GIF saves the image to a smaller file size than a BMP. This is the format most
commonly used for Web pages and is most appropriate for graphics and illustrations
that are relatively small and do not contain a lot of tonal nuances. When saving an
image in this format, you can choose how many colors you want the engine to
recognize. A lower number of colors generally results in smaller file size, but in some
cases might compromise the quality of the image. You can also set the background to
be transparent, so that when you place the image on a Web page, the background of the
Web page will appear as the backdrop for the image.
•
JPEG saves the image to a small file size and also offers very good compression for
True Color images. This format is commonly used for Web pages. One minor
disadvantage of the JPEG format is that some data are lost when compressing the file.
In most cases, the changes are barely noticeable to the naked eye and you can control
how much is actually changed.

Colors Specifies the number of colors
to create in the global palette of each
frame, based on the colors in that
image. A lower number of colors helps
to reduce file size, but sometimes at the
cost of image quality.
•
Dither Select to simulate True Color by
mixing the existing colors in the palette
for the optimize image.
•
Interlace Select to create an interlaced
GIF image when you save the optimized
image. This increases file size but
displays better quality.
