      Rounded corners soften the hard edges of an image, the look used for cards, avatars, thumbnails and app icons. This tool clips your image to a rounded rectangle and makes the four corner areas transparent, with a radius chosen automatically from the image size.

      Because the corners must be transparent, the result is always saved as a PNG (which supports transparency) regardless of the input format. It drops straight onto any background - a card, a coloured panel or a web page - with neat rounded corners.

      Everything runs entirely locally in your browser on a canvas (no upload, even offline) - your image never leaves your device. The corner radius is sized automatically for a balanced look. Animated images are flattened to a single frame.

      In 3 steps

      1. Drop or tap your image (PNG, JPEG or WebP).
      2. It is clipped to a rounded rectangle on a canvas; the corners become transparent.
      3. Download the rounded PNG (several at once as a ZIP).

      Limitations: Clips an image to a rounded rectangle; the four corners become fully transparent. The output is always a PNG (so the transparency is kept), at the input dimensions. The corner radius is derived automatically from the image by default, or can be set to a fixed value via a slider. Animated inputs are reduced to a single frame.

      FAQ

      Is my image uploaded?

      No. The crop runs entirely locally in the browser on a canvas - even offline. Your image never leaves your device.

      Why is the output a PNG?

      The corners must be transparent. JPEG cannot store transparency, so the result is always a PNG, which keeps the corners see-through.

      How big is the corner radius?

      By default it is sized automatically from the image for a balanced look; use the slider to set a fixed radius in pixels instead.

      Is it good for cards and avatars?

      Yes. Rounded corners are the standard look for cards, avatars, thumbnails and app icons, sitting neatly on any background.
