Round Corners FAQ
How do I make a circular image?
Click the 'Circle' preset button or set the radius to a value larger than half the image width. The tool automatically caps the radius to create a perfect circle or the maximum possible rounding.
Why can't I export as JPG?
JPG doesn't support transparency. Since rounded corners create transparent areas, only PNG and WebP formats are available to preserve the transparent background.
