glTF vs OBJ: what's the difference?
| Feature | glTF | OBJ |
|---|---|---|
| Geometry (mesh) | ✓ | ✓ |
| Color | ✓ | ✓ |
| Materials | ✓ | ✓ |
| UV textures | ✓ | ✓ |
| Best for | Web, AR & real-time | Modeling, rendering, games |
| File size | Medium (JSON + assets) | Larger (readable text) |
What is a glTF file?
glTF is the modern, web-native standard for 3D — often called “the JPEG of 3D”. The .gltf variant is JSON-based and carries full PBR materials, textures, UVs, scene hierarchy and even animation, making it ideal for the web, AR and real-time engines.
What is a OBJ file?
OBJ is one of the most widely supported 3D formats in existence. Beyond geometry it can reference materials through a companion .mtl file and store UV coordinates for textures, which makes it a go-to format for modeling, rendering and game engines.
Why convert glTF to OBJ?
GL Transmission Format (.gltf) is glTF is the modern, web-native standard for 3D — often called “the JPEG of 3D”. The .gltf variant is JSON-based and carries full PBR materials, textures, UVs, scene hierarchy and even animation, making it ideal for the web, AR and real-time engines.
Both formats carry similar data, so the conversion is lossless while making your model usable wherever OBJ is preferred. OBJ is one of the most widely supported 3D formats in existence. Beyond geometry it can reference materials through a companion .mtl file and store UV coordinates for textures, which makes it a go-to format for modeling, rendering and game engines.
This converter does the translation locally, in your browser: your file is read into a real 3D engine, shown so you can confirm it, then re-exported as a standards-compliant OBJ — no server, no account, no upload queue.
When to convert glTF to OBJ
Texturing & rendering
Open the OBJ in Blender, Substance or your renderer to add colour, PBR materials and textures the glTF could not hold.
Game & real-time assets
Engines such as Unity and Unreal prefer modeling, rendering, games formats. The converted OBJ fits straight into asset pipelines.
Editing & remeshing
Need to sculpt, retopologize or repair a model? Convert to OBJ so it opens in the tools that handle that best, then export again.
Sharing & interchange
OBJ is widely supported, making it a safe format for handing a model to a teammate, client or another application.
Your OBJ works everywhere
The exported OBJ imports cleanly into the major tools for modeling, rendering, games:
- Blender
- Maya
- 3ds Max
- ZBrush
- Cinema 4D
- Unity
Tips for the best glTF → OBJ results
- • Repair scans first. If your glTF came from a 3D scanner, run a quick mesh repair (Blender or MeshLab) to close holes before converting.
- • Expect a size change. OBJ is larger (readable text), so the output size may differ from your glTF — that's normal.
- • Check scale & orientation. Different tools assume different units. After importing the OBJ, confirm the model's size and up-axis match your scene.
- • Keep the original. Conversion is one-way here, so hold on to your source glTF in case you need to re-export with different settings.
Frequently asked questions
Is this glTF to OBJ converter free?
Yes — completely free, no sign-up and no watermark. The conversion runs entirely in your browser using WebGL, so your file never leaves your computer and there is no upload wait.
Does converting glTF to OBJ lose quality?
No — both formats store comparable data, so the geometry and materials are preserved and the conversion is effectively lossless.
What is the largest glTF file I can convert?
Because everything runs locally, the limit is your device's memory rather than an upload cap. Most models up to a few hundred MB convert smoothly on a modern laptop.
Where can I use the converted OBJ file?
OBJ is modeling, rendering, games. The exported file imports cleanly into Blender, Maya, 3ds Max, ZBrush and other OBJ-compatible tools.
Is it safe to convert private or proprietary models?
Yes. Nothing is uploaded — the file is read and converted on your own device, then the OBJ is generated locally for download. Your model stays private.
