Like GIFs and JPEGs, PNG images are ideal for web use. Like GIFs, the PNG is great for displaying small images with few colors, like logos and icons. Also, PNGs sport a few advantages over GIF images. Most notably, they support alpha transparency.

What is alpha-transparency? GIF files are only capable of displaying a pixel as either completely transparent or completely opaque: this is known as binary transparency. When an image contains alpha layers, however, parts of an image can be partially transparent."
