Optimizing a GIF Document
TheGIFfileformatisusedprimarilyforimagesthatcontainsolidcolorswithsharpedges,
such as clip art, text, line art, and logos. Since the Internet can generally be slow to nav-
igate, using the GIF format for images significantly reduces their file size, and will create
fast-loading graphics. The GIF format supports 8-bit color, and creates a document with
a maximum of 256 colors (the fewer colors, the smaller the file size). The GIF format
has been around long enough for it to be considered a “native” Internet format. A
native
format
is one that does not require a specific plug-in for the browser to display the file.
