Why would you dither an image?
Dithering in image processing is a technique used to simulate colors or shading. The basic concept behind dithering is adding noise, or additional pixels, to a digital file. In graphics, dithering adds random patterns of pixels to improve the image quality while avoiding banding.

How does dithering affect the size of an 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.
Is there a way to dither an image in Photoshop?
Images with primarily solid colors may work well without dithering. Conversely, images with continuous-tone color (especially color gradients) may require dithering to prevent color banding. Open an image and choose File > Save For Web. Choose your optimization settings.
