Free screenshot check

App Store screenshot size checker

Check PNG and JPEG screenshots locally against Apple's current iPhone and iPad pixel sizes, orientation, file format, and transparency rules.

Your image stays entirely in the browser and is never uploaded or stored.This tool checks one image file technically. Visual claims, sequence, copy, and consistency with the release build remain part of the complete app review.

Check a screenshot locally

Choose a PNG or JPEG export. LaunchLint checks dimensions, orientation, format, and transparency inside your browser.

Image analysis runs locally. LaunchLint does not store or transfer the file.

Which App Store screenshot size is correct?

Apple accepts defined pixel dimensions for each display class. This free checker reads width, height, format, and transparency locally and shows the matching iPhone or iPad classes.

Exact pixels, not just aspect ratio

A matching aspect ratio is not enough. Current large-iPhone portrait options include 1260 × 2736, 1290 × 2796, and 1320 × 2868 pixels.

For iPad apps, Apple currently lists 2064 × 2752 and 2048 × 2732 among the 13-inch portrait options. Landscape uses the reversed values.

Format and transparency

Apple accepts JPEG, JPG, and PNG but no alpha channels or transparency. A PNG can look opaque while still containing an alpha channel, so the checker reads the PNG structure rather than only the extension.

Technical validity does not prove a useful screenshot. Copy must remain readable and every shown capability must exist in the submitted build.

From one file to a gallery

Validate master exports and every localized version before upload. Consistent dimensions and naming keep stale assets out of the final set.

This free tool reviews one file. The complete LaunchLint review connects listing claims, app configuration, permissions, and the release candidate.

Example: current large iPhone

Input
PNG, 1290 × 2796 pixels, portrait, fully opaque.
Result
The dimensions match the 6.9-inch iPhone class. Format and alpha are technically plausible; the visual claim still needs editorial review.
