Keyframe Animation Generator

The Keyframe Animation Generator is a free online tool that helps you create custom CSS @keyframes animations visually. It is perfect for UI designers and frontend developers who want to add smooth, engaging motion to their web interfaces. Use it to generate complex animation code without writing it from scratch.

How the Keyframe Animation Generator works

  1. 1

    Add Your Content

    Pick one of six ready-made animations (pulse, spin, bounce, fade, slide-in, or shake), then set the duration between 0.2 and 5 seconds and choose an easing curve.

  2. 2

    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.
