Free CSS Gradient Generator Online

A css gradient generator lets you build a multi-color gradient visually — dragging sliders and picking colors — instead of calculating angle values and color-stop percentages by hand and hoping the result looks right. This one builds linear, radial, and conic gradients from any number of hex color stops, shows a live full-size preview that updates as you adjust it, and hands you the exact CSS declaration to copy the moment it looks the way you want.

How This CSS Gradient Generator Works

A large preview box sits at the top of the tool and reflects your current gradient in real time. Below it, three buttons switch between gradient types — Linear, Radial, and Conic — and an angle slider appears for linear and conic gradients (radial gradients in this tool always render as a circle expanding outward from the center, so there's no angle to set for that type). The "Color Stops" section lists each stop with a color picker swatch, an editable hex text field, and a position slider from 0 to 100%; a minimum of two stops is enforced, but there's no fixed ceiling on how many more you can add beyond that with the "Add stop" button. A "Random" button generates a fresh combination — a random stop count, evenly spaced positions, random hex colors, and a random angle — which is a fast way to explore options when you don't have a specific look in mind yet. Fifteen built-in preset swatches sit below the CSS output, each a ready-made two- or three-color combination you can apply with a single click as a starting point to adjust further. The CSS output box shows the exact background declaration for your current gradient, with a copy button to grab it directly.

Why Use a Visual Gradient Generator

Gradients show up constantly in interface design, and building them by eye rather than by formula solves a few recurring problems:

• Building a hero section or page background. A smooth two- or three-color background is a common design choice for landing pages and hero banners, and adjusting stops visually gets you there faster than guessing at percentage values in a stylesheet and reloading the page to check.
• Matching a gradient from a design mockup. When a designer hands off a screenshot with a gradient background, eyeballing the color stops and angle in this tool until the preview matches is quicker than reverse-engineering exact values from a color picker on the image, one pixel at a time.
• Exploring options before committing to one. The Random button is a legitimate way to browse combinations you wouldn't have thought to try manually, then fine-tune whichever one catches your eye rather than starting from a blank two-stop default.
• Building a consistent design-system gradient token. Dialing in a specific brand gradient once and copying the resulting CSS string keeps every component that uses it visually identical instead of each developer eyeballing their own approximation.
• Creating a radial spotlight or hover effect. A radial gradient centered on a card or button, darkening or lightening toward the edges, is a common hover-state or focus effect that's much easier to tune visually than blindly typing percentage guesses into a stylesheet.
• Building conic gradients for wheel-style UI elements. Conic gradients sweep color around a center point rather than across a line, which is the effect you want for color-picker wheels or pie-chart-style visuals — something linear and radial gradients can't produce on their own.
• Generating gradient text or border effects. A common CSS trick renders a gradient as the background of a text element and then clips it to the letter shapes, or applies it as a border image on a card. Dialing in the gradient itself visually here is the first step before applying either technique in your stylesheet.

Reading and Adjusting Color Stops

Each stop's position slider runs from 0 to 100%, representing where along the gradient that color sits, and you can freely reorder how aggressively colors blend by moving stops closer together or spreading them apart. One detail worth knowing: the tool automatically sorts stops by position when it builds the final CSS string, regardless of the order you added them in the list — so if you add a third stop and later drag its position slider to sit before an earlier one, the generated CSS still comes out in the correct left-to-right (or center-outward, for radial and conic types) order, even though the stop still appears lower down in the editor's list. Removing a stop is only available once you have more than two, since a gradient needs at least two colors to mean anything.

Applying one of the fifteen presets is worth a specific note too: the small preview swatches in the presets grid always render themselves as a linear gradient, regardless of which gradient type you currently have selected on the main preview above. Clicking a preset applies its color stops and angle to whatever type you're currently working in — so if you're in Radial or Conic mode when you click a preset, the result uses your currently selected type with that preset's colors, which won't necessarily look identical to the linear swatch you clicked. It's a quick way to load a color combination, just don't expect the exact swatch appearance to carry over if you're not in Linear mode at the time.

