Convert IM files online for free
The converter easily converts your IM file to various formats - free and online. No Trainz Simulator or or other 3D software needed.
To convert other file formats to the "Game Asset Mesh" file type, you need software like Trainz Simulator or a similar tool.
The .IM file extension primarily represents the Indexed Mesh format, a proprietary binary 3D model structure used extensively by the Trainz Simulator franchise (developed by N3V Games). These files contain the compiled geometry, skeletal animations, and texture mapping data required to render locomotives, rolling stock, and scenery within the game engine.
The Problem: Because .IM files are "cooked" (compiled) for runtime performance, they are not natively supported by standard 3D modeling software like Blender or Autodesk 3ds Max. This proprietary lock-in is a common source of difficulty for modders who wish to repair assets, update legacy content, or port models to other engines, as the files cannot be opened directly.
The Solution:
Use Convert.Guru to open and convert your IM file.
Users also converted IM0, IM1, IM_0001, IM_, IM2, IM000001, IM_0002, IM_0003, IM000002, IM_00001, IM3, IM000000 and IM00001 files.
If you want to convert IM file to WEBP, CUR or PSB, you can use Trainz Simulator or similar software from the "Trainz 3D Mesh Model" category. In the File menu, look for Save As… or Export….
To convert RAW, PNG, AI, NEF, PSB, DNG, SVG, GIF, EPS, JPG, ARW or PDF files to IM, try Trainz Simulator or another comparable tool in the "Trainz 3D Mesh Model" 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 IM converter.
