Why do these GIFs look better than other converters'?

Two-pass encoding: the first pass builds a 256-color palette tailored to your exact clip, the second renders against it. One-pass converters reuse a generic palette, which is where banding and muddy colors come from.

GIF plays absolutely everywhere. Animated WebP keeps full 24-bit color and is usually far smaller — every modern browser plays it.

How long a clip can I convert?

Up to 15 seconds per run here; GIF sizes grow fast, so shorter and narrower keeps the file sane.
