Round Image Corners

Rounded corners soften screenshots, avatars and product shots without opening an editor. Drop one image or a whole batch, drag the radius slider and watch the preview update live — the radius goes all the way to a full circle, capped at half of the shorter side.

Choose whether the clipped corners stay transparent (PNG) or get filled with a solid color, which is also what JPG output needs since it has no alpha channel. Every file is processed on your device and downloaded individually.

Frequently asked questions

Can the corners be transparent instead of white?

Yes — pick PNG output and the Transparent option, and the corners stay see-through. JPG has no alpha channel, so it always fills the corners with the solid color you chose.

The same radius looks different on each image — why?

The slider sets the radius in pixels, and every file is rounded with exactly that radius, clamped to half of its own shorter side. For a uniform look across differently sized images, match their sizes first (for example with the image resizer).

Does rounding reduce image quality?

Only the corners are touched — the pixels inside stay untouched. PNG output is lossless, while JPG is re-encoded at high quality, which can shift the file size a little either way.
