or click to browse · JPG, PNG, WEBP, BMP, GIFSharp corners look technical; rounded corners look designed. It is a small change with an outsized effect — the same photo feels softer, friendlier and more at home on a card, a slide, or a social post when its corners are rounded.
Drag the radius slider from a subtle 5% to a full 50% and watch the preview update live. Transparent PNG output keeps the corners see-through on any background, which is what you want for web pages and presentations; white corners suit documents and print.
At 50% on a square photo, rounded corners become a circle — for avatars, the dedicated circle cropper is the faster route.
