Cubic Bezier Generator

How to Use the Free Client-Side Cubic Bezier Generator

Easing curves are hard to describe in words and instantly obvious when you see them move. This generator lets you shape the curve by hand and watch it animate:

1. Drag the two control points on the bezier curve to create your desired easing.
2. Watch the box animate across the screen using your custom easing function.
3. Click Copy to grab the cubic-bezier() CSS value for use in your project.

When to Use Cubic Bezier Generator

Animation feel is what separates a polished product from a mechanical one, and easing is the quiet ingredient behind that feel. Designers creating smooth hover transitions and micro-interactions, developers tuning page entrance and exit animations, and teams building motion into their brand language will use this tool to translate a vague sense of right into a concrete cubic-bezier value.

The interactive canvas makes the curve tangible: two control points define everything, and dragging them reshapes both the curve and the resulting motion. The animation preview shows a box moving under your easing so you judge by eye rather than by math. The velocity graph adds a second lens, showing how speed changes over time and revealing overshoot and easing character that the curve alone hides. Standard presets like ease, linear, ease-in, ease-out, and ease-in-out give you a proven starting point, and exporting is a single copy of the cubic-bezier value ready for a transition or animation property.

Cubic Bezier Generator Tips and Best Practices

1. Start from a preset like ease-in, ease-out, or ease-in-out, then nudge the control points to fine-tune the feel.
2. Prefer ease-out for user-triggered animations such as hovers and button presses, since a fast start and slow end feels natural; ease-in suits auto-played sequences.
3. Keep control point values moderate. Bounces come from y-values outside the 0-1 range, but extremes below -1 or above 2 read as jarring; stay between -0.5 and 1.5.
4. Pair custom curves with enough duration. A complex easing is wasted in 100ms; give micro-interactions 300-500ms and page transitions more.

Why Client-Side Privacy Matters for fine-tuning motion design for unreleased interfaces

Motion direction is a genuine design secret. The easing values, curves, and animation feel under development are part of an unreleased interface, and uploading them to an animation service exposes the way your product will move before it ships.

Everything here runs locally in your browser. The control points you drag and the curves you refine generate CSS on your device alone, so motion experiments and the animation language of unreleased products are never transmitted.
