What is Rounded Corners?

A free tool that rounds the corners of any picture. Drag one slider to set how round — from a barely-there soften to a fully rounded pill shape — and download the result with transparent corners, ready to drop on any background. Everything runs in your browser; the image is never uploaded.

How do I round the corners of an image?

  1. Upload your image — click Choose an image, drag and drop, or paste from your clipboard.
  2. Set the radius — the slider goes from 0 (square) to 50, where 50 rounds the short side completely into a pill or circle.
  3. Download — PNG by default so the corners stay transparent, at the original resolution, 1200px, or any custom size.

Where rounded corners matter

App icons, website thumbnails, screenshots in documentation, product shots on marketplaces, profile banners, presentation slides — sharp screenshot corners look pasted-on, and a small radius (8–15) instantly makes them feel designed. Larger radii turn photos into cards, and the maximum turns a square image into a circle.

Transparency and formats

The rounded-off corners are transparent, so the image works on any background color. PNG and WEBP keep that transparency; JPEG can't, so JPEG downloads get clean white corners instead. If you need the image on a specific color, layer the PNG over it in any editor — or keep it white with JPEG.

Frequently asked questions

How do I make an image fully rounded, like a circle?

Set the slider to 50. That rounds the corners by half of the image's short side — a square image becomes a perfect circle, a rectangle becomes a pill.

Do the corners stay transparent?

Yes, with PNG (the default) or WEBP. JPEG doesn't support transparency, so those downloads get white corners instead of black artifacts.

What radius should I use?

8–15 for the subtle app-store look on screenshots and thumbnails; 20–35 for card-style photos; 50 for pills and circles. The preview updates live, so just drag until it looks right.

Does the download keep my image's resolution?

Yes — Original is the default and exports at the source resolution. You can also pick 1200px (never upscaled) or type a custom size up to 10000px.

Is the radius the same on all four corners?

Yes, all four corners share one radius, measured as a percentage of the image's shorter side — so the roundness looks consistent whether the image is wide or tall.
