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 silhouette, UVs, and normals. Ship lighter models without the visible cost.
Open tool →LOD Generation
Produce a full LOD chain in one pass — LOD0 through LOD5 — with per-level budgets tuned for distance-based swapping in your engine.
Open tool →Format Conversion
Convert between OBJ, STL, GLB/glTF, PLY, FBX, 3MF, DAE and USDZ. Sensible defaults for game, web, and 3D-print pipelines.
Open tool →How it works
Upload
Drag in your model — up to 2 GB on paid plans. Nothing leaves your browser until you hit process.
Configure
Pick a target detail level, LOD count, or output format. Preview the mesh live in 3D.
Crunch
We decimate or convert on the server and return an optimized file, ready to ship.
Every format you ship
Import from the tools you already use; export to the format your target runtime wants.
