Frequently asked questions
How do I round the corners of an image?
Drop or select an image, then drag the radius slider to set the corner roundness. At 50% you get a fully rounded shape. The preview updates in real time so you can see the effect before downloading.
What radius gives a circle shape?
Setting the radius to 50% on a square image produces a perfect circle. On a rectangular image, 50% gives a fully rounded rectangle. For a true circle crop, use our dedicated Circle Crop tool instead.
What format should I download?
Use PNG if you need the transparent area outside the rounded corners to remain transparent. JPEG does not support transparency and will fill the corners with a solid color. WebP supports transparency and offers smaller file sizes.
