Best for: Use if each frame of your GIF has similar colors.So you can potentially save up to 256 X 3 = 758 bytes per frame by using a single color table. As we mentioned, a color table can have up to 256 colors, and each color is 3 bytes. This option will instead force the GIF to use a single global color table.

Use a single color table: Usually, each frame of a GIF file has its own separate color table.Best for: Use if your frames have a limited number of colors.However, it may also cause animation artifacts. Naturally, this will produce better-looking GIFs at the expense of bigger file size. Reduce colors + dither: Using the dither option will force the algorithm to approximate the missing colors using combinations of colors.You can choose to reduce colors up to just 2 colors. Reducing the number of colors in colormap can reduce GIF file size. Reduce colors: GIF files support up to 256 different colors.Best for: Use for high FPS (frames per second) GIFs or Animations with a lot of similar/duplicate frames.We also provide a Fuzz Factor, which is a measure of “similarity.” The larger the ‘fuzz factor’ more ‘similar’ frames will match and be dropped. Remove duplicate frames: Removing similar or duplicate frames will help to optimize your GIF file size.This is useful for GIFs created out of high-FPS videos. For example, dropping every 2nd frame would result in 50% fewer frames. This feature allows you to drop every 2nd, 3rd, 4th, or 5th frame of your GIF. Obviously, dropping frames will reduce gif size. Depending on the animation, you might be able to drop frames without much noticeable change to the animation itself. Drop nth frame: GIF animations are made of multiple image frames.We recommend applying a 75% lossy compression level and adjusting further if needed. However, often, the quality loss is undetectable. It can reduce GIF file size by up to 60% at the expense of some noise and dithering. Compression level: This slider lets you apply a lossy LZW compression to your GIF.Choose the best GIF compression method to drastically reduce GIF file size while preserving quality.
