GIF

GIF is the standard file format used for Web graphics. It's an 8-bit format, which means a GIF image can contain a maximum of 256 colors. Most browser palettes are also 8-bit, which means they too can display a maximum of 256 colors—not the thousands or millions of colors that are needed to make images look pleasing to the eye. Colors that a browser palette lacks are simulated by dithering, a display technique that intermixes color pixels to simulate other colors. Since color substitutions are more noticeable in solid-color areas than in continuous-tone areas, GIF is a good format choice for images that contain solid-color areas or shapes with well-defined edges, such as type . GIF can save fully transparent pixels (one level of transparency).

GIF is a suitable export format for this image, which contains only solid-color shapes.
