Three file formats can be used for Web pages: JPEG, GIF, and PNG.
The JPEG format is best used for photographs and other images that contain many different colors, such as detailed artwork.
The GIF format is best used for images that are drawings, simple graphics, navigation buttons, or that contain large areas of solid colors. A GIF can also be animated and can have a transparent background color.
The PNG format was created specifically for Web graphics. It produces high-quality images with small file sizes and is an alternative to the GIF format. Until recently, many browsers couldn't properly display PNG images, but that has changed and more designers are using the PNG format.
