What is an iOS squircle and how does it differ from a standard rounded rectangle?

An iOS squircle uses continuous mathematical curvature so the transition between straight lines and rounded corners is organic and seamless.

Will the cropped areas outside the curves remain transparent?

Yes, exported PNG files retain complete 32-bit alpha transparency in the clipped corner areas.

Does rounding the corners degrade photo sharpness or resolution?

No, clipping paths are rendered at the native pixel resolution of your source image.

Frequently Asked Questions (FAQ)

A standard rounded rectangle connects straight edges to circular quarter-arcs, creating a noticeable curvature discontinuity where the arc begins. An iOS squircle (superellipse) continuously alters its curvature from the center to the corner, producing the organic, signature look seen on Apple iOS app icons and macOS windows.

Yes! When "Outside Area" is set to "Transparent (32-bit PNG)", all pixels outside the rounded boundary have 0% alpha opacity. You can place the resulting image on dark, light, or patterned backgrounds without white corner artifacts.

No. The original pixel dimensions of your uploaded photo are preserved unless you deliberately choose a cropped aspect ratio (e.g. 1:1 Square). The clipping path operates at native image resolution.
