When you need this
You have an OBJ from a modeling tool or an asset library and need a GLB for the web — a three.js / React Three Fiber viewer, an AR quick-look, a game engine, or an AI pipeline that speaks glTF. GLB packs your mesh into one compact binary file that browsers load fast.
OBJ to GLB — FAQ
Will my .mtl materials and textures carry over?
This pass converts geometry and UVs — it doesn’t bundle the .obj’s .mtl file or texture images into the GLB. Reassign materials in your web or 3D tool after import.
Why GLB instead of glTF?
GLB packs everything into a single binary file — simpler to host and load than glTF’s separate .gltf + .bin + textures. Most web viewers and AR tools expect GLB.
Is my OBJ uploaded anywhere?
No. The converter runs locally in your browser tab; your file never leaves your device.
