3D & CAD converter · runs 100% in your browser
GLB to OBJ Converter
Extract Wavefront OBJ geometry from a glTF binary (.glb) file. Walks the scene graph, applies world transforms, emits a single OBJ with all meshes flattened. Materials are dropped — OBJ doesn't carry them inline. Runs entirely in your browser.
How to use
- Drop your GLB file.
- three.js parses the geometry locally.
- OBJ output is encoded in browser memory.
- Click Download.
FAQ
Are textures embedded?
OBJ does not embed textures inline. Use the matching .mtl file alongside if you need materials.
Does my 3D model upload to a server?
No. Conversion runs entirely in your browser using WebAssembly and Web APIs. Open the Network tab in DevTools while you convert — you'll see no outbound traffic carrying your file.
Is this really free?
Yes. No signup, no quota, no upgrade tier. The conversion runs on your machine, so it costs us nothing to host.
Is there a mesh size limit?
Browser memory is the only ceiling. On a modern desktop browser, a few hundred megabytes works fine. Mobile devices have tighter limits.
