Polygon reduction is the problem 3D workflows hit every day – game engines need a triangle budget, web 3D and AR load faster with fewer polygons, and slicers choke on dense scans. Decimify reduces polygon count in your browser while keeping UV seams and material boundaries clean. Free for basic use; sign in with a 3dshouse account for Pro.
Features
- Real-time slider – the whole LOD pyramid is computed once, then scrubbed instantly with no rebuild.
- Attributes stay intact – UV seams, normals, and material boundaries survive every reduction level.
- GLB / STL / USDZ – GLB keeps materials and textures; STL for 3D printing; USDZ export for AR Quick Look.
- Off the main thread – WebAssembly + a background worker keep the UI responsive on million-triangle models.
- Private by design – files are parsed in-browser; no upload, no account needed for the free tier.
Install
Nothing to install – it runs in any modern browser. Sign in with your 3dshouse account to unlock Decimify Online Pro.
Requirements
- Any modern browser (Chrome, Edge, Firefox, Safari).
- WebAssembly support (standard on current browsers).
FAQ
What formats can I use?
Import GLB or STL; export GLB (with textures), STL, or USDZ. Convert other formats to GLB in Blender first.
Is my model uploaded?
No – everything runs in your browser. No upload, no account for the free tier.
Is there a SketchUp version?
Yes – the Decimify SketchUp plugin simplifies geometry in place while keeping groups, components, and soft edges.
