Cubic Bezier Generator: Create Custom CSS Easing Curves
The Cubic Bezier Generator lets you design CSS easing curves by dragging two control points or starting from a preset such as ease, ease-in-out, or back. Set a duration to preview the animation live, then copy the cubic-bezier() value or a ready-to-use CSS transition snippet. It makes tuning motion more visual than editing curve values alone.
The Cubic Bezier Generator is a visual editor for creating CSS easing curves. Instead of trying to infer a curve from numbers, you can drag its two control points and see how the motion changes. Choose a standard preset such as ease, ease-in-out, or back, then set a duration and watch a live animation preview.
The curve is represented as a CSS cubic-bezier() value, and the tool can also provide a ready transition snippet. Start with one of the standard easing presets or adjust the control points to shape a custom curve; the duration setting controls the timing used in the preview. Copy whichever result fits your stylesheet or workflow.
A cubic-bezier() value describes easing timing, while a CSS transition declaration can include that easing along with a duration. The generator provides both a curve value and a ready transition snippet, so you can copy the level of CSS detail you need. A visual preview can make it easier to compare motion than editing curve values without seeing the result.
The Cubic Bezier Generator runs entirely in your browser. Your input is processed on your device and is not uploaded, stored, or sent to a server. It works offline once the page has loaded, and the tool is free to use.
This tool can help developers and DevOps engineers prepare easing values for interfaces, tests, fixtures, or seed data. Whether you are learning how CSS easing works or refining an existing interaction, you can adjust a curve, preview it, and copy the result.
Step 1: Choose a standard easing preset such as ease, ease-in-out, or back to get started with a curve.
Step 2: Drag the two control points to adjust the curve visually and shape the motion you want.
Step 3: Set a duration, then watch the live preview to see how the curve animates.
Step 4: Copy the generated cubic-bezier() value or the ready-to-use CSS transition snippet.
Use case: Create a cubic-bezier() value for test cases, fixtures, or seed data when a project needs a concrete easing curve.
Use case: Generate a batch of values when you need several curves at once, rather than inventing each value by hand.
Use case: Use properly random values instead of keyboard guesses when you need randomized curve data.
Use case: Tune a CSS transition visually by adjusting control points and previewing how the motion feels.
Use case: Compare a standard preset such as ease or ease-in-out with a customized curve before copying it into a stylesheet.
Use case: Set a duration and preview an animation to check the timing of an interface interaction.
