OBJ to GLB converter

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

Convert the attached OBJ file to GLB

Files are processed entirely in your browser. Nothing is uploaded to a server.

Any 3D edit is just a prompt away.

How the conversion works

OBJ is a text-based mesh format from the DCC world (Blender, Maya, ZBrush). It can reference materials through a separate .mtl file; this tool reads the geometry.

The converter writes GLB, so the result loads directly in web viewers, e-commerce embeds, and most game engines.

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 OBJ to GLB conversion?

Geometry comes through completely: every triangle, at full precision. Materials, textures, and vertex colors don't, because the pipeline works on plain geometry. The GLB you download is ready to texture in Blender or a web viewer.

Is there a file size limit?

Models up to 8 million triangles work. STL files can be any size below that; other formats stop at 300 MB. Heavier meshes take longer rather than failing outright; if a file is unwieldy, reduce its triangle count first with the reduce tool.
