What Are Rounded Corners?
Rounded corners are a design technique where the sharp edges of an image or container are replaced with smoothly curved edges. This creates a softer, more modern and approachable visual aesthetic.
Toolnex AI's rounded corner maker lets you apply adjustable rounded corners to any image with precision control from 0% to 100% radius â all processed directly in your browser for complete privacy.
