Rounded Corners Image: what the result contains
Apply a configurable corner radius to an image and export a transparent PNG.
Corner transparency depends on the output format
Rounded corners need transparency if the outside area should disappear. Formats without alpha transparency may fill those corners instead of keeping them clear.

Where Rounded Corners Image stops
Choose an alpha-capable output when transparency matters; otherwise use a solid background intentionally.
Example and result checks
A square card graphic can use a modest corner radius to fit a dashboard design. A radius that looks balanced on a large preview may cut too much from a small icon. Preview against both light and dark backgrounds so the new transparent corners are obvious.
If the exported format supports transparency, the corner regions can remain transparent rather than being filled with a colour. Check that the download really retains transparency before adding it to a website. Do not use this operation when a submission portal requires opaque, rectangular photographs.
