FAQ
How do I convert a height map or displacement map to a normal map?
Open the height map (drop a file onto the page), choose OpenGL or DirectX, set the relief height and save the normal map as PNG, TIFF, EXR or DDS.
Is my image uploaded anywhere?
No. All processing happens locally in your browser. Only anonymous usage statistics (formats and features used, never images or file names) are sent, and you can turn them off.
Which formats are supported?
Input: PNG (8/16-bit), TIFF (8/16/32-bit float), OpenEXR, PSD, RAW/R16/R32, PGM/PFM, JPG, WebP, BMP, GIF, AVIF. Export: PNG, TIFF, OpenEXR, TGA, JPEG, WebP, DDS BC5.
OpenGL or DirectX normal map?
Use the convention of the program or engine that will use the map. Blender, Maya and Unity normally expect OpenGL (Y+); Unreal Engine expects DirectX (Y-); Substance 3D Painter and 3ds Max let you choose per project or material, so check that setting. If the shading looks inverted, switch the convention: it flips the green channel.
