How to Localize App Store Screenshots (2026 Guide)

To localize App Store screenshots, design your English version once in Boom Screens, then click Localize — Claude AI translates every text layer into 80+ languages and exports native-resolution PNGs for all required device sizes in a single ZIP, ready to upload to App Store Connect.

Your screenshots are the single most important conversion asset on your App Store product page. Most users decide whether to download your app from the first two or three screenshots alone — before they ever read a word of your description. So when you expand into a new market and leave those screenshots in English, you are quietly leaving installs on the table.

This guide walks through how to localize your App Store and Google Play screenshots properly: what actually needs translating, the mistakes that make localized screenshots look amateur, and how to go from one English design to ten languages in minutes instead of days.

Why localized screenshots matter

Apple lets you upload a separate set of screenshots for every App Store storefront. Users in Japan, Germany, or Brazil see screenshots in their own language — if you provide them. Studies of app store conversion consistently show that localized store listings outperform English-only listings in non-English markets, often by a wide margin.

The markets where this matters most are also the highest-revenue ones: Japan, China, South Korea, Germany, and France all rank near the top of global App Store revenue, and all of them strongly prefer native-language listings.

What you actually need to translate

Localizing screenshots is not the same as translating your whole app. You only need to translate what appears on the screenshots themselves:

• Marketing captions — the headline text you overlay on each screenshot ("Track your fitness", "Send money in seconds").
• In-app text visible in the screenshot — if your screenshot shows a real app screen, the UI text in that screen ideally matches the target language too.
• Call-to-action labels — buttons or badges you have added as design elements.

You do not need to re-translate your app description here — that is a separate field in App Store Connect. Screenshots are purely the visual story.

The manual way (and why it hurts)

The traditional workflow looks like this:

1. 1Design your screenshots in English in Photoshop, Figma, or a screenshot tool.
2. 2Export the caption text and send it to a translator or paste it into Google Translate.
3. 3Manually swap each translated string back into each design, for each device size.
4. 4Fix every layout that breaks because German is 30% longer than English, or Arabic reads right-to-left.
5. 5Re-export every device size, for every language, with the correct file names.

For 5 screenshots × 10 languages × 3 device sizes, that is 150 individual exports to produce and name by hand. It is slow, error-prone, and the part everyone dreads.

The fast way: AI localization

Modern tools collapse that entire workflow. With Boom Screens, you design your screenshot once in English, then click "Localize" — and AI translates every text layer into all supported languages at once, preserving your layout and typography.

1. 1Design once in the visual editor with your English captions.
2. 2Click Localize — AI translates all text layers into 80+ languages in one pass.
3. 3Export the ZIP — every language × every device size, correctly named, at native resolution.

Right-to-left languages like Arabic are mirrored automatically, and CJK languages (Japanese, Korean, Chinese) render with bundled fonts so glyphs never break. What took a day now takes minutes.

Common localization mistakes to avoid

• Letting text overflow. German and Finnish run long. Always check that translated captions still fit the design — good tools auto-scale the font.
• Ignoring RTL languages. Arabic and Hebrew read right-to-left; a left-aligned layout looks broken to native readers.
• Using machine translation without review. Marketing copy needs nuance. AI translation is a huge head start, but have a native speaker review high-value markets.
• Forgetting to localize the in-screen content. A German caption over an English app screen feels half-finished.
• Wrong file names or sizes. App Store Connect rejects screenshots at the wrong resolution. Export at native size every time.

Conclusion

Localized screenshots are one of the highest-ROI changes you can make to your store listing — and they no longer require a designer and a week of work. Design your screenshots once, let AI handle the ten languages, and ship to every market with a listing that feels native.
