App Store screenshot sizes and upload requirements

For Apple’s required iPhone Dynamic Island (medium display) group, use 1206×2622 or 1179×2556 px in portrait; iPad apps also need a 13-inch set. Upload PNG or JPEG without alpha. The dimensions and rules below were checked against official documentation on 4 November 2026, including the separate conditions for larger iPhone groups.

Which iPhone sets should you prepare?

Apple’s reference names the medium Dynamic Island group under Required device sizes. Its detailed table also requires large Face ID screenshots when large Dynamic Island screenshots are absent. To account for both statements, our recommended submission plan includes the medium set plus either large Dynamic Island images or the large Face ID fallback. Check the required groups and inherited images in your app’s Media Manager before considering the set complete. Avoid assuming that one large iPhone set covers every requirement.

Use scaling only where the interface stays accurate

Apple permits automatic scaling when the interface is consistent across device sizes and localizations. Inspect the result before relying on it. A tablet sidebar, a compact navigation bar, or a different arrangement of controls is a reason to capture that layout separately. When adapting artwork, create the destination canvas first, preserve the screen capture’s proportions, and reposition the headline and device around it. Stretching the entire finished image changes the interface as well as the frame. Capture the iPad experience itself when the tablet layout differs.

Export without an alpha channel

An image can look completely opaque and still contain an alpha channel. Flatten the composition onto its intended background, then export an RGB PNG without alpha or a JPEG. Inspect the saved file’s channels as well as its visible corners. In mockup.best, the named store-image presets use an opaque export path and restrict output to PNG or JPG. Custom dimensions do not automatically inherit that path: for a custom screenshot, choose JPG or remove alpha from the PNG separately. Renaming a file extension does not perform either conversion.

Make the screenshot show a usable app

Apple’s screenshot guidance requires more than half of the images for each supported device to show the app in use: with four screenshots, at least three must do so. Text and image overlays are permitted, but they must leave the main functionality visible. Build the composition around a real feature screen rather than a hardware render, splash screen, or generic login page. Use fictional account details, and identify any featured functionality that requires an additional purchase. Before exporting, compare the screen inside the mockup with the interface in the version you are submitting.

Choose the sequence and localization deliberately

Apple accepts one to ten screenshots per device size. Start with the result someone can achieve, then explain different capabilities. For a planning app, try an organized schedule, creating an event, and reviewing a week. Choose the sequence around your app’s main tasks. Keep separate working sets for each language and device layout. After translating headlines, check line breaks and capture the corresponding interface language; also check that every localization’s set still contains a majority of images showing the app in use.

Google Play uses a different size rule

For the general phone screenshot requirements, Google specifies JPEG or 24-bit PNG without alpha, sides from 320 to 3840 px, and a long side no more than twice the short side. Publishing requires at least two screenshots overall; each supported device type has up to eight slots. For apps to qualify for recommendation formats using screenshots, Google asks for at least four at 1080×1920 portrait or 1920×1080 landscape minimum, in those respective aspect ratios. A 1290×2796 Apple image exceeds the 2:1 limit. Recompose it on a Play canvas instead of squeezing the artwork.

Match the store requirement to the actual export preset

The reference table separates accepted dimensions from mockup.best’s named presets. Its iPhone preset exports 1290×2796, which belongs to Apple’s large Dynamic Island group; it does not produce the required medium group. For that group, use Custom dimensions with one of the listed pixel pairs and check the finished framing. The iPad preset exports 2064×2752, while the Play phone presets provide both orientations. A store label describes an export size, not complete submission coverage. Plan every required group before generating a batch, then verify the resulting files individually.

Diagnose a dimensions error before resizing again

Compare the file’s actual width and height with the destination group, using the table below. Confirm whether the artwork is portrait or landscape, and check that an export scale multiplier has not doubled the intended pixels. If the dimensions match, inspect format and alpha next. In mockup.best’s screenshot size checker, an exact-match result refers to sizes the product exports as presets; it is not a complete list of Apple-accepted dimensions. For example, a valid medium-group screenshot can lack a preset match. Read the dimensions and channel results separately.

Check the final placements in App Store Connect

Open the app version, then Product Page Information and App Previews and Screenshots. Choose the localization and device tab before adding files. View All Sizes in Media Manager lets you inspect other sizes, including scaled images. Review ordering, captions, interface language, and layout-specific replacements. You can also upload previews and screenshots through Asset Library and select compatible approved assets for a placement. Organize source captures and final exports by store, device group, language, and sequence so you can identify the files affected by a later interface change.
