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.If you can't achieve the file size you require with these methods, consider resizing the image to smaller dimensions or cutting the animation duration.Choose the best GIF compression method to drastically reduce GIF file size while preserving quality. The fuzz factor represents how similar colors can be considered as equal. It will give poor results for converted videos or photo slide shows, where most pixels between each frame are significantly different. It may give huge file size reduction in some cases when images have large, static areas, e.g., a recorded screen capture of some program. The results heavily depend on the nature of the image. This option keeps the first frame in the background and makes unchanged parts of the following frames transparent. This will not do anything for most GIFs but can be useful in some special cases. This method will search for identical or very similar consecutive frames, remove them and merge their display duration. Useful for long gifs with a high frame rate.Īnother option is to remove only duplicate frames. The frame drop option can remove every second, third, or fourth frame to reduce frame rate and, therefore, file size. It makes multiple variations of your input image, and you can choose the one with the best size/quality ratio for your needs. This tool shrinks the GIF file size by reducing the number of colors in each frame.Įach GIF frame can use up to 256 unique colors, and by reducing this number, you can achieve a smaller file size. This is the default method and should work for any GIF. You can adjust the compression level with a simple slider to get the best result for your use case. It can reduce the animated GIF file size by 30%-50% at the cost of some dithering/noise. GIF compressor optimizes GIFs using Gifsicle and Lossy GIF encoder, which implements lossy LZW compression.
