Crunch heavy 3D models into fast, shippable assets.
MeshCrunch simplifies meshes, generates LOD chains, and converts between every major 3D format — so your games, web scenes, and XR apps load in a fraction of the time.
One toolkit for the whole 3D pipeline
Purpose-built for optimizing polygon-heavy assets before they reach real-time renderers.
Mesh Simplification
Reduce triangle count with quadric-error decimation while preserving the silhouette. See exactly how many triangles and how much file size you saved.
Open tool →Turntable Export
Spin any model into a shareable GIF or MP4 — rendered entirely in your browser, nothing uploaded, no account needed.
Open tool →LOD & Conversion
Level-of-detail chains and format conversion between OBJ, STL, GLB, glTF, PLY and OFF. In development — preview works today.

Upload
Drag in your model — up to 50 MB free, 1 GB on Pro. It previews locally before anything is sent.
Configure
Let auto mode find the smallest mesh that still looks right, or set a target detail level yourself.
Crunch
We decimate on the server and return an optimized file, with a before-and-after breakdown.
Every format you ship
Import from the tools you already use; export to the format your target runtime wants.
