About GMMP files

The .GMMP file extension refers to a Gamut Map Model Profile used by the Windows Color System (WCS). Unlike traditional binary ICC profiles, .GMMP files are structured as XML documents. Their primary function is to define the algorithms and parameters for mapping colors from a source device's gamut (like a monitor) to a destination device's gamut (like a printer). While the text-based nature of .GMMP makes them transparent, they are specialized system files often locked within the Microsoft Windows color infrastructure. Users often find themselves unable to "open" these files in standard image viewers because they contain mathematical mapping instructions, not pixel data. For debugging or auditing color workflows, converting these files to standard TXT or XML allows developers and color scientists to inspect the underlying schema without specialized WCS tools. For cross-platform compatibility, these proprietary definitions often need to be recreated as standard ICC profiles, as .GMMP is not natively supported on macOS or Linux.

Convert.Guru analyzes your GMMP file, detects the exact format, and lets you read the text inside.

Users also converted CAMP, CDMP and MP4 files.
