Convert GLB to OBJ online
Convert GLB to OBJ when a modelling package will not import glTF. OBJ is one of the oldest and most widely supported mesh formats — nearly every 3D application reads it, which is exactly why it is still the fallback of choice.
When should you convert GLB to OBJ?
- Import a web or AR model into older modelling software
- Open a downloaded GLB in a tool that predates glTF
- Get materials as an editable .mtl file you can adjust
- Move a model into a pipeline standardised on OBJ
Before you convert
The result is several files
A textured OBJ needs its .mtl and texture images alongside it. The export is packaged as a ZIP so nothing arrives on its own and broken.
Scene structure is flattened
GLB can describe a hierarchy with nodes and transforms. OBJ describes meshes, so a structured scene comes out as geometry.
What happens to your file
The GLB mesh is loaded and re-exported as OBJ. 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
- OBJ normally stores its materials and textures in separate sidecar files. When the model is textured, the export is packaged as a ZIP so those files stay with the mesh instead of arriving alone and broken.
