Lossless GLB optimize (dedup + weld + resample + prune), glTF/GLB validation report, and optional embedded-texture downscale. Locally processed.

Vertex quantization (lossy, KHR_mesh_quantization, big size win)Optimize embedded textures (Canvas)

Textures are only replaced when re-encoding yields a smaller file; otherwise the original is kept.

What is it? GLB Optimize performs lossless clean-up on a GLB: it deduplicates and welds vertices, resamples animation tracks and prunes unused data to reduce size without changing the visual result.

TL;DR: Lossless GLB clean-up: dedup, weld, resample, prune.

FAQ

Is it truly lossless?

It removes duplicate/unused data and welds coincident vertices; visual geometry is preserved.

Does it change textures?

No — textures are kept as-is.

Limitations

May not help models that are already clean.
Compression of geometry requires the Draco tool.
