Tips
The corner radius is a percentage of the shorter side of the image, so 50% turns a square into a circle and a rectangle into a pill shape; “circle / oval” does the same in one click. The border is drawn inside the image edge, following the rounded outline, so the picture keeps its size. Corners are truly transparent in the PNG, so the image sits cleanly on any background — the checkerboard above just shows where the transparency is. To round only the corners for a website you can also use the CSS border-radius property, but a PNG works everywhere, including in emails and documents.
