If you searched for png to normal map, you likely have a flat color plate in PNG and need tangent-space normals without desktop software. GenPBR converts PNG (and JPG/WebP) to normal maps in your browser with live 3D preview before export.

For the broader “normal map generator,” “normal map maker,” or “image to normal map” workflow, use the normal map generator page as the main hub, then open /generate to create maps. Diffuse-specific plates can start from diffuse to normal map.
Pair with other PBR channels
Normals rarely ship alone. After export, pair with the roughness map generator, metallic map generator, and height map generator from the same source session on /generate.
