Reduce polygons of a 3D model

Decimate heavy models for games, the web or AR. The simplifier keeps the silhouette and UV seams while removing triangles.

How it works

How far can I reduce?+

Organic models usually look fine at 20–30%; for distant LODs you can go down to 5%.

Are UVs and textures kept?+

Yes — UVs are preserved, so textures still fit after reduction.

What is “lock borders”?+

It keeps open edges in place — useful for terrain tiles and modular pieces that must line up.

Shrink GLB files: Meshopt geometry, WebP or KTX2 (Basis) textures.

Generate LOD0–LOD4 from one model, named for Unity and Unreal.

Fix units, Z-up/Y-up and the pivot of a model before import.

Check GLB and glTF files with the official Khronos validator.

Open GLB, FBX, OBJ, STL and 20 more formats; LODs, variants, stats.

Convert FBX, OBJ, STL, GLB, DAE, 3MF, USDZ and more to GLB, glTF, OBJ, STL, PLY or USDZ.

Render a model from 4, 8 or 16 directions into a sprite sheet for 2D games.

Record a spinning video of a 3D model for stores, portfolios and trailers.

FoliMesh generates vegetation and rocks with LOD0–LOD3, collision and a pivot at the base — GLB, FBX or OBJ for any engine.
