What is GLB?
GLB (GL Binary) is the binary version of glTF — the standard 3D format for the web, developed by the Khronos Group. GLB bundles geometry, materials, textures, and animations into a single compact file. Supported by all modern browsers, game engines, and 3D tools.
Why optimize GLB?
Even though GLB is already a compact format, most GLB files exported from 3D tools contain uncompressed meshes, oversized textures, and redundant geometry. Optimization with meshopt compression, texture resizing, and deduplication can reduce file size by 60-95% — making your models load dramatically faster on the web.
What gets optimized?
Trice applies meshopt vertex reordering for GPU cache efficiency, quantizes geometry precision where invisible, converts textures to WebP, resizes oversized textures, and deduplicates identical geometry and materials across the scene.

Frequently asked questions
Depends on the model. Mesh compression alone reduces geometry by 60-90%. If your GLB has large textures, texture optimization can cut file size by an additional 70-95%. A 150 MB GLB can easily become 10 MB or less.
No. Meshopt compression is lossless for geometry — every polygon is preserved. Texture optimization uses high-quality WebP encoding that is visually indistinguishable from the original in virtually all cases.
Yes. All animations — skeletal, morph targets, keyframes — are fully preserved. The optimizer handles rigged models carefully to avoid breaking bone influences.
Yes. Trice will detect existing compression and apply additional optimizations where possible — such as texture optimization and geometry deduplication — without double-compressing already compressed data.
