Generate a normal map from an image

Turn a texture or heightmap into a tangent-space normal map for Unity, Unreal, Godot or Blender. Edges wrap, so tiling textures stay seamless.

Files are processed on your device and never sent to a server.

No sign-up, no watermark, no daily limits.

Works in Chrome, Edge, Firefox and Safari on desktop and mobile.

How it works

OpenGL or DirectX?+

Unity, Blender and Godot use OpenGL (Y+). Unreal Engine uses DirectX (Y−).

Should I use a color photo?+

It works, but a grayscale heightmap gives the cleanest result — bright means high.

Will it tile?+

Yes, the filter wraps around the edges, so a seamless texture gives a seamless normal map.

Make any texture tile without visible seams.

Convert PNG and JPG textures to KTX2 (Basis Universal ETC1S or UASTC) with mipmaps.

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.

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.

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

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