How it works
Recent versions of Chrome on Windows, macOS, Linux and ChromeOS include an on-device translator. This page asks it to translate your text one paragraph at a time, so your layout is kept. The first time you use a language pair, the browser downloads a small language pack, and after that it works offline.
Which browsers can translate here
Right now the built-in translator is in desktop Chrome 138 and newer, and in some preview versions of other browsers. On phones and in browsers without it, this page tells you so instead of sending your text to an online service. If you need a translation there, use a translator you trust with the content.
Why translate on your device
Online translators receive every word you paste. That is a poor fit for contracts, medical letters, HR messages and private conversations. With on-device translation, the text stays on your computer from start to finish.
Questions
How good are the translations?
They are good for understanding and for everyday messages. For legal, medical or published text, have a fluent speaker check the result.
Can it detect the language?
Yes, when your browser also has its built-in language detector. Otherwise, choose the language you are translating from.
