    Format Your Data

    The tool calculates the exact @keyframes rule and the corresponding animation shorthand properties. It updates a live preview so you can watch the animation play in real time.

  3. 3

    Get Your Results

    Copy the generated CSS code from the output panel. Paste it directly into your stylesheet to apply the smooth animation to your web elements.
