# Online Normal Map Generator from Image

URL: https://polyscann.com/studio/image-to-normal

Create an OpenGL normal map online from a photo, color texture, or albedo map. This tool uses a neural model to estimate surface direction from a color image. For grayscale height or displacement input, use the separate Height Map to Normal Map Converter.

## Input and output

- Input: PNG, JPG, or WebP
- Maximum input size: 4096 by 4096 pixels
- Output: OpenGL normal map as 8-bit or 16-bit PNG
- Output size: up to 4096 pixels on the longest edge

Processing runs locally in the browser after the model loads.
