For iPhone app screenshots, a corner radius around 20% gives a clean, native-looking rounded corner that matches modern iOS design language. Using 50% (fully round) would make your screenshot look like an app icon rather than a device screen, so avoid that. For iPad screenshots, slightly less rounding (around 15%) works better due to the larger aspect ratio. Always preview before submitting.
Some platforms compress uploaded images and may add a background color to transparent PNGs. Your rounded corners can appear as solid squares if the platform doesn't preserve transparency. Fix: Download with a solid background color that matches where you'll use it — our color picker lets you choose exact hex codes. For Instagram posts, white (#FFFFFF) or black (#000000) backgrounds work well. For websites, pick a color that matches the page background.
