This tutorial talks about the benefits of saving your picture files as PNG instead of Jpeg, or Gif. Jpegs are only good for Photos with “a lot” of colours. PNG are good for saving clipart and photoquality pictures as well. It is a very versatile picture format.

But, gif are still the best for animated gifs.

Benefits

Using Jpeg to save this picture file is a bad idea since it Makes the Picture looks blurry on the Strawberry, and the solid blue areas on the bottum. Look very closely at the strawberryies leaf, and the edge on the blue plate, and you notice a Slightly blurry areas. The photo looks nice, but the clip art of the strawberry looks kind of blurry if you stare long enough.

Gif also offers very bad results since it is limited to only 256 colours, so if you have more then 256 colours in your picture it will look like a comic book with only a few colours. Looks like a comic book which only used 256 colours or less to draw.
