UpdatedNow with the iOS 26 icon shape

How it works

Square in, squircle out

App icons don't have ordinary rounded corners. Their curves ease gently into the straight edges, and iOS 26 changed the shape again. Squircle cuts any image to the real thing.

Corner styles

Three ways round

The same picture, exported from Squircle in each style.

Why not just round the corners?

A rounded rectangle joins a circular arc straight onto each edge, so the bend starts suddenly. App icon corners start curving further along the edge and bend gradually, which is what makes them look smooth.

The iOS 26 corner is a little rounder again. Next to real app icons the difference shows, so Squircle draws each shape exactly and your artwork matches the icons around it.

Borders and shadows

Finish it off

Borders follow the curve of the corners. The shadow is part of the PNG, with the picture made slightly smaller so the shadow fits.
