GLB to OBJ converter

Drop a GLB file, check the preview, download OBJ. The conversion runs in your browser, so your model never leaves your device.

How the conversion works

GLB is the binary form of glTF, the standard format for web and real-time 3D. A single file holds meshes, materials, and textures.

The converter writes a plain OBJ that imports cleanly into Blender, Maya, and most game engines, which makes it a practical handoff format for further editing.

One thing to watch: glTF stores coordinates in meters, while OBJ is usually read as millimeters. If your model arrives 1000 times too small, tick the meters-to-millimeters option before converting.

Frequently asked questions

Does my file get uploaded?

No. Parsing and export run in your browser with WebAssembly and three.js. The file stays on your device, and it works offline once the page has loaded.

What survives the GLB to OBJ conversion?

Geometry comes through completely: every triangle, at full precision. Materials, textures, and vertex colors are dropped, because OBJ as written here stores plain triangles only.

Is there a file size limit?

Files up to 150 MB work. Heavier meshes convert too, they just take longer; if a file is unwieldy, reduce its triangle count first with the reduce tool.