Linear, Radial, and Conic Gradients Explained

The three gradient types produce genuinely different visual effects, not just cosmetic variations on the same idea. A linear gradient transitions color in a straight line across the element at whatever angle you set — 0 degrees runs from bottom to top, and the angle slider in this tool sweeps the full 0-to-360-degree range. A radial gradient in this tool always expands outward from the center as a circle rather than an ellipse, with no control over shifting the center point off-axis, so it's best suited to symmetric glow or spotlight effects rather than an off-center highlight. A conic gradient sweeps color around a center point like the hands of a clock, starting from whichever angle you set — that rotational behavior is what makes it useful for color wheels and pie-style visuals that a straight-line or radiating gradient simply can't replicate.

Every color stop in this tool is defined as a hex value, either three or six hex digits, with no support for rgba() or hsl() input and no alpha-channel transparency control. That's a deliberate simplicity tradeoff: hex values are unambiguous and easy to copy from a design tool or brand guideline, but if your gradient needs a translucent fade rather than a solid color-to-color transition, you'll need to add the alpha channel manually to the generated CSS afterward.

Type	Visual Effect	Limitation
Linear	Straight-line transition at a set angle	No curvature or center focus
Radial	Circular expansion from center	Fixed circle shape, no custom center point
Conic	Rotational sweep around a center point	Browser-only — not available via the API

CSS Gradient Generator vs. Hand-Coding and Design Software

Writing gradient CSS by hand gives you precise control and no dependency on an external tool, but calculating clean stop percentages and previewing the result means switching back and forth between your editor and a browser tab anyway — this tool collapses that loop into one place, since the preview and the CSS string update together. A single mistyped hex digit is also easy to miss when writing CSS directly; seeing the swatch next to the text field here catches that kind of error immediately, before it ships to a stylesheet.

Design tools like Figma or Photoshop handle gradients beautifully for mockups, but translating a gradient swatch from a design file into an exact CSS declaration is a manual step those tools don't do for you — you're left reading off approximate color values and guessing at the angle. A generator that outputs the literal CSS string removes that translation step entirely. For teams that need gradient CSS generated programmatically — as part of a design-token build pipeline, for instance — the API endpoint at /docs accepts a gradient type, an angle, and a comma-separated list of two to ten hex colors, and returns the finished gradient string for one credit per call; conic gradients are currently a browser-only feature and aren't exposed through that endpoint.

Privacy and Processing

Every color stop, angle setting, and the resulting CSS stay on your device while you use the free tool — nothing about the gradient you're building is sent to a server as you adjust it. That's a non-issue for most gradients, but it does mean you can freely experiment with an unreleased brand color scheme, an unlaunched product's visual identity, or any other palette you'd rather keep off a third-party server, without that palette passing through anyone else's infrastructure at any point while you're iterating on it.

Common Questions About Building CSS Gradients

Can I use rgba() or hsl() color values instead of hex?

No, both the browser tool and the API endpoint only accept hex colors in three- or six-digit format.

Does the radial gradient support an ellipse shape or an off-center focal point?

No — radial gradients in this tool always render as a circle centered in the middle of the element, with no control over shape or center position.

How many color stops can I add to one gradient?

The browser tool enforces a minimum of two stops but no fixed maximum. The API endpoint accepts between two and ten colors per request.

Is there a way to generate a gradient if I don't have a specific look in mind?

Yes — the Random button generates a fresh combination of stop count, colors, and angle in a single click as a starting point.

Do I need to add color stops in left-to-right order?

No — the tool sorts stops by their position value when it builds the final CSS, so you can add or reorder stops in any sequence and the output still comes out in the correct order.

Can I generate a conic gradient through the API?

Not currently. Conic gradients are only available in the browser tool; the API endpoint supports linear and radial types.

Does this tool support transparent or semi-transparent gradient stops?

No, since only opaque hex colors are supported, there's no alpha-channel transparency control for any stop.

Related Tools

Once you've copied the generated gradient into a stylesheet, the CSS minifier strips it down along with the rest of your CSS before deployment. If you're embedding the gradient directly in a page, the HTML formatter keeps the surrounding markup readable, and the SVG optimizer is worth a look if you're considering an SVG-based gradient background instead of a pure-CSS one. When you're comparing two versions of a gradient's CSS output after tweaking stops or angle, the code diff tool shows exactly what changed between them.
