Compress GLB And GLTF Files Without Uploading Them
Optimize 3D models directly in your browser. Reduce geometry and texture weight, compare results, and download an optimized GLB ready for delivery.
Upload your 3D asset
Start with a GLB, a single GLTF, or a ZIP package that contains a GLTF scene and its dependencies.
Choose a file to optimize
Supported formats: GLB, GLTF
ZIP upload is accepted for GLTF packages with external BIN or texture files.
Privacy-first compression
Files stay on-device. The compressor runs in your browser and avoids server-side uploads for the MVP flow.
Texture and geometry optimization
Tune texture format, quality, and texture size while applying geometry cleanup and quantization for smaller assets.
Built for web delivery
The output is optimized for web publishing, preview handoff, and downstream use in your existing viewer workflow.
A narrower tool, but a faster path to production assets
Instead of handling every 3D format, the compressor starts with the formats that matter most for web delivery. That keeps the first version focused, testable, and genuinely useful.
