Free CSS Cubic Bezier Generator
Create custom easing curves with an interactive visual editor. Generate clean CSS code or Tailwind CSS classes instantly.
About CSS Cubic Bezier Generator
Our Free CSS Cubic Bezier Generator is a powerful online tool that helps you create custom easing functions for CSS animations and transitions. With an interactive curve editor and real-time animation preview, you can design smooth, natural-feeling motion for your web projects.
The generator supports both standard CSS cubic-bezier() output and Tailwind CSS configuration, giving you the flexibility to integrate easing curves into any project. Choose from dozens of preset easing functions or create your own custom curve by adjusting the control points.
Cubic bezier easing functions give you precise control over animation timing, allowing you to create effects like bounce, elastic, snap, and many other motion styles that go beyond the standard ease-in and ease-out functions.

How to Use
Choose a Preset or Start Custom
Select from 12 ready-made easing curves including standard CSS easings (ease, linear, ease-in, ease-out, ease-in-out), Material Design curves, and special effects like bounce, elastic, and snap. Or start from scratch by adjusting the control points.
Edit the Curve
Use the interactive curve editor to drag control points P1 and P2, or use the sliders for precise adjustments. Watch the animation preview in real-time to see how your easing curve affects motion.
Customize Settings
Adjust animation duration, transition delay, and select which CSS properties the easing should apply to. Configure settings for both CSS transitions and animations to match your design requirements.
Copy and Use
Switch between CSS and Tailwind CSS output formats. Click the "Copy Code" button to copy the generated code to your clipboard. Paste it directly into your stylesheet or CSS configuration. The code is clean, well-formatted, and ready for production use.
Cubic Bezier Examples
Standard Ease: cubic-bezier(0.25, 0.1, 0.25, 1.0)
The default CSS ease function. Smooth start and end with a gentle acceleration and deceleration.
Ease Out: cubic-bezier(0.0, 0.0, 0.2, 1.0)
Quick start with smooth deceleration. Perfect for UI elements entering the screen.
Bounce: cubic-bezier(0.68, -0.55, 0.265, 1.55)
Creates a bounce effect by overshooting and returning. Great for playful interactions.
Best Practices for Cubic Bezier Easing
Natural Motion
Real-world objects don't start and stop instantly. Use easing curves that gradually accelerate and decelerate to create natural-feeling animations. Avoid linear transitions for UI elements unless simulating mechanical motion.
Appropriate Duration
Match easing curves with appropriate durations. Quick interactions (100-200ms) benefit from sharper curves, while longer animations (300-500ms) work well with smoother curves. Material Design recommends 200-300ms for most transitions.
Consistency
Use consistent easing curves throughout your application to create a cohesive feel. Define a set of standard easing values in your design system and reuse them across all animations and transitions.
Performance
Prefer animating transform and opacity properties with custom easing curves, as they are GPU-accelerated and provide smooth 60fps animations. Avoid animating layout properties like width, height, or margin with complex curves on low-end devices.
Frequently Asked Questions
Is this CSS Cubic Bezier Generator free to use?
Yes, our CSS Cubic Bezier Generator is completely free with no registration required. You can create unlimited easing curves and copy the generated code for both personal and commercial projects. No watermarks, no limitations.
What is a cubic-bezier easing function?
A cubic-bezier easing function is a mathematical curve defined by four control points (P0, P1, P2, P3) where P0=(0,0) and P3=(1,1) are fixed. The two adjustable points P1 and P2 determine the shape of the curve, controlling how an animation accelerates and decelerates over time.
Can I use the generated easing with Tailwind CSS?
Absolutely! Switch the output format to "Tailwind CSS" to get the configuration code for adding custom easing to your tailwind.config.js file. You can then use your custom easing with Tailwind's transition utilities like transition-[your-easing-name].
What are the valid ranges for control points?
The X values (P1x and P2x) should typically be between 0 and 1, but can extend beyond to create overshooting effects. The Y values (P1y and P2y) can be negative or greater than 1 to create bounce or elastic effects. This generator allows values from -0.5 to 1.5 for full creative control.
What's the difference between transition and animation easing?
CSS transitions use easing for state changes triggered by property changes (like hover), while CSS animations use easing within @keyframes. Both support cubic-bezier() easing, but animations can have different easings for each keyframe. The generated code works for both use cases.
What is Material Design easing?
Material Design defines specific easing curves for different motion patterns. The Standard curve (0.4, 0.0, 0.2, 1.0) is used for most transitions, Decelerate (0.0, 0.0, 0.2, 1.0) for entering elements, and Accelerate (0.4, 0.0, 1.0, 1.0) for exiting elements. These curves create a natural, responsive feel.
Can I create bounce or elastic effects?
Yes! By setting the Y values of control points outside the 0-1 range, you can create overshooting effects like bounce and elastic. The Bounce preset uses cubic-bezier(0.68, -0.55, 0.265, 1.55), and the Elastic preset uses cubic-bezier(0.68, -0.6, 0.32, 1.6) for dramatic overshoot effects.
Do cubic-bezier easing functions work in all browsers?
Yes, cubic-bezier() is part of the CSS Easing Functions Level 1 specification and is supported by all modern browsers including Chrome, Firefox, Safari, Edge, and their mobile versions. Browser support is over 98% globally, making it safe for production use.
