NormalMapAI — Free Online Normal Map & PBR Texture Generator

NormalMapAI (https://normalmapai.com) 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 instantly 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. It also 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/UE5/Unity export presets. Every pixel is processed 100% locally in the browser so textures never leave your device.

Pricing is Free: 100% free in-browser, no login required. The public site is https://normalmapai.com/.

Core capabilities

NormalMapAI turns one 2D image into a production PBR set. Outputs include tangent-space normal maps in both OpenGL (+Y) and DirectX (−Y), 16-bit PNG height and displacement maps, roughness, ambient occlusion, metallic, curvature, specular, emissive, and channel-packed ORM maps. A seamless tileable texture maker and a transparent PNG background remover cover decals and sprites. The live 3D preview can show a sphere, cube, plane, cylinder, or torus under HDRI or point lighting, with export presets for glTF, Blender, Unreal Engine 5, and Unity.

Engine workflows

In Blender, connect the normal map through a Normal Map node into Principled BSDF, send the 16-bit height or displacement map to a Displacement node, and plug roughness, metallic, and AO into the matching sockets. In Unreal Engine 5, use the DirectX −Y normal and assign the ORM pack (occlusion, roughness, metallic) on the material. In Unity, place the maps on a URP or HDRP Lit shader and match the normal import typ
