Rounded corners are a small touch that makes an image look modern and intentional — the difference between a raw screenshot and a polished card. Avatars, app icons, thumbnails and UI mockups nearly all use them. You can round the corners of an image for free in your browser, with no upload or watermark.
Why round the corners
- A softer, friendlier look — rounded corners feel less harsh than sharp ones.
- Match a design system — most apps and sites use rounded cards and avatars.
- Profile pictures — many platforms display avatars with rounded or circular masks.
- Privacy — the image is processed on your device, never uploaded.
Step-by-step
- Open the Round Corners tool.
- Drop in your image.
- Set the corner radius — a little for a subtle curve, more for a pill or circle.
- Download the rounded image as a PNG.
Why the result is a PNG
Rounding a corner means the area outside the curve has to become transparent — and only formats that support transparency can store that. JPG can't, so it would fill the corners with a solid colour and undo the effect. That's why the tool exports a PNG, which keeps the corners see-through so the image sits cleanly on any background. If you need an exact size first, crop or resize with the Crop and Resize tools, then round.
FAQ
Can I make the image a circle? Yes — set the radius to the maximum on a square image for a full circle.
Why is it a PNG, not a JPG? The rounded corners need transparency, which JPG doesn't support.
