Tune CSS easing with a cubic bezier editor
Use a cubic bezier editor to preview and compare CSS easing curves, then copy cubic-bezier values for smooth transitions and animation timing.
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.
Adjust control points visually and generate a usable cubic-bezier function without manual trial and error.
Preview how each CSS easing curve changes movement speed over time before applying it in production.
Compare saved curves side by side to evaluate which animation timing function fits each UI interaction.
Save and reuse transition easing presets so your team can keep motion behavior consistent across components.
Copy the generated cubic-bezier function directly into CSS transition and animation declarations.
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.
Begin with a default cubic-bezier function, then adjust points in the cubic bezier editor.
Test each CSS easing curve using different durations to confirm the right animation timing function.
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.
Use gentler transition easing for subtle UI feedback and stronger curves for deliberate entrances.
Standardize a few CSS easing curve presets so your product feels coherent across screens.
A cubic-bezier function can feel different at 150ms vs 500ms, so test final timing in context.
Record each animation timing function in your design system for predictable implementation.
