How It Works

This free CSS gradient generator builds your gradient entirely inside your browser — nothing is ever sent to a server.

  1. 1. Pick a gradient type

    Choose Linear for a straight directional fade, Radial for a circular or elliptical glow, or Conic for a sweeping colour-wheel effect. Each type gives you its own set of easy controls.

  2. 2. Set your colours

    Click a colour swatch to open the browser's native colour picker, or type a HEX value directly. Drag the position slider to place each stop anywhere from 0% to 100%. Hit Add Stop to build richer, multi-colour gradients — remove any stop with the ×.

  3. 3. Adjust the gradient controls

    Fine-tune the angle for linear gradients, or the centre point and shape for radial ones. The live preview at the top updates instantly as you drag — no buttons to press.

  4. 4. Copy the CSS or download as PNG

    Click Copy CSS to place the complete background: rule on your clipboard — ready to paste into any stylesheet, Tailwind config, or design tool. Or hit Download PNG to save a 1200×630 image generated locally by the browser's Canvas API.

  • Completely free — no account, no watermarks, no limits.

How It Works: Client-Side CSS Generation

The tool builds CSS gradient strings directly in the browser using standard DOM APIs — no external libraries or server calls required.

1

CSS linear-gradient(), radial-gradient(), conic-gradient()

React state holds your colour stops and control values. On every state change, a pure function assembles the correct CSS gradient string, which is applied to the preview div via an inline style attribute — no canvas needed for the preview.

2

Clipboard API for instant copy

Clicking Copy CSS calls the browser's navigator.clipboard.writeText() API. An execCommand('copy') fallback handles older browsers to ensure broad compatibility.

3

Canvas API for PNG export

Downloading a PNG uses an offscreen HTMLCanvasElement (1200×630 px). The tool maps your colour stops to a CanvasGradient (linear or radial), fills the canvas, and calls canvas.toBlob() to create a Blob URL for the download — no server, no upload.

4

Zero dependencies, zero uploads

The component is pure React with no third-party gradient libraries. Colour stops, angles, and positions all live in local component state. Once the page loads, the tool works completely offline — your inputs never leave the browser tab.

Frequently Asked Questions

Does this tool upload anything to a server?

No. The CSS Gradient Generator runs entirely in your browser. No data — colours, settings, or generated images — is ever sent to any server.

What is the difference between linear, radial, and conic gradients?

A linear gradient transitions colours along a straight line at a chosen angle. A radial gradient radiates outward from a centre point in a circle or ellipse. A conic gradient sweeps colours around a centre point like a colour wheel or pie chart.

How do I add more colour stops?

Click the Add Stop button to insert a new colour stop. Pick any colour and drag the slider to place it between 0% and 100%. Remove a stop by clicking the × button — you need at least two stops to form a gradient.

Can I use the generated CSS in any framework?

Yes. The output is standard CSS3 that works in all modern browsers — Chrome, Safari, Firefox, Edge. Paste it into a CSS file, a style attribute, Tailwind's arbitrary value syntax (bg-[linear-gradient(...)]), or any design tool that accepts CSS.

What does the Download PNG button do?

It generates a 1200×630 pixel PNG image of your gradient using the browser's Canvas API and saves it to your device. The image is created locally — nothing is uploaded. This size is ideal for Open Graph (social share) images and design mockups.
