Normal to Height Map

Free Normal to Height Map Converter

Convert any OpenGL normal map to a precise displacement / height map online, completely free and without registration. Our converter uses Frankot-Chellappa Poisson reconstruction (an FFT-based height-from-gradient algorithm) to estimate the underlying surface from a normal map's X and Y gradients. Result is exported as an 8-bit or true 16-bit grayscale PNG, ready for displacement and parallax mapping in Blender, Unreal Engine, Unity, 3ds Max, Maya, and any PBR workflow.
