Convert OBJ to GLB online
Convert OBJ to GLB to turn a multi-file model into a single self-contained one. An OBJ references a .mtl material file which references texture images; GLB packs all of it into one binary, which is why it is the practical choice for the web and AR.
When should you convert OBJ to GLB?
- Publish a textured model on a web page
- Send a complete model as one file instead of a folder
- Prepare a model for an AR viewer or a 3D product configurator
- Stop textures from going missing when a model is shared
Before you convert
Upload the sidecars too
A textured OBJ is genuinely several files. Include the .mtl and the texture images with the model, or the GLB will come out untextured.
Blender does the textured export
Where materials and textures need to survive, the job is handed to Blender rather than a geometry library — which is what makes the material graph carry across faithfully.
What happens to your file
The OBJ mesh is loaded and re-exported as GLB. Straight geometry conversions go through trimesh; when textures and materials need to survive the trip, the job is handed to Blender instead.
Settings this conversion runs with
| Loader | trimesh |
|---|---|
| Textured path | Blender (GLB, glTF, OBJ) |
| Materials | Preserved |
What changes
- GLB packs the mesh, materials, and textures into a single binary file, which is what makes it the practical choice for the web and AR viewers.
