How does corner rounding work?
Corner rounding applies a border-radius-style clipping path to an image, replacing sharp 90° corners with smooth arcs. The radius value (in pixels) determines how large the rounded curve is — a small radius gives a subtle softening, while a radius equal to half the image's shortest side produces a full circle or pill shape. This tool draws the rounded shape on a <canvas> and exports the result as PNG with transparent corners, so the rounded image can be placed on any background.
Common use cases
- Profile pictures — create rounded avatar images for social media, forums, or messaging apps.
- App store screenshots — round screenshot corners to match device frame mockups.
- Marketing materials — soften image edges for banners, cards, and email newsletters.
- UI design — prepare rounded image assets for interfaces that require pre-rounded images (e.g., email HTML).
- Thumbnails — create visually consistent rounded thumbnails for galleries and listings.
