Normal Map Bench

Normal Map Bench turns a height texture into a clean tangent-space normal map — entirely in your browser. Upload nothing: the whole conversion runs locally, so source textures never leave your device. Choose Sobel or Scharr gradient filters, tune smoothing and strength, switch between OpenGL and DirectX orientation, inspect the result under a movable light, and export a PNG your renderer can read. Free, no account, no queue. Built for game developers and 3D artists who need a quick, private normal map from a photo or painted texture.
