GLB Vertex Compression

Vertex compression reduces the number of vertices (and thus polygons) in your 3D model while preserving its overall shape. Combined with Draco encoding, this can dramatically reduce file size.

No. Meshopt mesh simplification permanently removes polygons, so the process cannot be reversed. Always keep a backup of the original model. Use the real-time preview to evaluate quality before downloading the compressed result.

Typical reduction is 50-90% depending on the model complexity and settings. Models with high polygon counts achieve the best results with Draco encoding.

Lower strength preserves more detail but results in larger files. You can preview the compressed model before downloading to find the right balance.

Draco is an open-source library for compressing and decompressing 3D geometric meshes and point clouds. It can reduce mesh sizes by up to 90% while maintaining visual fidelity.

Yes! Three.js has built-in support for Draco-encoded GLB/GLTF files. You just need to include the Draco decoder in your project.

Start with a low ratio (0.2–0.4) for moderate reduction, then increase gradually while previewing. For web display, 0.5–0.7 is often acceptable. For high-detail requirements, stay below 0.3. Always preview before committing to ensure visual quality meets your needs.
