Frequently asked questions
Will the corners be transparent?
Yes — as long as you export as PNG or WebP. JPG has no transparency, so it fills the corners with a solid background colour instead.
Is the radius the same on every image size?
Yes. The radius is set as a percentage of the shorter side, so the same setting looks consistent whether your image is small or large.
Are my images uploaded anywhere?
No. All processing happens on your device in the browser — nothing is uploaded to a server.
