Free normal map generator with live 3D preview

NormalMapAI (normalmapai.com) is a free online normal map generator that converts 2D photos into production-ready tangent-space normal maps and full PBR texture packs directly in your browser. Unlike server-side tools that require sign-up or add watermarks, this normal map generator runs 100% locally via WebGL2 and Canvas with instant PNG and ZIP export.

Upload your JPG, PNG, or WebP image into the NormalMapAI normal map generator, tune Normal Strength, Detail, and Height on the live 3D shader ball, and pick your target engine. Choose OpenGL (Y+) in the normal map generator for Blender, Unity, and Godot, or DirectX (Y-) for Unreal Engine 5, then export your normal map PNG or engine ZIP.

Choose OpenGL (Y+) in the normal map generator for Blender, Unity, Godot 4, and Three.js, where the green channel points up. Choose DirectX (Y-) in the normal map generator for Unreal Engine 5, 3ds Max, and DirectX-based pipelines, where the green channel points down.

To fix visible tile borders, enable Make Seamless or open the Seamless Texture tool before exporting from the normal map generator and verify repeating edges on a 2x2 or 4x4 grid. To sharpen blurry relief on brick, stone, or fabric, raise Normal Strength and Fine Detail inside the normal map generator while keeping pre-blur low.

A normal map generator encodes XYZ surface slopes in RGB channels so real-time shaders fake directional lighting on low-poly meshes without adding triangles. A bump map or height map stores single-channel grayscale elevation, whereas a displacement map physically moves subdivided vertices at render time to alter the silhouette.

Yes—NormalMapAI pairs a normal map generator with a multi-channel PBR pipeline that derives normal, 16-bit height, displacement, roughness, ambient occlusion (AO), metallic, and specular maps from one photo. You can inspect every channel in the normal map generator 3D viewport and download all maps together in one ZIP bundle.

Yes, every texture you create with the NormalMapAI normal map generator is 100% royalty-free for commercial games, archviz, VFX, and client projects. Because this normal map generator executes entirely inside your browser via local WebGL2 shaders, your proprietary source photos never leave your device.

The NormalMapAI normal map generator is a fast, zero-install browser alternative to discontinued Photoshop 3D filters, Materialize, and CrazyBump. This online normal map generator gives you real-time slope controls, OpenGL/DirectX Y-channel flipping, seamless tiling repair, and interactive 3D PBR preview on Windows, macOS, and Linux.

In the NormalMapAI normal map generator, rough brick, rock, and concrete look best with medium-to-high Normal Strength and balanced Detail for deep mortar grooves. Fine wood grain, leather, and woven fabric work best in the normal map generator with moderate Strength and crisp high-frequency Detail.

Export an OpenGL (Y+) PNG or Blender ZIP from the NormalMapAI normal map generator, load the normal map into an Image Texture node in Blender, and set Color Space to Non-Color. Pipe the color output into a Normal Map node (Tangent Space) and connect that to the Normal input of your Principled BSDF shader.

Yes, the NormalMapAI normal map generator exports at 512, 1024, 2048 (2K), and 4096 (4K) pixels. While color and normal maps export as 8-bit PNGs from the normal map generator, height and displacement maps export as 16-bit PNGs so deep relief stays free of stair-step banding.

Inverted lighting happens when the green (Y) channel orientation from your normal map generator does not match your game engine, or when sRGB color space is left turned on. Flip between OpenGL and DirectX in the normal map generator export preset, and mark the texture as Normal Map / Non-Color in your engine.
