Rounded corners
Upload an image, drag the slider to set the corner radius, all the way to a pill shape (or a circle, if the photo is square), and download the image with transparent corners.
JPG, PNG, WebP… your image never leaves your device.
Why rounded corners can't be saved as a JPG
The JPG format doesn't support transparency: save rounded corners as a JPG and the curves get filled with solid white, which sticks out the moment the file lands on any colored background. That's why rounded corners are saved as PNG, or as WebP if the photo was WebP: both keep the transparency, and the image sits cleanly on whatever is behind it, websites, slide decks, thumbnails, social media graphics.
From a subtle curve to a pill or a circle
The slider sets the radius as a percentage of the shorter side: around 10–20% you get the soft "card" look common in modern interfaces, while at 100% the curves meet, on a square photo the result is a perfect circle, ideal for avatars and profile pictures. On rectangular images, 100% produces a pill shape, the kind often used for badges and buttons.
With the radius at zero nothing is transparent, and the file is saved in the photo's format, at full resolution. For a perfect circle even from a rectangular photo, with the face where you want it, there's Round profile photo.
