What Is the Rounded Corners Tool?

The Rounded Corners tool adds smooth rounded corners to your image and exports a transparent-background PNG, ideal for avatars, icons, and design assets.

The corner radius is fully adjustable, from slightly rounded to a complete circle.

How to Add Rounded Corners to an Image

Follow these steps:

  • Drop or upload an image.
  • Drag the slider to adjust the corner radius.
  • Click Apply Rounded Corners and preview the result.
  • Download the PNG with a transparent background.

Tips

  • For avatars, a radius around 25% of the image size looks best.
  • Icons commonly use a radius-to-size ratio of about 22%.
  • When the radius exceeds half the image size, the image becomes a circle.
