Dithering is the most common means of reducing the color range of images down to the 256 (or fewer) colors seen in 8-bit GIF images. Dithering is the process of juxtaposing pixels of two colors to create the illusion that a third color is present.
What is the difference between dithered and non dithered GIF?

Do GIFs use dithering?
The GIF format is a compressed, loss-less graphics format that supports only 256 colors. When saving in the GIF format, Photoshop dithering tries to simulate shading, making flat, colored areas appear patchy. Instead, Photoshop has to save the GIF image using the nearest of the 256 colors without using any dithering.
What is a dithered image?
In computer graphics, dithering is an image processing operation used to create the illusion of color depth in images with a limited color palette. Colors not available in the palette are approximated by a diffusion of colored pixels from within the available palette.
