How to use
Choose a radius no larger than half the shorter side. Outside corner pixels become transparent.
Limits and behavior
Uses pixel-center circular clipping. Edges are not antialiased, and output is PNG. Still PNG, JPEG and WebP only; 20 MB, 4 megapixels and 4,096 pixels per side. Processing stays on your device. Exports apply orientation and discard source metadata. PNG output preserves transparency unless the selected operation composites it.
Give an image rounded corners
Apply a corner mask so a picture can sit neatly on rounded cards and graphics.
Will a JPEG file retain transparent rounded corners?
JPEG cannot store transparency; choose an output format that preserves alpha, such as PNG.
