Free 3D File Converter
glTF to OBJ Converter
Drag in a .gltf file, see it in 3D, and download a clean .obj in seconds — right in your browser. No upload, no sign-up. Self-contained glTF files up to 25 MB are supported; the OBJ download contains mesh data but no MTL or texture package.
Your download is ready. Keep working with the converted file:
- ✓ 100% free
- ✓ Private — nothing uploaded
- ✓ Instant, in-browser
- ✓ No sign-up

glTF vs OBJ: what's the difference?
| Feature | glTF | OBJ |
|---|---|---|
| Geometry (mesh) | Loaded | Written |
| Normals | When present | Written |
| UV coordinates | When present | Written |
| Materials | Embedded glTF materials | No MTL output |
| Texture images | Embedded only | Not included |
| Animation / rigging | May be present | Not included |
| Scene hierarchy | May be present | Flattened to OBJ objects |
| Limit / download | 25 MB input | One .obj file |
What is the glTF format?
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 the OBJ format?
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): 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.
Use this route when an application needs OBJ mesh data. It writes vertices, faces, normals and available UV coordinates, but it does not generate an MTL file or texture package. Animation, rigging and scene hierarchy from glTF are not carried into the OBJ download.
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
Geometry-first handoff
Send one readable OBJ mesh to an application that does not accept glTF. Plan to rebuild or relink materials and textures after import.
Modeling and mesh edits
Open the OBJ geometry in Blender, Maya, ZBrush or another modeling tool for sculpting, retopology and mesh cleanup.
Static asset exchange
Use OBJ when the destination needs a static mesh and does not require glTF animation, rigging or scene hierarchy.
Broad OBJ compatibility
Share geometry with older tools and pipelines that support OBJ, while keeping the original glTF as the material and scene source.
Open the OBJ output
The OBJ geometry can be opened in these tools. Rebuild or relink materials and textures after import:
- 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.
- • Plan materials separately. The download is one OBJ file. Rebuild or relink materials and textures after import because this route does not create MTL or image files.
Frequently asked questions
Is this glTF to OBJ converter free?
Yes — completely free, no sign-up and no watermark. The conversion runs locally in your browser, so your file never leaves your computer and there is no upload wait. The optional 3D preview uses WebGL when available, but conversion does not depend on it.
Does converting glTF to OBJ lose quality?
The OBJ keeps mesh geometry, normals and available UV coordinates. This download does not include an MTL file, texture images, animation, rigging or glTF scene hierarchy, so keep the original glTF and check the OBJ in your destination application.
What is the largest glTF file I can convert?
This route accepts glTF files up to 25 MB. Conversion runs locally, so a dense model below that limit can still exceed the memory available on a phone or older computer. Simplify very large assets in a desktop 3D application first.
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.
