How to convert OBJ to GLTF
- Add your .OBJ file - drop it in the box above or click to browse.
- Convert it to .GLTF in a few seconds.
- Download your new .GLTF file.
What to expect
- OBJ uses an older Phong-based material model (
.mtl); the PBR conversion may make reflective or transparent surfaces look slightly different. - If the
.mtlfile or textures are missing during conversion, the output GLTF will have geometry only and the model will appear grey. - OBJ has no animation or scene hierarchy; any such data in the GLTF output comes only from edits made in a 3D editor after import.
Frequently asked questions
Does GLTF keep my textures?
Yes, provided the
.mtl file and texture images were present during conversion. In .glb format they are embedded in the file; in .gltf they remain as separate external files.What is the difference between `.gltf` and `.glb`?
GLTF is a JSON text file that references external binary and texture files; GLB packs everything into one binary bundle, which is simpler to share or upload.
Can I convert without installing software?
Yes - use the free converter on this page or 3DViewer.net, both of which require no installation.
What if I only have the `.obj` file and no `.mtl`?
The geometry converts fine, but without a
.mtl the GLTF will have no materials and the model will appear with a default grey material.
