Control dither in web images

  1. Open an image and choose File > Save For Web.
  2. Choose your optimization settings.
  3. Enter a value in the Dither text box, or click the Dither menu arrow and drag the slider that appears.
  4. The Dither percentage controls the amount of dithering that is applied to the image. A higher dithering percentage creates the appearance of more colors and more detail in an image but can also increase the file size. For optimal compression and display quality, use the lowest percentage of application dither that provides the color detail you require.
