About Round Image Corners
Modern UI design emphasizes soft rounded corners over harsh right angles. Modifyle lets you specify exact corner radius in pixels to match modern iOS, Android, and macOS design aesthetics.
The tool uses quadratic and circular arc clipping to ensure curves are smooth and free of jagged pixel staircase artifacts.
When exporting with a transparent background in PNG or WebP format, outer corner pixels are saved with full alpha transparency ($A = 0$), allowing your image to sit cleanly on any background color or webpage layout.
All calculations are computed locally in your browser with zero latency and zero data leakage.
