How to round image corners (four steps, maybe ten seconds)
Not complicated. Here's the whole thing.
Drop your image
Drag any JPG, PNG or WebP onto the tool. Or click to browse your files.
Set the radius
Use the slider to control how round the corners are. 0% is sharp, 50% on a square image gives you a circle.
Pick a background
Choose transparent (great for logos and overlays) or pick a solid color to fill the space outside the corners.
Download your PNG
Hit download. You get a full-resolution PNG with your rounded corners baked in.
Where rounded corners actually show up
App screenshots. Blog thumbnails. Profile pictures that are not quite circular but not square either. UI mockups, especially when you are showing off a design and want the screenshot to look polished rather than raw. Browser framed screenshots where the image needs to fit inside a rounded container.
If you have ever pasted a screenshot into a slide deck and thought “that looks harsh,” rounded corners are probably what you needed. It is a small change that makes a surprisingly large visual difference. Most modern UI design uses rounded corners everywhere, so images with sharp corners can feel out of place.
50% radius: the circle trick
On a square image, setting the radius to 50% creates a perfect circle. This is the same result as the circle crop tool, but with a different level of control. The circle crop tool gives you a fixed circle, while this tool lets you dial in any rounding amount from a subtle curve to a full circle.
On a rectangular image, 50% turns the shape into a pill or stadium shape. That can look interesting for buttons and labels, but it is probably not what you want for most photos.
Transparent vs colored background: which to use
Transparent works when you plan to place the image on top of something else, like a website background or a slide. The rounded corners will blend cleanly with whatever is behind them.
A solid color background (typically white or the same color as your page background) works when you need a JPG-compatible result or when the image will be displayed on a known background color. White is the safe default for most situations.
Thinking in percentages, not pixels
The radius here is a percentage of the image's shorter side, which is deliberate. A 20 pixel corner looks generous on a 300 pixel thumbnail and barely visible on a 3000 pixel photo. A percentage keeps the look the same whatever the image size, so the same setting works on a thumbnail and on a full size version of it.
App icons do not need rounding
If you are preparing an app icon, submit it square. iOS and Android apply their own corner shapes to icons automatically, and Apple's is a smooth curve that a simple radius does not match exactly. Rounding it yourself can leave visible corners peeking out, or rounding stacked on rounding.
GIFs and animation
GIF files are accepted, and the first frame is rounded and saved as a PNG. Animation is not kept, because the result is a single still image.
