Stored locally in your browser (IndexedDB).
Reduce polycount while preserving silhouettes. Vertices are merged based on surface curvature and UV seams.
Convert heavy 8K textures to WebP or KTX2/Basis. Automatic resizing and normal map optimization.
Industry-standard geometry compression that works out of the box with Three.js, Babylon.js and React Three Fiber.
Animations, materials, UVs and hierarchy stay intact. Transparency and PBR fidelity are protected.
See file size, triangle count, draw calls and estimated load time — measured, not guessed.
Unused nodes, duplicate meshes and stale metadata removed. Everything packed into a single ready-to-ship .glb.
Skip the 50-parameter export dialog. Pick where your model is going and we tune geometry, textures and materials for that target.
Fast first paint in the browser.
Light enough for product pages, validated by Shopify.
iOS, Android, WebAR — fast on cellular.
When every kilobyte counts.
Try it on one file.
One heavy file, fully optimized.
For agencies and 3D shops.
Volume + automation.
No. We preserve PBR materials, UVs, transparency and animation tracks. Optimization happens on geometry and texture data — not on what the renderer needs to display your model correctly.
GLB and GLTF (with external textures bundled). Output is always a single ready-to-ship .glb file.
Yes. The Shopify preset enforces Shopify's recommended limits (under 20 MB, textures ≤ 2K) and produces a GLB that uploads cleanly to product pages.
Files never leave your browser — everything runs locally. We don't store or upload anything.
Up to 200 MB per file. The free tier includes one conversion; paid plans unlock unlimited optimizations.
