Details and tips
How it works
A rounded rectangle clips the original image without changing its width or height. The corner radius ranges from zero to half of the shorter edge; the removed corner pixels become transparent.
Made for everyday images
Create rounded product cards, thumbnails, avatars and presentation graphics.
