Google Chrome is probably the world’s most popular browser in terms of market share. That means different people, who speak various languages, use the browser. If you aren’t happy with the default language on Google Chrome (English) and you want to change it, you can change it on all platforms fairly easily.
Open System preferences and go to Language and Region. Click the + button under the left pane and add the language of your choice. You’ll see a prompt asking if you want to use this as your default language accept that. Now open Google Chrome and you’ll see that the UI has changed to the language of your choice. On Google Chrome for Mac, you can also quickly translate all websites to this language. Paste this in the address bar chrome://settings/?search=language and hit Enter. Add your favorite language, click the three vertical dots icon next to the language and tick the checkbox next to Offer to translate webpages to this language. This will allow you to quickly use Google Translate to change the language of any webpage to your choice.
