    Rounded corners for a modern look

    App screenshots, blog cover images, product cards and slides look softer and more modern with rounded corners. This tool rounds all four corners with the radius you choose and leaves the area outside transparent.

    The same look at any size

    The radius is set as a percentage of the shorter side, so a small thumbnail and a large cover image look equally rounded. A 50% radius turns a square into a circle and a rectangle into a pill.

    Transparency preserved

    Download as PNG or WebP to keep the corners transparent. Your image is processed only in your browser.

    1. Upload the image whose corners you want to round.

    3. Check the preview.
    4. Download as PNG or WebP.

    Why use this tool?

    Get images with rounded corners as ready files for places where you can't use CSS, such as email, slides and social media.

    FAQ

    What does a 50% radius do?

    It fully rounds the short sides, turning a square into a circle and a rectangle into a pill shape.

    Why do the corners look white?

    A program showing the image as JPG may render transparency as white. Keep it as PNG or WebP.

    Should I use CSS on my website instead?

    On a web page the CSS border-radius property is more flexible; this tool is for when the file itself must have rounded corners.
