CSS Clip-path Generator: Looking for an easy way to create CSS clip-path shapes with live preview and clean code export? This CSS Clip-path Generator helps you design polygons, circles, ellipses, and inset shapes visually, then copy ready-to-use CSS for production.

What is a CSS Clip-path Generator?

A CSS clip-path generator is a visual tool that allows you to create non-rectangular shapes to clip elements like images, videos, and divs. It outputs valid CSS code using basic shapes (polygon, circle, ellipse, inset) or references to SVG clipPath for advanced cases.

How does clip-path work?

The CSS clip-path property defines a clipping region that reveals only the part of the element inside the shape. The property accepts basic shapes (like polygon(), circle(), ellipse(), inset()) and also supports path() in modern browsers or url(#clipPathId) to reference SVG clip paths.

How to use the generator

• Choose a shape type: polygon, circle, ellipse, inset, or path (if supported).
  
• Drag points directly on the preview to sculpt your shape.
  
• Toggle percentage/pixel units for responsiveness.
  
• Paste your image or element to preview clipping in real time.
  
• Copy the generated CSS or download as an SVG clipPath if needed.
  

Copy-paste CSS examples

Polygon:

css
.element {
clip-path: polygon(0% 0%, 100% 0%, 100% 80%, 0% 100%);
}

Circle:

css
.element {
clip-path: circle(40% at 50% 50%);
}

Ellipse:

css
.element {
clip-path: ellipse(60% 40% at 50% 50%);
}

Inset with rounded corners:

css
.element {
clip-path: inset(10% 8% 12% 8% round 20px);
}

SVG reference (fallback/advanced):

css
.element {
clip-path: url(#myClip);
}

xml
<svg width=”0″ height=”0″ viewBox=”0 0 1 1″ aria-hidden=”true”>
<clipPath id=”myClip” clipPathUnits=”objectBoundingBox”>
<polygon points=”0,0 1,0 1,0.8 0,1″/>
</clipPath>
</svg>

Why use percentage-based shapes?

• Percentages scale with the element, making shapes responsive across devices without media queries.
  
• Coordinates like polygon(50% 0%, 100% 50%, 50% 100%, 0% 50%) maintain symmetry and adapt to different aspect ratios.
  

Common presets you can generate

• Triangles (up, down, left, right)
  
• Trapezoids and parallelograms
  
• Hexagon, pentagon, and star shapes
  
• Diagonal and slanted sections for hero banners
  
• Organic blobs (using multiple polygon points or SVG paths)
  
• Circular/elliptical reveals for avatars and cards
  

Responsive best practices

• Prefer percentage units for polygon, circle, and ellipse.
  
• Use object-fit: cover on images inside clipped elements to preserve composition.
  
• Combine with container queries or min/max clamp values if shapes distort at extremes.
  

Animating clip-path

• Use keyframes to transition between polygons or animate radius/center for circle/ellipse reveals.
  
• For smooth animations, keep point counts identical between states for polygons.
  
• Consider will-change: clip-path sparingly to hint the browser, and test performance on mobile.
  

Example animation (polygon reveal):

css
.card {
clip-path: polygon(0 0, 100% 0, 100% 0, 0 0);
transition: clip-path 400ms ease;
}
.card:hover {
clip-path: polygon(0 0, 100% 0, 100% 100%, 0 80%);
}

Troubleshooting: Why clip-path may not work

• The element is fully clipped because the coordinates are outside bounds; verify points are within 0%–100%.
  
• Stacking context or transforms may affect the visual result; check parent transforms.
  
• Anti-aliasing can cause jagged edges; try simplifying shapes or slightly adjusting points.
  
• Mobile Safari edge cases: prefer simpler polygons and test with hardware acceleration via transform: translateZ(0) if needed.
  

Clip-path vs. mask-image

• clip-path cuts hard edges and does not support gradients; great for geometric shapes.
  
• mask-image supports grayscale and gradients for soft fades and complex reveals.
  
• Use clip-path for performance and simplicity, mask-image for advanced visual effects.
  

Accessibility and UX considerations

• Clipping doesn’t change the DOM structure; screen readers still access full content. Ensure visual clipping doesn’t hide essential focus indicators.
  
• Maintain visible focus rings; avoid clipping the area where users navigate.
  
• Provide graceful fallbacks for older browsers (e.g., squared shapes or SVG references).
  

Performance notes

• Simple shapes (circle, ellipse, inset) typically render faster than complex multi-point polygons.
  
• Animating fewer points is smoother and less GPU-intensive.
  
• Test large images and layered effects on low-end devices to avoid jank.
  

Developer workflow tips

• Save shape tokens as CSS variables for reuse:

css
:root { –clip-hero: polygon(0 0, 100% 0, 100% 85%, 0 100%); }
.hero { clip-path: var(–clip-hero); }

• Mirror shapes using transforms instead of duplicating coordinates.
  
• Keep a library of presets (triangles, slants, blobs) for rapid prototyping.
