App Store Screenshot Generator for iPhone Releases

According to Apple's screenshot specifications (opens in a new tab), you can upload one to 10 screenshots per display size in .jpeg, .jpg or .png format. Images can't include alpha channels or transparency. Apple states no maximum file size on that page.

Smaller displays fall back to larger ones. Apple's upload guide (opens in a new tab) says that if your interface is the same across device sizes and localizations, you only need the highest-resolution set, which scales down automatically. For every size and fallback, see the App Store screenshot sizes reference.

Each slide is a stack of layers: background, device, text, shape and image. You can reorder, hide, duplicate or delete layers, and undo up to 50 steps. There are nine slide templates, including Headline top, Hero bottom, Two devices, Tilted device and Feature stack.

• Typography: eight font families (Inter, Poppins, Montserrat, Outfit, Plus Jakarta Sans, Space Grotesk, DM Sans, Playfair Display), weights from 400 to 800, alignment, line height, color, rotation and a drop shadow.
• Backgrounds: a solid color, a two-stop linear gradient at any angle, or an image.
• Per-locale text: each text layer can hold a different string for every language, so a German headline can wrap onto two lines while the English one stays on one.

A practical set of five iPhone slides might read: "Plan your week in one view", "Share lists with family", "Get reminders that adapt", "Works offline" and "Sync across devices". Each slide covers one benefit, and each headline is short enough to survive translation.

StoreLocale includes 17 frames across phone, tablet, laptop, desktop, TV and browser categories. For App Store work, the relevant ones are listed below. When you import an image, StoreLocale suggests a frame based on its aspect ratio, and you can wrap a screen in a frame or remove the frame later.

One export produces a single ZIP containing a PNG for every selected locale, size and slide. You can limit the export to chosen slides. Folders follow the pattern Platform / locale / size, and files are numbered in slide order so they upload in sequence.

The ZIP is named after the project, the number of locales and a timestamp, for example my-app_2locales_20260921_143000.zip. An option keeps original slide names without number prefixes. Locale folders use StoreLocale's short codes such as ja or zh, so map them to App Store Connect codes such as zh-Hans with the locale code guide.

Every export is rendered from one 1320 × 2868 portrait design and scaled to each size you select. The presets below keep almost the same proportions as the base. Upload each one to the Apple display slot that lists its pixel size, which isn't always the slot its name in the app suggests.

Apple recommends that apps offered in several languages localize their screenshots for each market (opens in a new tab). Headlines are live text layers you can edit per locale. The app screen inside the frame is an image, and that is where StoreLocale's AI steps in.

1. Text detection uses a vision model to find the UI strings in the screenshot, with their position, color and weight. It skips the status bar and icon-only controls. Detection and translation cost 0 credits.
2. Translation keeps brand names and tokens such as 4K, HD and PRO in the source language. You can edit any string before generating.
3. A generative image model repaints the screenshot with the translated strings in place. Standard costs 1 credit (1K output), Pro 2 credits (2K) and Ultra 4 credits (4K).
4. Media areas the model detects, such as video frames, posters and artwork, are masked and restored after the repaint, and rating and format badges are kept untranslated. Protection depends on detection, and failed generations refund their credits.

Because the repaint is generative, compare each result with the source in the split view before export. For right-to-left languages, read the RTL screenshot guide. For the difference between translating captions and translating the UI itself, see caption vs in-app UI localization.
