Converting Wavefront OBJ to glTF Binary (GLB)

OBJ is a portable, widely edited mesh format, but it often needs a separate .mtl file and isn't ideal for the web. GLB bundles everything into one binary that browsers, AR and game engines read natively. Converting OBJ to GLB gives you a single, web-ready file.

What's kept and what's dropped

Mesh geometry and UV coordinates convert across. Materials from a linked .mtl aren't loaded here, so the GLB carries the mesh with a standard material — reassign textures afterward if needed.

OBJ to GLB — FAQ

Is the OBJ to GLB converter free?
Yes, free with no sign-up and no limits.
Is my OBJ uploaded anywhere?
No — it's converted locally in your browser and stays on your device.
Why convert OBJ to GLB?
To use a model on the web or in AR, or to hand a game engine one self-contained file instead of an OBJ + .mtl pair.
Are textures included in the GLB?
The mesh and UVs convert; external OBJ textures aren't packaged in. Keep them alongside or re-apply them in your tool.
