Creating favicon.ico


You want to create a favicon.ico from Unix.



  1. Open your image with GIMP
  2. If your image is not a square then resize the canvas with GIMP
  3. Scale the image to 16×16 pixel (Image, Scale image)
  4. Save as favicon.pnm or favicon.ppm with raw encoding
  5. Close GIMP



Then to convert favicon.pnm or favicon.ppm using the command line utility ppmtowinicon:
