GIF Optimizer
Shrink GIFs in-browser with minimal quality loss.
Runs entirely in your browser. Nothing is uploaded.
How to use
- Drop in an animated GIF.
- Set a scale and choose whether to drop frames.
- Optimize, compare the sizes and download the smaller GIF.
Examples
- Scaling a large GIF to 60 percent often roughly halves the file.
- Keeping one frame in two smooths the size down further for a subtle loop.
- A reduced palette plus a smaller size makes a shareable, lightweight GIF.
Frequently asked questions
Is my GIF uploaded?
No. Frames are decoded and re-encoded entirely in your browser and nothing is uploaded.
Why does the colour look simpler?
GIF supports up to 256 colours. The optimizer fits a shared palette across the frames, which is part of how it shrinks the file.
My browser cannot decode the GIF, why?
In-browser GIF frame decoding needs a current Chrome or Edge. If your browser does not support it, the tool will say so rather than guess.
