App Store Screenshot Specifications 2026: Sizes, Formats & Checklist
App Store screenshot specs change by device family, but the launch workflow is stable: design the strongest story once, then export the required screenshots in the correct sizes and formats.
Upload checklist
- Upload one to ten screenshots for each supported device set.
- Use JPEG, JPG, or PNG files accepted by App Store Connect.
- Plan screenshots around the largest required display sizes first.
- Check each localization before submitting a new app version.
- Keep screenshots visually consistent with app previews and the icon.
The key App Store screenshot rules
Apple's screenshot specification reference lists the accepted device sizes and says each set can include one to ten screenshots. App Store Connect accepts JPEG, JPG, and PNG screenshots. Apple also notes that if the UI is the same across device sizes or localizations, you can provide the highest-resolution screenshots and let Apple scale down for smaller sizes.
Design before exporting
The spec tells you what files are accepted, but conversion depends on the story. Build a screenshot set around the first three frames: problem, product proof, and outcome. Then export the same system across iPhone, iPad, and localized variations instead of rebuilding each size manually.
Format
Use accepted JPG, JPEG, or PNG files.
Count
Prepare one to ten screenshots per set.
Order
Put the clearest value proof first.
