Frequently asked questions
Is the area outside the corners transparent?
Yes. The export is a PNG: the cut corners are fully transparent, ready to sit on any background.
Why set the radius as a percentage?
The radius is computed from the shorter side, so the look is identical whether the image is 200 or 2000 px. At 50%, a square image becomes a circle.
Is my image uploaded?
No. Rounding happens in your browser via the canvas. Your image never leaves your device.
Is quality preserved?
Yes. The image is drawn at its original size; only the corners are made transparent, with no recompression.
