About Round Image Corners

Rounded corners soften screenshots and product shots; a circle is the usual shape for profile pictures and avatars. The area outside the shape becomes transparent.

The result is always a PNG, because JPG cannot store transparency. Circle mode cuts a circle from the centre of the image.

For a perfect circle

Crop the photo to a square first with the image cropper, with the face or subject in the centre. The circle then fits the whole square.

Questions

Why is the result a PNG?

The corners are transparent, and PNG keeps transparency everywhere. JPG would fill them with a colour.

What does the radius mean?

It is a percentage of the shorter side. 10% gives gently rounded corners; 50% gives the roundest possible shape.

How do I choose the centre of a circle?

Crop the image to a square around your subject first with the image cropper.
