When optimizing GIF images, it is useful to keep in mind that GIF compression works by condensing bands of repetitive pixel colors. Many optimization strategies work by creating more areas of solid color for the compression scheme to sink its teeth into.
The general methods for keeping GIF file sizes in check are:
• Reducing the number of colors (the bit-depth) of the image
• Reducing dithering in the image
• Applying a “lossy” filter
• Designing with flat colors
Reducing the number of colors
The most effective way to reduce the size of a GIF file, and therefore the first stop in your optimization journey, is to reduce the number of colors in the image.
