App store and play store screenshot size checker

Which App Store slot each screenshot fits, whether Google Play accepts it, and the exact problem otherwise.

Drop PNG or JPEG screenshots here, or choose files. Nothing leaves this tab.
Check filesType sizes

Add screenshots or type sizes and press Check. Apple takes an exact pixel size per device class; Google Play takes a range of sizes but refuses alpha and ratios past 2:1.

Slot sizes and store rules were checked against the Apple and Google help docs on 19 Sept 2026 ; stores change them, so treat a near miss as a prompt to re-check the source. Content rules (real app UI, device frames) are reviewer decisions and are not checked here.
