    Questions

    Why does my GIF stop getting faster?

    Browsers show each GIF frame for at least 20 ms (and treat 0 or 10 ms as 100 ms). When frames would be shorter than that, they are merged so the animation still plays at the speed you chose, with fewer frames.

    Is the quality reduced?

    No more than writing any GIF: the frames are the same pictures, stored again with the best 256 colours for the animation.

    Is there a size limit?

    Up to 200 MB per file on a computer (50 MB on a phone). Every frame is unpacked while the GIF is processed, so very long or very large animations need a lot of memory; those limits keep it working on most devices.

    Are my GIFs uploaded anywhere?

    No. Your GIFs are opened and processed on your device, and the results are saved straight back to it. Nothing is uploaded. How to check.

    Is it free? Do I need an account?

    It is free to use and there is nothing to sign up for. There are no watermarks and no daily limits.
