Frequently asked questions
Why is the output PNG?
Because JPG does not support transparency: rounded corners need an alpha channel.
Can I make a circle?
Yes: with a square image, push the radius to the max and you get a perfect circle.
Which formats are accepted?
JPG, PNG, WEBP, AVIF, BMP and GIF (first frame). The output keeps the original format when possible.
Is my image uploaded to a server?
No. All processing happens on your device using the browser itself; the image never leaves it.
