The result is large areas of transparency that compresses better (compared to a mix of different colored pixels). If your GIF is an overlaid animation that is repeating pixels that are already being displayed, you can replace those repeating color pixels with transparency. So you can potentially save up to 256 X 3 = 758 bytes per frame by using a single color table.īest for: Use if each frame of your GIF has similar colors. 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. Usually, each frame of a GIF file has it’s own separate color table. However, it may also cause animation artifacts.īest for: Use if your frames have a limited number of colors. 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. GIF files support up to 256 different colors. 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.īest for: Use for high FPS (frames per second) GIFs or Animations with a lot of similar/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. GIF animations are made of multiple image frames. Higher values compress more.īest for: Recommended for most GIFs 2. 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. This slider lets you apply a lossy LZW compression to your GIF. You can apply multiple strategies at once. Our GIF compressor provides 7 GIF compression strategies. While others respond well to lossy or transparency optimizations. Some GIFs benefit vastly by the reduction of colors or the use of a single color palette. So you can compress your GIF files to without worrying about file security and privacy. Plus, all files are protected with 256 bit SSL encryption and deleted after 2 hours. Our GIF compressor is free and works on any web browser. The default settings should reduce GIF file size by up to 60%.
