CSS Clip-Path Generator: Create Custom Shapes Visually

The CSS clip-path property is one of the most powerful and underused tools in modern web design. It lets you clip an element to a specific region, turning ordinary rectangles into circles, polygons, stars, and completely custom shapes — all without touching an image editor or exporting a single SVG. Whether you're masking a hero image, building a geometric avatar, or crafting decorative badges, clip-path gives you crisp, scalable results that adapt to any screen.

Writing clip-path values by hand, however, can be tedious. Getting the coordinates of a five-point star exactly right, or remembering whether circle() takes a radius or a percentage first, slows down the creative process. That's where the CSS Clip-Path Generator comes in — an interactive visual editor that lets you design shapes in real time and export production-ready CSS with a single click.

In this guide, we'll explore why clip-path belongs in every front-end toolkit, walk through the features of the generator, deep-dive into each shape function, and look at practical use cases you can drop straight into your projects. Head over to the CSS Clip-Path Generator to follow along as you read.

Why Use CSS Clip-Path?

• Visual editing — Adjust shapes with intuitive sliders and inputs instead of hand-calculating coordinate percentages. The preview updates instantly so you can experiment freely.
• All shape functions — Native support for circle(), ellipse(), polygon(), and inset() means you can build any shape the CSS spec allows, not just a few hand-picked presets.
• One-click code export — Copy the final clip-path declaration — complete with the -webkit-clip-path vendor prefix — straight into your stylesheet. No manual typing, no missing prefixes.
• Preset shapes — Start from a Diamond, Hexagon, Star, or Triangle and customize from there, saving time on the shapes you reach for most.
• Built-in validation — Polygon coordinates are validated as proper percentage pairs, so you never ship a malformed clip-path that silently breaks your layout.
• Accessibility aware — ARIA labels and aria-live announcements keep the editor usable with assistive technologies, and the interface is fully keyboard navigable.

Key Features

• Every control is shape-specific, so the editor only shows inputs relevant to the function you've selected — no clutter, no confusion.
• The generated code block is copy-ready: paste it into your CSS and you're done. Both the standard and -webkit- prefixed declarations are included.
• Polygon input is validated in real time, flagging malformed coordinate pairs before they can produce a broken clip region.

How to Use the CSS Clip-Path Generator

1. Open the tool at /en/tools/css-clippath-generator. You'll see the preview canvas on one side and the controls panel on the other.
2. Choose a shape function — circle, ellipse, polygon, or inset — from the shape selector. Alternatively, click a preset (Diamond, Hexagon, Star, Triangle) to start from a ready-made design.
3. Adjust the controls for your chosen shape. For a circle, drag the radius and position sliders; for an inset, set each side and the round value; for a polygon, edit the coordinate points directly.
4. Watch the preview update in real time as you make changes. Use this instant feedback to fine-tune the shape until it's exactly what you want.
5. Copy the generated CSS with the one-click copy button. The output includes the vendor-prefixed declaration, so paste it straight into your stylesheet and apply it to any element.

Understanding clip-path Functions

circle()

The circle() function clips an element into a perfect circle. It takes a radius followed by the keyword at and a position.

.element {
  clip-path: circle(50% at 50% 50%);
}

The first value is the radius (50% fills the element), and the coordinates after at set the center point. Move the center off to one side to create a partial-arc effect.

ellipse()

The ellipse() function works like circle() but accepts two radii — horizontal and vertical — letting you create oval shapes.

.element {
  clip-path: ellipse(50% 35% at 50% 50%);
}

The first two values are the X and Y radii, followed by the center position. This is ideal for organic, pill-like, or vertically stretched shapes.

polygon()

The polygon() function is the most flexible. Each pair of coordinates defines a vertex, and you can chain together as many as you need.

.element {
  /* Diamond */
  clip-path: polygon(50% 0%, 100% 50%, 50% 100%, 0% 50%);
}

.element {
  /* Five-point star */
  clip-path: polygon(
    50% 0%,
    61% 35%,
    98% 35%,
    68% 57%,
    79% 91%,
    50% 70%,
    21% 91%,
    32% 57%,
    2% 35%,
    39% 35%
  );
}

Coordinates are expressed as percentages relative to the element's bounding box. The generator validates these pairs for you, so they're always well-formed.

inset()

The inset() function clips the element by specifying how far to inset from each of the four edges. An optional round keyword adds rounded corners.

.element {
  clip-path: inset(10% 10% 10% 10% round 10px);
}

The four values correspond to top, right, bottom, and left insets (just like margin). The round value works like border-radius, letting you create rounded, clipped rectangles.

Practical Use Cases

Image Masking

Turn a rectangular photo into a circle or hexagon for avatars, thumbnails, or decorative galleries.

.avatar {
  clip-path: circle(50% at 50% 50%);
  -webkit-clip-path: circle(50% at 50% 50%);
}

.gallery-item {
  clip-path: polygon(50% 0%, 100% 25%, 100% 75%, 50% 100%, 0% 75%, 0% 25%);
  -webkit-clip-path: polygon(50% 0%, 100% 25%, 100% 75%, 50% 100%, 0% 75%, 0% 25%);
}

Creative Hero Sections

Add geometric flair to hero banners by clipping background images into angled or polygonal shapes — no PNG masks required.

.hero {
  clip-path: polygon(0% 0%, 100% 0%, 100% 85%, 0% 100%);
  -webkit-clip-path: polygon(0% 0%, 100% 0%, 100% 85%, 0% 100%);
}

Decorative Cards and Badges

Use inset() with a round value to create distinctive clipped cards, or layer polygons for starburst badges and sale tags.

.badge {
  clip-path: polygon(
    50% 0%,
    61% 35%,
    98% 35%,
    68% 57%,
    79% 91%,
    50% 70%,
    21% 91%,
    32% 57%,
    2% 35%,
    39% 35%
  );
  -webkit-clip-path: polygon(
    50% 0%,
    61% 35%,
    98% 35%,
    68% 57%,
    79% 91%,
    50% 70%,
    21% 91%,
    32% 57%,
    2% 35%,
    39% 35%
  );
}

Geometric Avatars and Placeholders

Create consistent, branded placeholders using ellipse() or inset() shapes that scale cleanly at any size.

.placeholder {
  clip-path: ellipse(50% 40% at 50% 50%);
  -webkit-clip-path: ellipse(50% 40% at 50% 50%);
}

Best Practices

• Always include the -webkit- prefix. Older versions of Safari require -webkit-clip-path, and the generator outputs both declarations automatically. Keep both to maximize compatibility.
• Provide a sensible fallback. Elements with clip-path will appear un-clipped in unsupported browsers, so make sure the underlying content still looks acceptable as a rectangle. Use @supports to apply progressive enhancements.
• Use @supports for graceful enhancement. Wrap advanced clips in @supports (clip-path: polygon(0 0)) { ... } so legacy browsers get a clean fallback instead of a broken layout.
• Remember accessibility. Clipping is purely visual — it doesn't hide content from screen readers. If you're using clip-path to visually hide something, pair it with appropriate visually-hidden techniques so you don't expose stale content to assistive tech.
• Animate carefully. clip-path can be animated for reveal effects, but animating complex polygons can be expensive. Prefer animating simple values (like a circle radius or inset percentages) and test performance on lower-end devices.
• Keep coordinates proportional. Use percentage-based coordinates rather than fixed units so your shapes scale with the element. This keeps masks responsive across viewport sizes.
