A technical reference for iOS developers and product teams on meeting every App Store screenshot requirement: exact dimensions, file constraints, Apple review policies, and submission rules.

Preparing marketing assets for iOS submission requires adhering strictly to Apple's technical constraints. Unlike general web images or social media graphics, App Store Connect validates uploaded files programmatically during the submission process. Uploading an asset with incorrect pixel dimensions, an invalid color space, or active transparency will immediately trigger an error and block build processing.
Before designing your screenshot sets, ensure your rendering export pipeline complies with these core specifications:
Critical validation requirement: App Store Connect checks image metadata upon file transfer. If a PNG file contains an alpha channel — even if every pixel is fully opaque — the parser will reject the file with the error message: "Images cannot contain alpha channels or transparency."
Apple categorizes iOS, iPadOS, watchOS, and visionOS hardware into distinct display tiers. You do not need to create unique graphics for every historical device model. Instead, App Store Connect requires assets for the largest screen tier in each active device family and downsamples them automatically for smaller devices.
The table below summarizes the target resolutions and submission status across primary device families:
| Device Tier | Pixel Dimensions (Portrait) | Aspect Ratio | Target Hardware | Status |
|---|---|---|---|---|
| 6.9-inch iPhone | 1320 × 2868 | 19.5:9 | iPhone 16 Pro Max, 16 Plus | Primary |
| 6.9-inch iPhone (Alt) | 1290 × 2796 | 19.5:9 | iPhone 15 Pro Max, 15 Plus, 14 Pro Max | Accepted |
| 6.5-inch iPhone | 1284 × 2778 | 19.5:9 | iPhone 13 Pro Max, 12 Pro Max | Optional |
| 5.5-inch iPhone | 1242 × 2208 | 16:9 | iPhone 8 Plus, 7 Plus, 6s Plus | Legacy |
| 13-inch iPad | 2064 × 2752 | 4:3 | iPad Pro 13-inch (M4) | Primary |
| 12.9-inch iPad | 2048 × 2732 | 4:3 | iPad Pro 12.9-inch (2nd–6th gen) | Accepted |
| Apple Watch | 410 × 502 | 4:5 | Apple Watch Series 10, Ultra 2 | Watch App |
| Apple Vision Pro | 3840 × 2160 | 16:9 | Apple Vision Pro (Spatial App) | visionOS |

When you upload a set of 6.9-inch iPhone screenshots (1320 x 2868 pixels), App Store Connect automatically scales those images to fit 6.5-inch, 6.3-inch, 6.1-inch, and 5.8-inch device displays. This downsampling algorithm preserves aspect ratio while maintaining sharpness across physical OLED and LCD screens.
However, scaling down does not bridge aspect ratio differences between 19.5:9 notchless devices and legacy 16:9 home-button devices (such as the 5.5-inch iPhone 8 Plus display). If your app supports legacy devices or requires custom typography layout per screen size, you can manually upload targeted asset sets to override the default inheritance behavior.
App Store Review Guideline 2.3.3 governs screenshots specifically, requiring that they accurately show the app in use. Apple human reviewers evaluate app store assets prior to release. Violating metadata guidelines leads directly to rejection during app review, forcing developers to resubmit assets and restart the review queue.
The most frequent screenshot rejection triggers include the following compliance issues:
Before submitting your release candidate, cross-reference your assets against Apple's official screenshot specifications to verify compliance with current review policies.
Reviewer tip: Ensure that all user data depicted in screenshots (profile pictures, names, account balances, message text) is placeholder content or properly licensed stock media. Demonstrating real personal identifiable information (PII) without consent violates privacy policies.
App Store Connect enables localized product pages for every territory where your app is available. When a user views your listing, the App Store renders screenshots matched to their device system language.
Managing localized screenshot sets requires careful planning around asset counts and language fallbacks:
While technical specifications define file limits, visual composition dictates conversion performance. App Store search results render your first few screenshots in a compact layout, making clear hierarchy essential.
App Store Connect permits uploading screenshots in portrait or landscape orientation. However, mixing portrait and landscape images within the same display size set creates inconsistent presentation. Choose one primary orientation based on your app's native layout:
Modern iPhone screens incorporate rounded display corners, home indicator bars, and Dynamic Island cutouts. When framing raw UI captures inside promotional templates, adhere to these composition rules:
Developers launching multi-platform apps must manage different screenshot asset pipelines for iOS and Android. App Store Connect and Google Play Console enforce distinctly different asset policies and file specifications.
The table below contrasts the main submission rules between both platforms:
| Requirement | Apple App Store Connect | Google Play Console |
|---|---|---|
| Maximum Screenshots | 10 per display size | 8 per device type |
| Minimum Screenshots | 1 per device family | 2 per store listing |
| Dimensional Rules | Strict fixed pixel resolutions | Flexible aspect ratios (320px to 3840px) |
| Alpha Channel Transparency | Strictly rejected (No alpha) | Accepted in specific contexts |
| Tablet Assets | Required if iPad is supported | Required for tablet feature eligibility |

Following a structured production workflow reduces the risk of App Store Connect upload errors and reviewer rejections prior to launch day:
Automating asset generation eliminates manual export errors across multiple device sizes. Using dedicated design tools allows product teams to frame raw UI captures, apply localized caption overlays, and export complete store-ready asset packages effortlessly.
MockupLite turns raw app captures into perfectly sized, framed App Store screenshot packages. Apply captions, device bezels, and background gradients in one click — exported instantly without alpha channels.
Open the studio →You must upload at least one screenshot for each device family your app supports. Images must be in PNG or JPEG format, use RGB color space, and contain no alpha transparency. The largest required size for iPhones is the 6.9-inch display (1320 x 2868 pixels), and for iPad, it is the 13-inch display (2064 x 2752 pixels).
Apple prohibits transparency in screenshots because transparent pixels can render unpredictably against the dark or light backgrounds of the App Store interface. App Store Connect will throw an explicit upload error if your PNG file includes an alpha channel. You must flatten all transparency before uploading.
No. Apple only requires screenshots for the largest display size in each device family. Uploading a set for the 6.9-inch iPhone automatically scales down for 6.5-inch, 6.3-inch, 6.1-inch, and smaller iPhones. You only need to upload smaller size sets if your UI or text overlay scales poorly.
Yes. Adding text captions and rendering UI inside device frames is standard practice. However, Apple guidelines require that the screenshots accurately represent the actual app experience. The device frame shown must also match the screen aspect ratio and hardware style of the targeted device size.
App Store Connect allows up to 10 screenshots per display size. You must upload at least 1 screenshot per active device family. The first 2 or 3 screenshots are the most critical because users see them directly in search results without tapping into your listing.
Apple requires rigid, exact pixel dimensions for specific hardware models (such as 1320 x 2868 for 6.9-inch iPhones) and strictly bans alpha channels. Google Play accepts a wider range of aspect ratios (16:9 or 9:16) with flexible dimension boundaries (320px minimum up to 3840px maximum) and permits up to 8 screenshots per device type.
