Questions

Frequently asked questions

Why is the output a PNG file?

The PNG format is used because it supports transparency. The areas outside the rounded corners are made transparent, which formats like JPG do not support.

Can I make each corner a different radius?

This tool applies the same radius to all four corners for a uniform look. It does not support individual corner adjustments.

What happens if I use a very large radius?

Up to a point. The radius stops at 200 pixels, so a square 400 pixels or smaller becomes a full circle; a larger one gets rounded corners. A non-square image becomes a pill shape.

How many images can I add at once?

There is no fixed limit. Past about 500 MB the page warns you before it starts. Files with the same name get a number added inside the ZIP. Older browsers are told plainly that they cannot run this.

Background

The Role of Rounded Corners in UI Design

Set a pixel radius to define the curve of the corners. Pixels outside the rounded mask become transparent, making it ideal for web design.

  • Rounded corners are easier on the eyes than sharp corners. They feel more organic and approachable, making designs seem friendlier.
  • The smooth curve of a rounded corner directs attention inwards towards the content, unlike a sharp corner which can lead the eye outwards.
