Convert GLB to OBJ
Drop in a .glb or .gltf and get an .obj back, ready for Blender, ZBrush, Maya, or any tool that predates glTF. The conversion runs on your machine.
Drop a GLB file
or click to choose one. Your file never leaves your browser.

What carries across
Vertex positions, normals, and UV coordinates all survive the conversion, so the model
arrives in your editor with its shape and texture mapping intact. What does not carry is
the material definitions themselves: OBJ keeps those in a separate .mtl file
that references external image files, and this tool emits the geometry only.
In practice that means you will see the correct shape with correct UVs, and you reassign the texture maps from the original GLB in your editor. For most retopology and sculpting work that is exactly what you wanted anyway.
When to use OBJ instead of GLB
- Older or CAD-adjacent tools that never added glTF support.
- Scripting and inspection: OBJ is plain text you can read and diff.
- Sculpting round-trips where you only care about the mesh.
If your destination accepts GLB, keep GLB. It is smaller, and it carries materials, textures and animation in a single file rather than a folder of loose assets.
No 3D model yet?
Turn a single product photo into a realistic 3D model, usually in about 5 minutes. Explore it, view it in AR at real size, embed it, or export it to any of 7 formats. Pay as you go from $5, no subscription.
Frequently asked
Does the OBJ include materials and textures?
The geometry and UV coordinates come across, but this tool writes the .obj only, not the companion .mtl material file or the texture images. Your editor will open the shape with correct UVs and you can reassign materials there.
Why convert to OBJ rather than keep GLB?
Older pipelines and some CAD and sculpting tools read OBJ but not glTF. OBJ is also plain text, so it is easy to inspect or script against. If your target application accepts GLB, keep GLB: it carries materials, textures and animation in one file.
Is anything uploaded?
No. The file is parsed and re-exported in your browser. Nothing is sent to a server and there is no sign-up.
What happens to animations?
They are dropped. OBJ is a static format with no concept of skinning or keyframes, so you get the mesh in its rest pose. Keep the original GLB if you need the animation.
