What is the Border Radius Generator?

It’s a free online tool that helps you visually design rounded corners—control each corner's radius individually or uniformly—and instantly generates the CSS code.

How does the radius control work?

You can drag points or use sliders to adjust each corner. Some tools also let you merge corner controls to set uniform values across all corners.

Can I preview the rounded corners in real time?

Yes — the tool updates a live preview immediately as you change settings, making it easy to visualize the effect.

What kind of CSS does the tool generate?

It produces valid CSS using the `border-radius` property—supporting one, two, three, or four values, and optionally slash-separated syntax for elliptical corners.

Is the CSS code browser-compatible?

Yes — the `border-radius` property is well-supported in all modern browsers, so your designs will render consistently across platforms.

FreeUICode’s Border Radius Generator Is the Simplest Way to Perfect Your CSS Designs

In today’s web development world, clean and responsive design isn’t just a trend—it’s an expectation. And when it comes to achieving smooth, modern UI elements, rounded corners play a crucial role. That’s where the FreeUICode Border Radius Generator steps in—offering a lightning-fast, intuitive way to create perfectly curved elements using CSS.

Whether you’re a beginner or a professional developer, this tool helps you build pixel-perfect corners without writing code manually.

Why Use a Border Radius Generator?

The CSS border-radius property allows developers to round the corners of any element—boxes, buttons, cards, or images. While the syntax is fairly straightforward, it can become tricky when customizing individual corners or experimenting with organic, asymmetrical shapes.

This is where a border radius generator tool becomes essential. With FreeUICode’s tool, you can:

Preview changes in real-time.
Adjust each corner individually or all at once.
Copy clean CSS code with one click.
Instantly implement rounded borders in any frontend project.

Real-World Use Cases for Border Radius in Modern Web Design

Rounded corners aren’t just for buttons—they’re a subtle but powerful way to enhance overall design flow. Today’s websites, especially mobile-first layouts, rely on soft edges to create a sense of depth, approachability, and modernity.

Here are some common applications of border radius:

Call-to-Action Buttons: A smooth, rounded button is more clickable and visually inviting than sharp edges.
User Profile Cards: Border-radius helps soften image containers and profile cards, making social platforms and directories look cleaner.
Chat Interfaces: Bubbles for messages often use asymmetrical border-radius to create the classic chat design.
Image Thumbnails: Rounded thumbnails add elegance and remove the harshness of square images.
Pricing Tables and Feature Blocks: Rounded containers can visually separate different pricing tiers or feature sets without relying on harsh dividers.

You can combine border-radius with shadows, gradients, or hover animations to create even more visually engaging elements. Tools like FreeUICode’s Border Radius Generator make it easy to test different styles before committing them to your production environment.
