Reduce Polys
Lower the triangle count of GLB and glTF models while keeping UVs, normals and material edges intact. Presets or a custom target, wireframe preview, and nothing is uploaded. Takes FBX too, converted to GLB in your browser.

How to reduce the polygon count of a 3D model
Reduce Polys lowers the triangle count of a GLB or glTF model while keeping its shape, so it renders faster in games, on mobile, in WebGL and in VR. It uses mesh simplification that can protect material boundaries, UV seams and normals, so textures stay where they belong.
Choose a Light, Medium or Heavy preset or set your own target, then check the simplified mesh and its wireframe before downloading. It all runs in your browser, with nothing uploaded.
Step by step
- Drop a .glb or .gltf model onto the page.
- Choose a preset or set a custom reduction target.
- Check the new triangle count and the wireframe preview.
- Download the reduced GLB.
Questions
How many polygons should a game model have?
It depends on the platform and how big the object appears on screen. As a rough guide, small props on mobile often sit in the hundreds to a few thousand triangles, and hero characters in the low tens of thousands. On desktop and console the budgets are much higher. Check your engine and target hardware rather than relying on one number.
Will reducing polygons break my textures?
Protecting UV seams and material boundaries keeps textures mapped correctly. Very heavy reductions can still soften fine detail, so compare the result with the original before you use it.
Does it work on animated or rigged models?
The simplifier can keep skinning data (joints and weights), morph targets and animations. Heavily reduced rigged meshes can deform less cleanly, so test the result in your engine.
What is the difference between reducing polys and generating LODs?
Reduce Polys makes one lighter version of your model. Generate LODs makes several versions at different detail levels, so an engine can swap to a simpler one as the object moves further away.
