JPEG is designed for compressingeither full-colour or grey-scale digital images of"natural", real-world scenes. It does not work so well onnon-realistic images, such as cartoons or line drawings.

Standards forcompressing those types of images are being worked on by othercommittees, named JBIG and MPEG.
