NormalMapAI

NormalMapAI is a free, zero-login online Normal Map Generator and full PBR Texture Maker built on in-browser WebGL2 GPU shaders. Artists, game developers, and 3D printing creators can drop any 2D photo or texture to generate tangent-space normal maps (OpenGL +Y and DirectX -Y), 16-bit PNG height/displacement maps, roughness, ambient occlusion (AO), metallic, curvature, specular, emissive, and channel-packed ORM maps.

Core capabilities
NormalMapAI includes a seamless tileable texture maker, a transparent PNG background remover for decals and sprites, and an interactive 3D preview viewport (sphere, cube, plane, cylinder, torus) with HDRI/point lighting and glTF, Blender, Unreal Engine 5, and Unity export presets. Every pixel is processed 100% locally in the browser, so textures never leave the device. Pricing is free, and no login is required.

Engine workflows
In Blender, use a 16-bit height or displacement map with a tangent-space normal map in the Shader Editor, or pack channels with the ORM map output. In Unreal Engine 5, use the DirectX -Y normal map and an ORM packed map on a standard material. In Unity, use the OpenGL +Y normal map with roughness and ambient occlusion on the Standard, URP, or HDRP material.

How to use
Open the tool in a WebGL2 browser, drop a 2D photo or texture, generate the maps, check them in the live 3D preview, and download PNG outputs, including 16-bit height maps and transparent PNGs.
