GIF Compressor
Choose a quality preset, color palette size, and resolution scale, then compress your animated GIF and download the result — free, private, and processed entirely in your browser.
About the GIF Compressor
Animated GIFs can quickly balloon in file size, slowing down web pages, blog posts, and chat platforms like Slack or Discord. Our free online GIF Compressor shrinks animated GIFs by reducing the color palette and, optionally, the resolution — while keeping every frame and its original timing intact.
All frame decoding, quantization, and re-encoding happen entirely inside your browser using HTML5 Canvas — your GIF is never uploaded to a server, so processing is fast and your animation stays completely private.
How to Compress a GIF
Step 1
Upload your GIF animation
Upload an animated GIF file to see its frame count and file size.
Step 2
Choose compression parameters
Pick a quality preset, cap the color palette, and optionally scale down the resolution.
Step 3
Compress and download
Click "Compress GIF" and download the optimized file, with every frame and delay preserved.
Frequently Asked Questions
How does color reduction help?
GIFs are indexed-color files limited to 256 colors. Limiting the palette to 128 or 64 colors yields massive size reductions with minor visual differences.
Are my GIFs secure?
Yes, all frame processing and optimization happen locally on your computer inside your web browser.
Will the animation speed stay the same?
Yes, each frame's original delay is read from the source GIF and carried over to the compressed output, so the animation plays back at the same speed.
What does the resolution scale slider do?
It shrinks the GIF's pixel dimensions before re-encoding — useful for animations that are larger than they need to be for where you're embedding them, since fewer pixels means a smaller file.
Does it cost money?
No. The GIF Compressor is 100% free to use, with no registration or account required.
