How to use Round PNG Corners
- 1. Upload the PNG. Add the image whose sharp corners you want softened, such as graphic.png, so the tool can apply rounding to each edge.
- 2. Set the corner radius. Enter Corner radius (px), such as 40, to control how deeply each right-angle corner is curved into a smooth arc before becoming transparent.
- 3. Download the rounded PNG. Save the result, such as graphic.png with smooth transparent rounded corners, once the radius matches the card or button style you need.
When to use Round PNG Corners
Round PNG Corners softens an image's sharp right-angle corners into transparent rounded edges, matching the rounded-rectangle style common across modern interfaces. It is a quick way to make a plain rectangular image fit a card-based design.
- Matching a card component's border radius. A UI card component uses a consistent border radius across the app, and an image dropped into it needs matching rounded corners rather than sharp ones that clash visually.
- Softening a thumbnail in a gallery grid. A photo gallery grid uses rounded thumbnail tiles as its visual style. Rounding each source graphic's corners to the same radius keeps the grid consistent.
- Preparing an avatar-style image. A profile picture needs rounded corners to match a platform's avatar style, short of a full circular crop. Rounding the corners at a chosen radius achieves that softer look.
