Crop an image to rounded corners or a circle and save a transparent PNG.
Clip an image to either a rounded rectangle or a centered circle and save the transparent result as PNG.
Circle mode does not reposition the subject. If a face sits near an edge, crop or reposition the photo first or the centered circle can cut the subject off.
The tool takes a centered square from the original image and then applies the circular mask. It does not squeeze the full rectangle into a circle.
Only the corner mask changes. Width and height remain the same as the source rather than being cropped to a new aspect ratio.
The regions outside the rounded or circular shape are transparent, so the result is exported as PNG rather than JPEG.
The percentage is converted to a pixel radius using the shorter image dimension, giving a visually similar setting across different source sizes.
