Simplify

3D Mesh Simplifier

Cut polygon count while keeping the shape that matters. Preview the result live, then export in your target format.

Crunch a mesh

Upload your model once and it stays in your library — simplify it, compare the result against the original in a full-size viewer, then re-crunch it with different settings whenever you like.

Auto or targeted

Let auto find the smallest mesh that stays within a geometric error budget, or set a reduction percentage or triangle budget yourself.

See what changed

Switch between original and optimized without the camera moving, with triangle, vertex, and file-size reductions side by side.

Processing survives a refresh

Jobs run on our servers, not in your browser. Close the tab, come back later, and the result is waiting.
