Animated GIFs get big quickly, and plenty of sites and email clients reject large files. The good news: you can usually cut a GIF's size by more than half with no obvious loss.
The three levers
Every GIF's size comes down to three things:
- Dimensions — a 480px-wide GIF is a fraction of a 1080px one. Resize it first.
- Frame rate — dropping from 30 fps to 12 fps roughly halves the frames.
- Colour palette — fewer colours means a smaller file. This is what Compress GIF tunes for you.
How to compress
- Open Compress GIF.
- Drop in your GIF.
- Pick a compression level — Medium is the recommended balance.
- Download the smaller GIF.
It runs in your browser, so even a big GIF is processed on your device without uploading.
When to give up on GIF
If you still can't get it small enough, the format is the problem, not the settings. Convert it to MP4 — it'll be dramatically smaller while looking better. See why GIFs are so large.
