How do I convert an MTL file to GLTF?

Upload your MTL file along with its corresponding OBJ and texture maps. Select GLTF as the output format and click Convert. Our tool automatically translates MTL's ambient, diffuse, specular, and transparency values into GLTF PBR materials. Download the resulting .gltf file (or .glb) with all textures embedded.

Why should I convert MTL to GLTF instead of keeping OBJ/MTL?

GLTF is a modern runtime-friendly format built for web, AR/VR, and game engines. Combining geometry and materials into a single GLTF file reduces file count and load times. It also standardizes on PBR materials, so your 3D models look consistent and physically accurate across all supporting applications.

Will my textures and transparency survive the MTL to GLTF conversion?

Yes, our converter preserves all relevant texture maps and maps MTL's d/Tr transparency to GLTF's alpha mode. Color spaces and UVs are retained. Some legacy MTL attributes like sharpness, optical density, or illumination models are not representable in GLTF and are safely ignored during conversion.
