How do I add rounded corners to an image?

Upload your image, adjust the corner radius using the slider (percentage of the image size), then click Apply. The output is a PNG with a transparent background in the corners.

Why is the output always PNG?

Rounded corners require a transparent background in the corner areas. Only PNG and WebP support transparency, so the output is PNG to preserve the transparency.

Can I round corners on multiple images at once?

Yes. Upload multiple images and the same radius will be applied to all. Download individually or as a ZIP.

Is the rounded corners tool free?

Yes, completely free. No account required, no watermarks.

Are my images private?

Yes. All processing happens in your browser using the Canvas API. Your images never leave your device.
