Frequently asked questions
What does the radius percentage mean?
It is a share of the image's shorter side: 50% makes fully round ends, 10–20% gives soft corners.
Why are my corners white in JPG?
JPG has no transparency, so corners are filled with a color (white by default). Use PNG or WebP to keep them transparent.
Does it change the image size?
No. Dimensions stay the same; only the corners are removed.
Are my images uploaded to a server?
No. Files are decoded, processed and re-encoded by your browser using the canvas API and Web Workers. Nothing is sent to any server, and there is no account or storage. Closing the tab discards everything.
