    Preview the animated GIF and save it. Nothing is ever sent to a server.

Frequently asked questions

Are my videos uploaded to a server?+

No. Frames are decoded with the WebCodecs API and encoded to GIF entirely in your browser. Your files never leave your device.

Why is my GIF file large?+

GIF is an old, inefficient format. Keep clips short, lower the frame rate (10–15 fps), and reduce the width to keep file size down.

How long can the clip be?+

There's no hard limit, but GIFs balloon in size quickly. A few seconds at 15 fps and 480px wide is a good target.

Is it free?+

Yes — free, no signup, no watermarks.
