Extract text from 3D Groove models (3GM)
To convert 3GM 3D models to another format, you need 3D Groove GX or other 3D software.
To convert other file formats to the "Legacy Web 3D Model" file type, you need software like 3D Groove GX or a similar tool.
The .3gm file extension represents a 3D Groove Model, a proprietary 3D asset format developed by The Groove Alliance. These files were primarily used in the late 1990s and early 2000s to store 3D geometry, textures, and animation data for web-based games and interactive experiences, often running alongside Adobe Shockwave.
Because the 3D Groove engine was discontinued decades ago, .3gm files suffer from severe accessibility disadvantages. They require long-obsolete authoring software or legacy browser plugins that are completely incompatible with modern operating systems. This creates a massive roadblock for game preservationists, researchers, or 3D artists attempting to recover old digital assets.
To modernize these files, users must convert them to standard, open 3D formats like OBJ, GLTF, or FBX. However, this is a closed, proprietary format with undocumented binary structures. Standard online converters fail to process it because they lack the specific legacy decoders required to parse the archaic vertex data.
Often, only specialized reverse-engineering tools or the original, out-of-print software can properly read or export the data. If our analysis detects a supported underlying structure or extractable mesh data, viewing or conversion may still be successful.
Convert.Guru analyzes your 3GM file, detects the exact format, and lets you read the text inside.
Users also converted MG files.
If you want to convert 3GM file to MG, you can use 3D Groove GX or similar software from the "Web 3D Model Storage" category. In the File menu, look for Save As… or Export….
To convert files to 3GM, try 3D Groove GX or another comparable tool in the "Web 3D Model Storage" category.
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 3GM converter.
