Best tools to compress your GIF images

GIF images can get quite large. Fortunately there are many free tools online to compress your GIF images on the web and create an optimal image which supports animation for sharing. Many of these services have limits to the maximum file size. Compressing a GIF image will not usually reduce image quality. If you do notice a change in image quality, try toggling the number of colors in compressed file format. By reducing the size of your GIF image and if you are planning to save for web, you are also helping to decrease page load times, reduce server resources, save power and so on.

Looking to share to GIF images on social media, be sure to compress the file enough to allow it to be uploaded. For example Twitter supports GIF uploads of just 15MB, anything other that will need to be compressed into a smaller file size.

Compress your GIF online

There is no need to download any software to compress a GIF image for the purpose of size reduction. These online image resizer apps will allow you to reduce the file size of a GIF. We found Kraken to be the most effective at compression for file support, it does also have the lowest limit and only allows files under 1000 bytes to be uploaded without signing up. They are however limited with what file size you can upload and they all allow the GIF image format.

Software to optimize a GIF on your computer

If you have a lot of images to compress or need a larger image optimized, then software that you download and use on your computer may be a more suitable solution.

Using software like Adobe Photoshop on your computer to reduce GIF file size may also include other features where you can create a GIF animation from a video file or resize GIF image format file. If you have an animated GIF then it may be a good idea to remove any duplicate frames before compressing to help reduce the size. 

Lossy GIF compression

GIF compressor optimizes GIFs using gifsicle and Lossy GIF encoder, which implements lossy LZW compression. This compression level can reduce animated GIF file size by 30% to 50% with lossy compression at a cost of some dithering/noise, without reducing the number of frames in part of the image. Reducing the amount of color used in the GIF will also further reduce the size, you can use less than 256 colors for most GIFs. 

Further reduce size of the file by re-sizing

If your image is still too large after compression, it is worth trying to resize the image if possible. The EZgif website has a great tool for resizing animated GIFs. We tested a large file in GIF format of about 70MB and got it down to less than 20MB with some minor resizing and compression. You may also be able to optimize transparency and further reduce the size of your online GIF file.
