Frequently Asked Questions

Is this tool free?
Yes, 100% free. No signup, no watermarks.
Why does the output need to be PNG?
Rounded corners require transparency. PNG supports transparency; JPEG does not.

Yes. Set the corner radius to 50% of the image dimensions to create a perfect circle.
Is my image uploaded to a server?
No. All processing happens in your browser using the Canvas API.
Will the output have a white background?
The corners are transparent — they will appear as white on white backgrounds but transparent when overlaid.
