MDL is a generic extension used for 3D model files in different programs like MATLAB, Simulink, or Valve’s Source Engine. Its structure and contents vary depending on the software, but it generally contains 3D geometry, animations, or simulation data.
OBJ is a 3D model format that stores geometry data like vertices, edges, faces, and texture coordinates. Developed by Wavefront Technologies, it's widely supported across 3D modeling and game engines. OBJ files can also be paired with .MTL files for materials.
Convert your .mdl files to .obj right in your browser — no downloads, no installs. Everything happens securely in the cloud.
We never store your files permanently. Only you can access them, and they’re automatically deleted from our servers within 2 hours.
Turn your MDL files into OBJ in just a couple of clicks. No registration, no limits — and it’s 100% free.
