Give a photo, avatar, card graphic, or screenshot smoothly rounded corners. The browser clips the original pixels to your selected radius and exports a PNG so the area outside each curved corner stays transparent.
How to use Rounded Corners
- Choose a JPEG, PNG, or WebP image.
- Set the corner radius in pixels.
- Process the image, inspect the transparent corners, and download the PNG.
Things worth knowing
- The output keeps the source width and height.
- The radius is limited to half the shorter side, which prevents overlapping corners.
- PNG is required because JPEG cannot preserve transparent corners.
Frequently asked questions
Why is the output always PNG?
PNG preserves transparency around the curved corners. JPEG would replace those transparent pixels with a solid color.
Does rounding crop the image dimensions?
No. The canvas dimensions stay unchanged, but pixels outside the rounded shape become transparent.
