Dithering in GIF images helps reduce banding in gradients of color, but it also vastly increases the file size. This gallery demonstrates how large the images can get with dithering and no dithering.
For this gallery I started with the same base image, and then saved it in different formats to demonstrate the changes in file size with and without dithering.
Click through the gallery to see the difference in file size between the smallest image and the others.
