About NormalMap

NormalMap is a free, browser-based normal map generator for 3D artists, game developers and designers. Upload a height map, bump map or photo and get a tangent-space normal map you can drop straight into Blender, Unity, Unreal Engine, Godot or any PBR pipeline.

Everything is computed locally in your browser with a Sobel gradient - your images are never uploaded, stored or transmitted. There is no sign-up, no watermark and no queue.

Alongside the generator you will find practical guides on normal maps, bump maps and material setup, so you can go from a flat texture to a light-responsive surface in minutes.
