Tune CSS easing with a cubic bezier editor

What is cubic-bezier.com?

cubic-bezier.com is a visual cubic bezier editor for crafting the cubic-bezier function used in CSS motion. Instead of guessing numbers, you can drag curve handles, preview motion, and compare easing behavior. Teams use this tool to define a CSS easing curve that matches interaction intent for button states, modals, and complex micro-interactions where animation timing function precision matters.

Core features of the cubic bezier editor

Tools for building accurate motion timing quickly.

1. Interactive cubic bezier editor: Adjust control points visually and generate a usable cubic-bezier function without manual trial and error.
2. Live CSS easing curve preview: Preview how each CSS easing curve changes movement speed over time before applying it in production.
3. Curve comparison workflow: Compare saved curves side by side to evaluate which animation timing function fits each UI interaction.
4. Library import and export: Save and reuse transition easing presets so your team can keep motion behavior consistent across components.
5. Copy-ready output: Copy the generated cubic-bezier function directly into CSS transition and animation declarations.
6. Shareable curve links: Use permalinks to share exact cubic bezier editor settings during design-dev collaboration.

How to use the cubic bezier tool

A quick process for motion tuning.

1. Set a starting curve: Begin with a default cubic-bezier function, then adjust points in the cubic bezier editor.
2. Watch the easing preview: Test each CSS easing curve using different durations to confirm the right animation timing function.
3. Copy and apply: Paste the final cubic-bezier function into your transition easing or keyframe animation CSS.

Tips for better easing curves

Use cubic-bezier values with intent and consistency.

1. Map easing to interaction type: Use gentler transition easing for subtle UI feedback and stronger curves for deliberate entrances.
2. Reuse a small motion set: Standardize a few CSS easing curve presets so your product feels coherent across screens.
3. Validate with real durations: A cubic-bezier function can feel different at 150ms vs 500ms, so test final timing in context.
4. Document the timing tokens: Record each animation timing function in your design system for predictable implementation.

Great for product teams

Where this cubic bezier editor helps most.

1. UI interaction design: Tune hover, press, and focus motion with a precise CSS easing curve.
2. Frontend engineering: Generate and reuse cubic-bezier function values in component styles.
3. Design systems: Define consistent animation timing function tokens across products.
4. Prototype reviews: Compare transition easing options quickly before implementation.
5. Motion QA: Verify that easing behavior matches intended interaction feel.

Benefits of using cubic-bezier.com

Practical advantages in UI motion workflows.

1. Faster tuning: The cubic bezier editor reduces trial-and-error in selecting easing values.
2. More consistent motion: Shared CSS easing curve presets keep interaction behavior aligned.
3. Cleaner handoff: Design and dev can discuss one explicit cubic-bezier function value.
4. Better perceived quality: A refined animation timing function improves interaction polish.
5. Lower rework: Accurate transition easing choices reduce repeated motion adjustments.

Technical details
