NormalMapAI is a free, zero-login online Normal Map Generator and full PBR Texture Maker. The tool runs on in-browser WebGL2 GPU shaders. Artists, game developers, and 3D printing creators drop any 2D photo or texture and generate maps without creating an account and without uploading files to a server. Every pixel is processed 100% locally in the browser so textures never leave your device.         Core capabilities. The generator builds tangent-space normal maps in both OpenGL +Y and DirectX -Y. From the same source image it can produce 16-bit PNG height and displacement maps, roughness, ambient occlusion (AO), metallic, curvature, specular, emissive, and channel-packed ORM maps. A seamless tileable texture maker turns a source into a repeating texture. A transparent PNG background remover prepares decals and sprites. An interactive 3D preview viewport shows the result on a sphere, cube, plane, cylinder, or torus, with HDRI and point lighting. Export presets cover glTF, Blender, Unreal Engine 5, and Unity. Pricing is Free: 100% free in-browser, no login required.         Blender workflow. Generate an OpenGL +Y tangent-space normal map, a 16-bit height or displacement map, roughness, and ambient occlusion, then use the Blender export preset. The live 3D preview on a sphere, cube, plane, cylinder, or torus lets you check HDRI or point lighting before you leave the browser. Source textures are not uploaded.         Unreal Engine 5 workflow. Choose the DirectX -Y normal map when the project expects that green-channel convention, and pack occlusion, roughness, and metallic into an ORM map. The UE5 export preset matches that packed workflow. Preview the material under HDRI or point lighting in the browser viewport before export.         Unity workflow. Use the Unity export preset together with the normal, height, roughness, AO, and metallic outputs you need. The same local WebGL2 session can also make a seamless tileable texture or a transparent PNG for decals and sprites.         Step-by-step usage. Open NormalMapAI in a WebGL2 browser. No login is required. Drop a 2D photo or texture into the generator. Generate tangent-space normals (OpenGL +Y or DirectX -Y), 16-bit height or displacement, roughness, AO, metallic, curvature, specular, emissive, or a packed ORM map. Optionally make a seamless tileable texture, or remove the background for a transparent PNG decal or sprite. Inspect the material in the 3D preview, then export with the glTF, Blender, UE5, or Unity preset. The image never leaves your device.         FAQ. Is NormalMapAI free? Yes. It is 100% free in the browser and does not require a login. Do textures get uploaded? No. Every pixel is processed locally with WebGL2 GPU shaders, so textures stay on your device. Which engines are supported? Export presets are included for glTF, Blender, Unreal Engine 5, and Unity. Can I make tileable textures and decals? Yes. The seamless tileable texture maker and the transparent PNG background remover are part of the same free tool. Where can I generate an ambient occlusion map?
