This takes advantage of the format's lossless compression, which favors flat areas of uniform color with well defined edges. The only reason GIFs continue to be so successful is that the format allows animation. The lossiness comes in when a graphics program automatically prefilters or alters the image to compress more efficiently. It might take a second or two but you’ll barely notice. Therefore, the JPEG format, which supports millions of colors, is more commonly used for storing digital photos. JPEGs are more or less a continuation of traditional photography, but GIFs are something new and powerful. For a rich, true color image, GIF may "lose" 99.998% of the colors. PNG, originally created as an improved replacement for GIF, is a popular format used by photographers and graphic designers. Design, code, video editing, business, and much more.
