Fix scale, axes and pivot

Models from CAD, 3D printing or other engines often come in the wrong units or lying on their side. Fix it once and download a clean file.

How it works

Why is my model 100× too big?+

It was probably exported in centimeters or millimeters. Pick the right source unit to convert it to meters.

Why is it lying on its side?+

CAD and 3D-printing tools use Z-up; game engines use Y-up. Choose “Z” as the up axis.

Where should the pivot be?+

For trees, rocks and props — at the bottom center, so they stand on the ground when placed.

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

Reduce triangle count of any model while keeping its shape.

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

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.
