What is GLTF?
glTF (GL Transmission Format) is the open standard for 3D assets on the web, developed by the Khronos Group. A glTF scene consists of a .gltf JSON file, one or more .bin files with geometry data, and separate texture image files.
Why optimize GLTF?
Separate glTF files (.gltf + .bin + textures) are fragile and typically uncompressed. Optimization packs everything into a single GLB file and applies meshopt compression, texture optimization, and geometry deduplication — dramatically reducing total file size and improving loading speed.
What gets optimized?
Trice packs separate glTF files into a single GLB, applies meshopt compression, converts textures to WebP, resizes oversized textures, and deduplicates identical geometry and materials.
How it works

Drag and drop or click to select your GLTF model.
Auto-optimize
Trice compresses meshes, optimizes textures, and deduplicates geometry — all in your browser.

Frequently asked questions
If your glTF has separate .bin and texture files, yes — put the .gltf, .bin, and all texture files into a ZIP archive, then drop the ZIP here. Trice will resolve all file references automatically.
No. The optimization is lossless for geometry. Textures are converted to high-quality WebP with no visible difference. All materials, animations, and scene hierarchy are preserved.
Yes. The optimized output is always GLB — a single binary file that bundles everything together. This is more efficient and easier to share than separate glTF files.
Significant reduction. Packing alone eliminates overhead from separate files. Meshopt compression reduces geometry by 60-90%, and texture optimization adds another 70-95% reduction on texture data.
