IAP App Review Screenshot checker
Check the pixel size of an in-app purchase or subscription App Review Screenshot. Apple’s written rule and dated App Store Connect reports are not the same thing.
Check an App Review Screenshot
The result stays on this device.
What this field is
Apple says the App Review Screenshot is used for review purposes only and isn’t displayed on the App Store. Upload a screenshot that meets any of the screenshot specifications your app supports. Source: In-app purchase information, checked 2026-10-05.
The promotional Image is a different field: a 1024 × 1024 flattened JPEG or PNG, RGB, 72 dpi, without rounded corners. It is not the App Review Screenshot. A 1024 × 1024 file is that Image, not this screenshot.
What a result means
Apple’s IAP help points at the same screenshot specification used for product-page screenshots. App Store Connect’s IAP upload field has still been reported to reject some of those listed sizes.
- 640 × 920 and 640 × 960 are the 3.5-inch iPhone portrait pair on that specification. Independent reports from 2025–2026 say Connect accepted those sizes for the IAP App Review Screenshot, including Apple Developer Forums thread 813399 in January 2026.
- 6.9-inch iPhone sizes such as 1320 × 2868 and 1290 × 2796 are listed for product-page screenshots. Independent reports from 2025–2026 say Connect rejected them for this IAP field, including thread 793674 in July 2025.
- This page does not invent a complete unofficial whitelist. A listed product-page size without a dated IAP report is labeled as listed, not as accepted.
- The default example is 640 × 920 because that size has a dated acceptance report. 1320 × 2868 is a product-page match and is the wrong example for this field.
Apple says you can upload one to 10 screenshots in .jpeg, .jpg, or .png format. Images can’t include alpha channels or transparencies. Some developers also reported that a screenshot taken in Safari uploaded when another source of the same pixels did not. This tool does not inspect the capture app, DPI metadata, or color profile, and it does not submit the file.
Use the product-page screenshot checker for App Store screenshots 1–10. The size table is on the screenshot sizes page.
