Round Corners

Softens the sharp corners of any image into smooth curves — a small detail that shows up everywhere from app icons to profile thumbnails to card-style layouts on a website. Set the corner radius and the tool applies it evenly, exporting with proper transparency where the corners are cut away.

How to use it

Upload the image, drag the radius slider (or type an exact pixel value), and watch the preview update live. A small radius gives a subtle softening; a larger one moves toward a more rounded, app-icon look. Export as PNG to keep the cut corners transparent — exporting as JPEG will fill them with a background color instead.

FAQ

Will this work if I need the corners fully transparent, not just a different color? Yes, export as PNG — the rounded-off corner areas become transparent rather than filled, which is what most UI and app-icon use cases need.

What’s the difference between this and Crop circle? Round corners softens all four corners of a rectangle while keeping the overall shape rectangular; Crop circle crops the entire image into a full circle. Use rounded corners for a card or icon look, and circle crop for an avatar-style shape.

Can I set a different radius for each corner? The default is a uniform radius across all four corners for consistency; for asymmetric shapes, a general image editor would be needed instead.

Does this change the image dimensions? No, the canvas size stays the same — only the corner pixels become transparent (or filled, on JPEG export).
