App Store Screenshot Sizes and Formats

Mac screenshots must be 16:10 and one of four sizes: 1280 x 800, 1440 x 900, 2560 x 1600 or 2880 x 1800 pixels. These are the only Mac pixel sizes in Apple's list, so export one of them rather than a custom crop.

• Formats: .jpeg, .jpg or .png.
• No alpha channel or transparency. A PNG exported with transparency is a common upload error; flatten it first.
• At least one screenshot is required per size, and up to ten can be uploaded; see how many screenshots fit.

For the exact iPhone and iPad pixel dimensions, check Apple's current screenshot specifications in App Store Connect help; this page does not list them because they change with new devices.

A hypothetical Mac app with a 2880 x 1800 capture exports once at 16:10. A 2560 x 1600 export has the same ratio, so a single master image can serve either size after resizing. A 1920 x 1080 screenshot is 16:9, so it is not one of the four sizes.

Depending on orientation, the first one to three screenshots appear in search results when no app preview is available. Guideline 2.3.3 says screenshots should show the app in use, not merely title art, a login page or a splash screen. Pair this with the app preview length, since a preview takes the place of those search-result images.

Look up every limit at once in the metadata limits reference and read how the first words and images work together in the title and subtitle guide.
