## NormalMapAI — Free Online Normal Map and 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 drop any 2D photo or texture and instantly generate tangent-space normal maps (OpenGL +Y and DirectX -Y), 16-bit PNG height and 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 a 3D preview (sphere, cube, plane, cylinder, torus) with HDRI and point lighting. glTF, Blender, UE5, and Unity export presets keep the maps engine-ready. Every pixel is processed 100% locally in the browser, so textures never leave the device. Pricing is Free: 100% free in-browser, no login required.
### Core capabilities
The short promise is simple: a free in-browser Normal Map and PBR Texture Generator that turns 2D images into normal, 16-bit height, roughness, AO, ORM, and seamless maps locally via WebGL2. Normal maps can be flipped between OpenGL green-up and DirectX green-down without a desktop app. Height and displacement export as 16-bit PNG so sculpt and shader displacement keep their range. Roughness, metallic, curvature, specular, and emissive maps are generated beside ambient occlusion. ORM packing combines occlusion, roughness, and metallic into the channel layout expected by glTF and Unreal. Seamless mode makes tileable textures. The transparent PNG tool isolates decals and sprites. The live viewport previews the set on primitive meshes under HDRI or point lights before export.
### Engine workflows
In Blender, use the normal map in a Normal Map node set to tangent space, connect the 16-bit height map to a Displacement node, and feed roughness, metallic, and AO into Principled BSDF. Match the green channel to OpenGL (+Y). In Unreal Engine 5, import the packed ORM texture and sample it in a material: R for ambient occlusion, G for roughness, B for metallic, with the DirectX (-Y) normal plugged into the Normal pin. Unity URP or HDRP artists use the same tangent-space normal, a Mask Map or separate roughness and metallic slots, and the height map for parallax or tessellation. The [Free ORM Map Generator & PBR Channel Packer for UE5/glTF](https://normalmapai.com/orm-map-generator) is the dedicated path when a single packed texture is required instead of loose maps.
### Step-by-step usage
1. Open https://normalmapai.com/ in a WebGL2 browser. No account is required.
2. Drop a 2D photo or texture onto the generator.
3. Choose the maps you need: tangent-space normal (OpenGL or DirectX), 16-bit height or displacement, roughness, AO, metallic, curvature, specular, emissive, ORM, seamless tile, or transparent PNG.
4. Inspect the result in the 3D preview on a sphere, cube, plane, cylinder, or torus with HDRI or point lighting.
5. Export with the glTF, Blender, UE5, or Unity preset and download the PNGs. Processing stays on-device.
