This online utility lets you change the contrast of a GIF animation. You can change the contrast in any rectangular region that you select or in the entire area of the GIF frames. You can increase or decrease the pixel colorfulness by any value, see the result in the preview window in your browser, and download the new GIF file with the new contrast.

This browser-based program increases or decreases the color saturation in GIFs with animated and static frames. If the contrast is increased, then the colors in the frames become more saturated and deep. If the contrast is reduced, then the colors become dull and faint. The contrast of a GIF can be set as a percentage. To increase the animation contrast, use values that are larger than 100% – in the range 101% - 200%. To decrease the animation contrast, use values that are less than 100% – in the range 0% - 99%. All contrast changes are immediately shown in the output preview window and you can also download the changed GIF from right there. In the input preview window, you can adjust the effect zone by dragging the edges of the interactive contrast rectangle with your mouse. Also, the contrast zone can be configured in the options using the exact "x" and "y" coordinates and "width" and "height" dimensions of the frame. Gifabulous!

This example increases the contrast of an animated GIF of ocean waves hitting a cliff. It makes the pixels of all frames more color-saturated and vivid. The new GIF contrast is 150% (which is a 50% increase over the original GIF) and it covers the entire GIF frame area of 380 by 214 pixels. (Source: Pexels.)
This example changes the contrast in a small square region in the center of the animation. This region is 230 by 230 pixels in size and is located at x = 65, y = 20 (the top-left corner position). The pixel chroma value in this region is increased by 60% to 160%, making the iris flower deeply blue. (Source: Pexels.)
In this example, we're decreasing the contrast of a thank you GIF. Originally, the thank you GIF is at 100% and we change its contrast to 75%, making it less colorful. The contrast effect zone is set to the entire area of the animation that has the size of 360×260px. (Source: Pexels.)
