Convert GLB to OBJ
Export the geometry of a GLB scene as a Wavefront OBJ. This is useful for pipelines that accept OBJ but not glTF; materials and textures are not transferred.

What changes in the conversion
Dropped
- PBR materials and textures
- Animations and scene graph
- No MTL file is generated
Common mistakes
- A GLB with only lights or cameras produces an empty OBJ and is rejected.
- Materials will be missing in the target software unless you rebuild them.
- Very large scenes can exceed the 100 MB limit.
For 3D printing
- OBJ is rarely the best printing format; use STL or 3MF when possible.
- If you import the OBJ into CAD, check the unit scale first.

Frequently asked questions
Where is the MTL file?+
There is none. This converter writes geometry only, which keeps the result small and dependency-free.
Will the textures survive?+
No. OBJ needs a separate MTL and image files; this tool does not export them.
Can I convert a GLTF file?+
This page handles GLB. For a .gltf file with external buffers, pack it as GLB first.
Need a model instead of a conversion?
Turn a photo, a drawing or a logo into a 3D model, then export it in the format you need.
