A simple, private GIF optimizer
GIF Optimizer is a free online tool for compressing animated GIFs. It processes animations in your browser without uploading your files to a server. Resize images, reduce colors, lower the frame rate, and adjust encoding quality, then compare the previews before downloading. Create smaller GIFs for websites, email, social media, and messaging to improve load times and save bandwidth. Processing stays on your device and works on phones and computers. If the result is no smaller, the tool keeps your original instead.
