FAQ
Can the rounded image keep a transparent background?
Yes. Exporting as PNG keeps the corners transparent, ready to layer over any background; exporting as JPEG fills the corners with white.
Can the four corners have different radii?
Yes. With “sync corners” on, all four change together; turn it off to set top-left, top-right, bottom-right and bottom-left separately.
Are my images uploaded to a server?
No — everything runs locally in your browser, so your images never leave your device.
