Image compression

Image compression is a way to make an image take up less space on a computer. It does this by reducing the amount of data needed to store the image. The image will still look the same, but it won't take up as much room on the computer. The way it does this is by looking at all of the pixels in the image and deciding which ones can be removed without making the image look any different.
