JPEG files are perfect for color images containing millions of color combinations such as a photograph. GIF work perfect for limited color files, like simple graphics or logos that might also need transparency for blending into any background on a site design.

Multiple versions of the PNG file formats allow simple to complex styles without sacrificing loss in compression like JPEG formats.
