What is an RGB file?

An RGB file is a color bitmap image, saved in a file format created by Silicon Graphics (SGI). It contains binary data used to show an image using the RGB color model. RGB files are similar to .SGI files.

Paul Haeberli invented the RGB format in 1995. It was used primarily to save raster images for display on Silicon Graphics workstations.

Both RGB and SGI files contain images comprised of three color channels (red, green, and blue). The similar .RGBA format contains images comprised of three color channels and an alpha channel, which stores transparency information.

How to open an RGB file

You can open an RGB file in many image viewers and editors, including File Viewer Plus (Windows), Apple Preview (Mac), XnViewMP (Windows, Mac), and qView (multiplatform).

How to convert an RGB file

Most image viewers and editors that can open RGB files can convert them to other image formats. For example, XnViewMP can convert RGB files to the following formats (and many others):

  • .JPEG - JPEG Image
  • .GIF - Graphical Interchange Format
  • .PNG - Portable Network Graphic
  • .TIFF - Tagged Image
  • .BMP - Bitmap Image

An RGB file may also be an image saved in the Q0 raster graphic format. Each RGB file is typically paired with an accompanying .FAL file. The FAL file contains header information that image viewers use to open the RGB file.

More Information

Some Japanese software programs create and use images saved in the Q0 format. Q0 images are 24-bit Red Green Blue (RGB) bitmap images, whose filenames use the .q0 or .rgb extension.
