WebThe image with the 8-bit colour depth only has 256 different colours represented compared to the 24-bit image, which has 16.7 million colours represented. This results in the 8-bit image being poorer quality because humans see more than 256 different colours. The file size of an image depends on the the colour depth of the image.
