Normal Map Bench
Free browser-local normal map generator — turn a height texture into a clean tangent-space normal map, inspect it under movable light, export PNG. No upload, no account.
What is Normal Map Bench?
Normal Map Bench is a free, browser-local normal map generator for 3D artists and game developers. Drop in a height texture (PNG / JPG / WebP) and get a clean tangent-space normal map in seconds. Inspect the result live under a movable light, then tune it with strength, smoothing and gradient filters (Sobel or Scharr) until the surface reads right. Export a free PNG in OpenGL (Y+) or DirectX (Y-) format, ready for game engines and material workflows. Everything runs locally in your browser: your texture never leaves the machine, no upload queue, no account, no remote processing. Open the page and start converting — that's the whole workflow.
