Create, view and optimize GLB models in your browser

Polynite opens a .glb file, draws it with WebGPU, and makes it smaller. The file is read by this page and stays on your machine.

What it does

• Open GLB files, with no upload and no account. OBJ and text glTF are read too.
• Inspect triangles, materials, textures, normals, UVs and level of detail.
• Reduce the polygon count with an error driven simplifier that respects UV seams.
• Compress geometry with Meshopt and resample oversized textures.
• Compare the original and the optimized model side by side before exporting.

Drop a model into the window to begin, or pick one of the bundled examples.
