Top Picks

Best Overall: Google Translate (Built-in Chrome)

  • Automatic language detection
  • Full-page translation preserving layout
  • 130+ languages
  • Works on virtually every website

  • Limited customization
  • No selected-text popup in the built-in version (available via the extension)

Best Quality (European Languages): DeepL Extension

DeepL’s browser extension offers the highest translation quality for its supported languages. The selected-text popup is particularly well-designed.

Strengths:

  • Text-to-speech

Limitations:

  • Translation quality depends on the engine used
  • Not free (though reasonably priced)

Feature Comparison

  • Best: Google (built-in) and DeepL (Pro) — preserve layout well
  • Good: Microsoft Translator, TWP
  • Acceptable: Mate, ImTranslator

Selected Text Translation

Highlight text and get a popup translation:

  • Best: DeepL — clean popup with alternatives and pronunciation

Privacy Considerations

All browser translation extensions send your browsing content to external servers for translation. Consider:

  1. What data is sent: The text content of web pages or selected text
  2. Who processes it: Google, DeepL, Microsoft, or Yandex
  3. Data retention: Check each provider’s privacy policy
  4. Sensitive content: Do not rely on browser translation for confidential documents — use a private solution instead
