What is Round Image Corners?
Round Image Corners applies smooth, anti-aliased rounded corner radii or full circular clipping to any photo. It exports transparent PNG assets ready for modern UI cards, web components, and circular avatars.
Unlike legacy online utilities that upload sensitive media and documents to remote cloud storage, Shadow Toolkit executes this entire operation directly within your browser's local runtime. Your raw data never crosses the network.
Key Capabilities
- Adjustable corner radius slider from subtle 8px rounding to full circle/pill clip
- Smooth anti-aliased corner curves with zero pixelation or jagged edges
- Exports 32-bit transparent PNG format to seamlessly fit any web background
- Optional border stroke around the rounded boundary
- 100% private local execution with zero network transmission
