How to convert GLB to OBJ
- Add your .GLB file - drop it in the box above or click to browse.
- Convert it to .OBJ in a few seconds.
- Download your new .OBJ file.
What to expect
- Animation is not supported by
.obj- any skeletal rigs or keyframes in the GLB are lost; export to FBX instead if you need animation. - PBR materials are downgraded to the basic
.mtlformat (Phong shading), so metallic, roughness, and occlusion maps may look different after conversion. - An OBJ export is always multiple files: a
.obj, a.mtl, and separate texture images - keep them in the same folder or textures will not load.
Frequently asked questions
Does OBJ support multiple meshes from a single GLB scene?
Yes - each mesh is written as a named group in the
.obj file, which most 3D apps can address separately.Will textures transfer when I convert GLB to OBJ?
Texture images export as separate files alongside the
.obj, referenced by the .mtl. PBR effects like roughness and metallic are approximated, not transferred exactly.Why does my converted model appear rotated 90 degrees?
GLB uses a Y-up coordinate system; if the target app defaults to Z-up, the model may appear tilted. Apply a -90 degree X-axis rotation during Blender export or correct it in the receiving app.
Can I batch-convert multiple GLB files to OBJ?
Yes - the Assimp CLI and Python
trimesh library both support scripted batch conversion, making them practical choices when processing many files.
