GlTF to OBJ converter
Drop a glTF file and get an OBJ back in seconds. glTF is human-readable JSON, used mostly for debugging and hand-editing scene data. OBJ is plain text, read almost everywhere, the usual choice for older 3D software and CAD-adjacent tools. The conversion runs entirely in your browser, so your file never leaves your device.

How to use the gltf to obj converter
- 1Choose your glTF fileDrag it onto the panel or click to browse. It's read locally and never uploaded.
- 2Check the previewOrbit the model and check the triangle count, size and materials before converting.
- 3Download the OBJExport a OBJ with one click. Downloads are included with every plan.
What carries over
- glTF textures don't carry over: OBJ supports basic materials in a separate .mtl file.
- Animation and rigs are dropped; OBJ stores static geometry only. The model is exported in its rest pose.
- Units: glTF is metres by convention and OBJ is unitless. Numbers are copied 1:1, so check the size in the target app.
glTF vs OBJ
| glTF | OBJ | |
|---|---|---|
| Full name | GL Transmission Format (JSON) | Wavefront OBJ |
| Appearance | PBR materials; textures embedded as data URIs in our export | basic materials in a separate .mtl file |
| Animation | Yes | No |
| Units | metres by convention | unitless |
| Best for | debugging and hand-editing scene data | older 3D software and CAD-adjacent tools |
Questions
- Is my glTF file uploaded?
- No. The glTF is parsed and the OBJ is written by JavaScript in your browser tab. The file never reaches our servers.
- Will the OBJ look the same as the glTF?
- The geometry is identical. OBJ holds basic materials in a separate .mtl file, so surface appearance changes. See the notes above for this exact pair.
- Is there a file size limit?
- Files up to 150 MB open, but very large models depend on your device's memory. Desktop browsers handle big files best.
