How to translate a web page in Opera

Opera doesn't translate pages on its own. Mate's Opera extension does, between 200+ languages, and it also translates single words and sentences without leaving the page.

Install the extension

Get Mate from Opera add-ons.

Translate the whole page

1. Open a page in a foreign language. A small Mate bar appears in the top-right corner: "This page is in Spanish".
2. Click Translate to English (or your target language).
3. Click Switch back to Spanish in the bar to see the original again.

No bar? Right-click the page and choose Open full page translation.

Tick Always translate Spanish to English to have Mate translate such pages on its own (a Mate Pro feature). Tick Never translate Spanish or Never translate example.com to stop the bar from showing up for that language or site.

Page translation is switched off on a few sites that don't survive having their text replaced, for example Google, YouTube, Facebook, X, Notion and GitHub. Selected-text translation works everywhere.

Translate a word or a sentence

Select the text and click the floating Mate button, or press Shift+T. The translation appears in a tooltip next to the selection. All the options are described in Translate selected text on any web page.

Change the target language

Click the Mate icon next to the address bar and pick the language in the popup.

Opera limits

Opera's PDF viewer is closed to extensions, so selected text in PDFs can't be translated in Opera. Use Mate for Mac or the Chrome extension for PDFs.
