FAQ
How do I add rounded corners to an image?
Upload an image, choose a corner radius, and process it. The result can be downloaded after preview.
Why is PNG the default output?
PNG supports transparency, which is useful for transparent rounded corners.
Can JPG output have transparent corners?
No. JPG does not support transparency, so the output uses a white background.
Can I make a rounded profile image?
Yes. Use a square source image and increase the radius to create a rounded or circular profile-style image.
Will my original image be changed?
No. The tool creates a new downloaded file and does not modify your original image.
Are images uploaded?
No. Rounded corners are generated locally in your browser.
