Animated GIFs are fun but they get heavy fast, and an oversized GIF can be too big to send in chat or slow a page to a crawl. Resizing and compressing one keeps the animation while cutting the file size — and you can do it free securely, with nothing is stored.
Pick the animated GIF you want to make smaller.
Scale the GIF down — smaller dimensions mean a smaller file.
Lower the frame rate and colour count to shrink the file further.
Export the optimised GIF, ready to share.
What actually shrinks a GIF
GIF size is driven by three things: dimensions, frame rate and colour palette. Halving the width can cut the file to a quarter. Dropping from 20 to 10–15 FPS removes frames most people won’t miss. And limiting the palette to 64–128 colours often looks fine while saving a lot. Combine all three for the biggest reduction.
Keeping it looking good
- For chat and email, 320–480px wide is usually plenty.
- 15 FPS is a good balance of smooth and small.
- Flat, simple animations survive palette reduction best.
Tip: Need a GIF from a video instead of resizing one? Use the Video to GIF tool, which lets you set the width and frame rate as you create it.
