About this tool
Add a coloured border, padding or transparent margins and round the corners of any image — preview live, export PNG or WebP.
Padding enlarges the canvas around the picture; rounded corners make pixels outside the radius transparent with an anti-aliased edge; the border is drawn as an outer frame that follows the same radius.
Example: a 1200 × 800 screenshot with 40 px white padding, a 6 px dark border and 24 px radius becomes 1292 × 892.
Transparent corners need PNG or WebP. JPG has no transparency, so corners become white.
