Round image corners
Rounded corners make a screenshot read as a window rather than a rectangle of pixels. Set the radius, keep the background transparent, export as PNG.

Questions
Are my images uploaded anywhere?
No. Everything runs in your browser using the Canvas API — the file never leaves your machine, and the tool keeps working if you go offline after the page loads. There is no account, no queue, and no server-side copy to delete later.
Why must I export as PNG?
Rounded corners are transparency. JPG has no alpha channel, so the corners would be filled with a solid colour instead of being cut away. PNG and WebP both preserve them.
