Best App Screenshot Localization Tools (2026)
Short answer: For the widest language coverage, AppScreens (80+ languages) and Screenshot Studio (AI translation into any language) lead. Screenshot Bro covers 30 presets plus custom codes with on-device translation and per-shape overrides. Fastlane frameit localizes from .strings files if you already have translations.
Localizing screenshots is where a store listing gets expensive: the same design, ten times, with copy nobody on the team can proofread. This roundup compares the best app screenshot localization tools on the parts that actually matter — language coverage, whether translation is built in, how per-locale edits work, and whether the tool uploads the result.
Details were checked in August 2026 against each tool's own site and documentation; pricing and features change, so verify before deciding.
What To Look For
- Coverage: how many locales are preset, and can you add your own codes?
- Translation: built in, or do you paste in strings from elsewhere?
- Overrides: can one locale differ without duplicating the design?
- Export shape: are files organized per locale in a form App Store Connect accepts?
The Options
AppScreens — widest language list
A browser tool advertising localization and caption translation into 80+ languages on paid plans, along with automatic store upload and support for several storefronts. Its free plan is limited (5 screenshots, 1 saved project) and shows a watermark in the designer once Pro features are used. The most sensible pick if you ship into more markets than any preset list covers. See the AppScreens comparison.
Screenshot Studio — AI translation, any language
A native Mac and iOS app with built-in AI translation that needs no API key, per-locale review and editing, and direct App Store Connect upload in the right order for every platform and locale. All features are free to try, with payment required to export. See the Screenshot Studio comparison.
Screenshot Bro — 30 presets, on-device, override anything
A native Mac and iPad app with 30 language presets plus custom locale codes. Auto-translate fills missing copy on-device, translation progress is tracked per locale, and any shape can carry a per-locale override for text, position, size, or image — so a long German headline moves without forking the design. Exports land in locale folders App Store Connect picks up directly, and Pro uploads them for you. Localization is available on the free tier too.
Screenshots Pro — auto-translate plus an API
A browser tool that auto-translates into store-supported languages on its paid plans, with a REST API on the top tier for regenerating localized sets from CI. See the Screenshots Pro comparison.
Fastlane frameit — free, if you already have the strings
Open source and free: put a title per locale in .strings files and frameit renders framed, localized screenshots, which fastlane deliver then uploads. No translation is included — you supply it — and design control is limited. Details in Fastlane snapshot vs Screenshot Bro.

The Short Version
More than 30 markets: AppScreens or Screenshot Studio. A normal multi-market listing on a Mac, with overrides and no watermark: Screenshot Bro. Screenshots generated by a pipeline: Screenshots Pro or Fastlane. Whichever you pick, read what breaks in Japanese, Chinese, and German before you translate — layout, not vocabulary, is what usually fails.

FAQ
What is the best tool for localizing App Store screenshots?
It depends on how many markets you ship to. AppScreens advertises 80+ languages on paid plans and Screenshot Studio translates into any language with built-in AI, so both suit very wide rollouts. Screenshot Bro covers 30 language presets plus custom locale codes with on-device auto-translate and per-shape overrides, which fits most listings. If you already have translated strings, Fastlane frameit renders them for free.
Do I need to translate App Store screenshots at all?
Not for every market, but screenshot text is the first thing a browsing user reads, and Apple shows localized listings by device language. Translating the three or four headline phrases for your biggest non-English markets is usually the highest-return localization work you can do — far cheaper than translating the app itself.
What does per-locale override mean?
It means changing one element for one language without duplicating the whole design: a shorter German headline, a repositioned label for Japanese, or a different in-app screenshot for a market with different content. Layout, colours, and images stay shared, so a design fix applies everywhere at once.
