Extract text from M3G files
To convert your M3G file to another format, you need Blender or other 3D software.
To convert other file formats to the "J2ME Game Asset" file type, you need software like Blender or a similar tool.
The .M3G file format is a binary 3D scene graph standard defined by JSR 184 (Mobile 3D Graphics API) for use in Java ME (J2ME) applications. It was the dominant format for 3D games on feature phones (like Nokia and Sony Ericsson) in the mid-2000s, containing meshes, textures, camera data, and animations in a highly compressed structure optimized for low-bandwidth devices.
Because .M3G is a legacy mobile format, it is not supported by modern 3D software like Autodesk Maya or Blender natively. Users typically need to convert these files to extract 3D assets from old mobile games for preservation or modding. Direct conversion is difficult due to the format's binary nature and lack of documentation; successful extraction often requires specialized "software archaeology" tools or legacy versions of Blender (e.g., 2.49b) with specific import scripts. For modern workflows, the best target formats are OBJ (for static geometry), GLTF (for web and engines), or FBX (for preserving hierarchy).
Convert.Guru analyzes your M3G file, detects the exact format, and lets you read the text inside.
Users also converted OBJ, JPG, PVR, BIN, WF1, LCP and PHC files.
If you want to convert M3G file to OBJ, FBX, DAE, 3DS, MAX, BLEND, MA, MB, C4D, STL, PLY or WRL, you can use Blender or similar software from the "Mobile 3D Scene Graph" category. In the File menu, look for Save As… or Export….
To convert DWG, DAE, X3D, IGES, WRL, JT, SKP, 3DS, 3DM, OBJ, STEP or FBX files to M3G, try Blender or another comparable tool in the "Mobile 3D Scene Graph" 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 M3G converter.
