Free height map generator — heightmap from images

Create grayscale, displacement-ready heightmaps from one upload. Use as a height map maker alongside normals, roughness, and metallic for a coherent PBR material.

Free · No signup for core use · 3D preview · Browser-based · Unity, Unreal, Blender & Roblox

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. Pair with the normal map generator, roughness map generator, and metallic map generator.

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.
