The GPD (Graphic Photo Definer) image format was developed by RGB Light as an alternative to the .PNG and .GIF formats. It uses lossless image compression that can greatly reduce the size of graphic files.

GPD files can be viewed using PhotoDefiner or other third-party programs. They can also be opened with QuickTime Player and the QuickTime Web plugin if the PhotoDefiner component is installed.
