Normal Map Generator

Turn a grayscale height map or texture image into a normal map preview for 3D materials, game assets, tileable textures, and design tests.

Choose a texture or height map image

Higher contrast source images produce stronger surface direction in the normal map.

What this tool does

  • Creates a tangent-space style normal map locally from a height map, grayscale texture, or high-contrast surface image.
  • No texture upload required, so quick material tests stay in the browser.
  • Exports PNG for Blender, Unity, Godot, web materials, and other texture workflows.
  • Useful as a fast preview step before refining strength, tiling, or seams in a full material editor.
  • Related local tools stay one click away when you need to compress or convert texture files before importing them.

FAQ

What kind of image works best?

Height maps, grayscale textures, and high-contrast surface photos usually produce the clearest normal maps.

Is this a replacement for a full material editor?

No. It is a quick browser tool for generating and testing a normal-map starting point.

Can I use the PNG in a game engine?

Yes. The downloaded PNG is intended as a normal-map starting point for engines and 3D tools, but you should preview lighting and strength in your target material setup.

Does it work with color textures?

Yes. The tool can read a color texture, convert brightness into height-like information, and generate a normal-map preview from that contrast.
