Upwork (app localization and website translation jobs from startups expanding globally), ProZ (localization projects from established companies through a professional marketplace), LinkedIn (pitch startup founders announcing international launches who need localization support).
Apps and websites expanding to new countries need every button, menu, error message, and onboarding screen translated — plus adaptation of date formats, currencies, and cultural references. You translate the strings file (the text behind every UI element) into your native language. Charge $0.05-0.10 per word or $200-600 per project. App localization is more technical than document translation and pays better.
🚀 First Step
Export the English UI strings from any open-source app on GitHub, translate 50 common UI strings into your second language, and organize them in a spreadsheet.
  • Learn how to work with .json, .xml, and .strings resource files — these are the formats developers use for app localization.
  • Keep translations 30% shorter than English for UI elements — German, Spanish, and French text expands and breaks button layouts.
  • Provide a 'context note' column in your deliverables explaining ambiguous strings (like 'Save' which could mean preserve or salvage).
