GIF files come in two varieties: static and animated. Static GIFS do not move. Designers use static GIFS to display images such as logos and line art. Animated GIFs, seen on many websites, consist of individual image frames that create the illusion of motion when browsers display them. Several factors determine a GIF's size, including its colour count and the number of image frames if it is an animated GIF. You can make your web pages load faster and save valuable hard drive space by optimising and resizing your GIF files.

Tips and warnings

  • As you review thumbnail choices, note how the image quality goes down as the file size gets smaller. When selecting an image to save, weigh the benefits of achieving a smaller file size against the disadvantages of poorer image quality. You can often remove every other frame from an animated GIF and still maintain an acceptable appearance.The image, however, will move faster because it has fewer frames to display. If you do not want your animated GIF to speed up, do not remove alternate frames.
