GLB Optimizer
Trim a GLB without changing how it looks — lossless dedup, weld, resample and prune plus a validation report; Meshopt, quantization, simplification optional.
Processing and data safety
Section titled “Processing and data safety”This tool runs entirely in your browser — your files are never uploaded to a server.
Input and output
Section titled “Input and output”- Formats: GLB
- Flow: GLB → optimized GLB (dedup, weld, resample, prune)
How to use
Section titled “How to use”- Drop or select a .glb file — it is validated and previewed on the page.
- Toggle Meshopt compression, vertex quantization, mesh simplification (keep-ratio) or texture re-encoding as needed, then click Convert & download to regenerate with the current settings and save name-optimized.glb.
- Review the on-page validation report and export it as JSON or Markdown if needed.
Key details and limits
Section titled “Key details and limits”- Lossless by default: dedup, weld, resample and prune never change the visual result.
- Meshopt compression (EXT_meshopt_compression, includes its own quantization), vertex quantization (KHR_mesh_quantization), mesh simplification and embedded-texture re-encoding are optional, off by default, and lossy.
- Mesh simplification reduces every mesh towards the keep-ratio (not a guaranteed exact count); results depend on topology.
Common use cases
