IMAGE CONVERSION TOOL
Turn a photo, painted texture, or material reference into a usable tangent-space normal map without uploading the source file.
Free local converter
No account is required. Upload a source, adjust the controls, and export the map when the preview looks right.
Generate Normal, Height, AO, and Displacement maps locally while you tune the surface response for your target renderer.

How to use this converter
Keep the important decisions visible: source quality, surface strength, renderer direction, and the final lit result.
Drop a PNG, JPG, or WebP into the local converter, or start with a procedural sample texture.
Adjust Strength, Blur, and Contrast until edges and fine details read naturally under light.
Apply Blender, Unity, or Unreal to set the expected OpenGL or DirectX Y direction.
Switch between Normal, Height, AO, and Displacement, then export the active output as a PNG.
Start with an image that contains visible surface detail. The converter reads luminance changes as an approximation of height.
Preview the generated maps before you download a PNG. Use the 3D surface preview to catch weak detail or an inverted green channel.
A generated normal map changes lighting response; it does not recover true geometry, remove baked shadows, or correct a perspective-heavy photograph. Validate the exported map in the target material and at the scale where it will be rendered.
FAQ
Use these answers to choose a better source, engine direction, and export workflow for your material.
Most images can produce a starting point, but the result is strongest when brightness changes correspond to real surface detail. Portraits, smooth gradients, and photographs with baked shadows may need manual cleanup.
No. The free converter decodes and processes the image in the current browser tab. The normal map generation step does not send the source file to a conversion server.
Lower Strength first, then add a small amount of Blur and reduce Contrast. A clean input with even lighting usually improves the result more than aggressive sharpening.
The tool exports a PNG, which is a practical lossless interchange format for most Blender, Unity, and Unreal workflows. Confirm the target engine import and compression settings before shipping.
The green channel direction may not match the renderer. Select the engine preset that matches your workflow or toggle Invert Y before exporting again.
No. A normal map changes how a surface responds to lighting. It does not add polygons, recover hidden depth, or fix perspective and baked lighting in the source image.
