WebThe JPEG compression algorithm operates at its best on photographs and paintings of realistic scenes with smooth variations of tone and color. For web usage, where reducing the amount of data used for an image is important for responsive presentation, JPEG's compression benefits make JPEG popular. WebAn image can be compressed by reducing its colour depth. This reduces the range of colours that the image contains. In practice, this results in an averaging of shades of colours.
