Can I add more than two keyframe steps?

Yes, add as many steps as you need at any percentage.

Does it support transform and opacity only?

Those are the most common properties covered; you can extend the CSS manually after copying.

Can I control iteration count and direction?

Yes, both are configurable, including infinite looping.

Is my data uploaded to a server?

No. This tool runs entirely in your browser using standard web APIs, so your input never leaves your device and nothing is logged or stored on our servers.

Does it work offline and on mobile?

Yes. Once the page has loaded it keeps working without a network connection, and the layout is responsive so it stays usable on phones and tablets.
