Creating images with transparent backgrounds

GIF images with transparent backgrounds, such as buttons and logos, are commonly used on Web pages with colored or patterned backgrounds.

If you place an image with an opaque background onto a Web page, the image background color appears as a rectangle on the page. By making an image background transparent, the image background blends in with the page. Transparent image backgrounds also let you change the color or pattern of a Web page background without having to change the backgrounds of the images to match.

The background color must be a single, solid color that is not used elsewhere in the image. You can also make an editable area or a protected area transparent. For information about defining these areas, see “Working with masks.”

For information about the GIF file format, see “Choosing a Web-compatible file format.”
