GLB to OBJ converter: the materials and the textures kept
Drop a .glb and get a zip with the .obj and its files, converted in Blender on our server. The trip keeps the materials and the textures; the skeleton and the skin weights, the shape keys and vertex colours cannot come along. Free, no account, nothing to install.
How do I convert GLB to OBJ?
Drop the file on this page, wait while the server converts it, and download a zip with the .obj and its files.
- 1Choose a .glb. Files up to 100 MB.
- 2The converter opens it in Blender on our server and writes OBJ. Most files take under a minute; the page shows the result in 3D when it is done.
- 3Download a zip with the .obj and its files. The upload and the result are deleted 3 days later.
- In:
- .glb / .gltf (zipped with its folder)
- Out:
- a zip with the .obj and its files
- Keeps:
- the materials and the textures
- Cost:
- free, no account
- The skeleton and the skin weights, the shape keys and vertex colours cannot be carried into OBJ.
What survives the trip
A GLB is glTF in one binary file: the scene, the meshes, the skin, the morph targets and the images, all inside. Draco and meshopt compression are unpacked on the way in. A .gltf with a .bin and a texture folder is taken as a zip of that folder.
The result is a zip with the .obj, its .mtl and the images the materials name, so unpacked into one folder it opens textured. OBJ has no room for a skeleton, shape keys or animation, so those stay behind.
GLB and OBJ do not hold the same things, and the page says so before you upload: the trip keeps the materials and the textures, and the skeleton and the skin weights, the shape keys and vertex colours cannot come along. OBJ is what every 3D program since the 1990s reads.
What this conversion cannot do
Measured on real files, not assumed. Everything below is a property of the formats or of the pipeline, and knowing it beforehand is cheaper than discovering it in your 3D tool.
A .gltf needs its folder
The text form of glTF names its .bin and its images by relative path. Uploaded alone it has no geometry to convert. Zip the folder that holds the .gltf, the .bin and the images and upload the zip.
No rig, no shape keys, no animation
OBJ stores a mesh and nothing that moves it. A skinned model is written in the pose its skeleton holds, as a statue; the bones, the weights and the blend shapes are not in the file because the format has no place for them.
Uploads stop at 100 MB
A larger file is refused before anything is uploaded. Decimate a dense mesh or shrink the textures in your 3D tool first; neither changes the format.
Frequently asked questions
GLB or glTF, which can I upload?
Both. A .glb is one file and goes in as it is. A .gltf is several files; put the .gltf, its .bin and its images in a zip and upload that.
Why is the download a zip?
Because a textured OBJ is several files: the .obj, the .mtl and the images. Unpack them into one folder and keep them together; the .obj finds its materials by relative path.
Is anything uploaded, and for how long?
Yes: the file you drop goes to our server in New York, is converted there, and both the upload and the result are deleted 3 days after the conversion. Nothing is shared with anyone.
Can I look at the GLB first?
Yes, without uploading anything: the GLB viewer draws it in your browser. Open the GLB viewer →
Can this become a VTuber avatar?
Not from OBJ: an avatar needs a skeleton, skin weights and a face that moves, and OBJ has no room for them. Convert the rigged source to VRM instead.

Is your model going into VTubing?
Converting because the model is going into VTubing? OBJ is not the format those apps read. The same rigged file becomes a VRM with its humanoid bones mapped and its materials converted, in one step on the FBX to VRM converter.
