NormalMapAI is a free, zero-login normal map generator and PBR texture maker built on in-browser WebGL2. Drop a 2D photo to generate tangent-space normal maps (OpenGL +Y and DirectX -Y), 16-bit height/displacement, roughness, AO, metallic, curvature, specular, emissive, and packed ORM maps. Includes a seamless tileable texture maker, transparent PNG background remover, and a live 3D preview (sphere, cube, plane, cylinder, torus) with export presets for glTF, Blender, UE5, and Unity. Every pixel stays on device.
