About this tool
This page opens the border tool with a 20 px black frame preset applied to the first image you drop — check the live preview and download when it looks right.
A black border adds instant contrast: light photos stop bleeding into white pages, screenshots get a crisp boundary, and prints gain the classic dark-frame finish that makes colors appear deeper.
From here you can thicken the frame up to 100 px, pick any other color, or round the corners — everything renders locally in your browser and exports as a PNG.
Example. A border width of 8 and a corner radius of 24 draw an 8-pixel solid stroke and clip the picture to a 24-pixel radius.
Limit. The border is one solid color; gradient frames and image frames are not drawn.
