GenPBR is a free height map generator and heightmap generator that derives elevation from your source texture. Use it as a height map maker for displacement-friendly grayscale—upload on /generate, tune height with other PBR channels, and export PNG.
Height map from image
For “height map generator from image,” “heightmap generator from image,” or “image to height map” searches, the path is the same: upload your albedo or reference plate, adjust height intensity in the 3D preview, export PNG. Pair with the normal map generator, roughness map generator, and metallic map generator.
Heightmap generator online
Searches for heightmap generator online or heightmap generator (one word) land here—the same free browser tool on /generate. No install, instant 3D preview, and PNG export for displacement, parallax, or height-blend shaders.
Grayscale height maps for engines
A grayscale height map generator output works for Unity HDRP height inputs, Unreal displacement, Blender displacement modifiers, and similar pipelines. GenPBR gives a strong first pass you can normalize or clamp in-engine.
Full PBR hub
For the complete workflow, use image to PBR and the texture map generator hub. Create a free account for 4K exports and bulk processing when volume grows.
