## What this tool does
Crop to a square with rounded corners or a perfect circle — avatar and UI ready.

## Typical user problems
- Avatars, UI thumbnails and badges need shaped PNGs with real transparency. Cropping in a paint app leaves the corners white unless you know exactly where the alpha tools hide.
- Every app crops avatars to circles — and the corners of your rectangular photo ruin the preview. Deliver a true circular PNG that drops in perfectly.
