to clients, or easily preview them without installing specialized legacy image viewers like IrfanView or XnView.

To make these files usable, conversion is mandatory. For web use and general sharing, convert .RGB to JPG or WebP. If you need to preserve the exact lossless pixel data of a 3D render for compositing, convert to PNG or TIFF. Drag and drop your file to analyze and convert it - free, online, and without installing software.

The RGB 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 RGB converter.
