JPEG (Joint Photographic Experts Group) file
format is the superior format for photographic or
continuous-tone images, because JPEG files can contain
millions of colors. As the quality of a JPEG file increases,
so does the file size and the file download time. You can
often strike a good balance between the quality of the image
and the file size by compressing a JPEG file.
PNG (Portable Network Group) file format is a patent-free
replacement for GIFs that includes support for
indexed-color, grayscale, and true-color images, and alpha
channel support for transparency. PNG is the native file
format of Macromedia Fireworks MX. |
