Best Translation Tools for Chrome

Updated October 2026

How to choose a translation extension

The first seven picks can be installed for free, though DeepL, Immersive Translate, Mate Translate and OpenL Translate also sell paid plans, and their free use has limits. Read Frog is open source, and with an AI provider you bring your own API key, which may cost you. XTranslate works after install with Google Translate or Bing, and needs your own API key for AI providers. KISS Translator and Yomitan are open source (both GPL-3.0). Yomitan is a dictionary for learners and ships with no dictionaries, so you import them. The real differences are what they translate and how they show the result.

• Selected text or the whole page. Google Translate, DeepL, Mate Translate and Simple Translate focus on highlighted words and phrases (DeepL's full-page translation needs Pro). Mate Translate says it also translates web pages. TWP - Translate Web Pages and OpenL Translate translate the entire page. Read Frog does both: it translates pages and has a toolbar for text you select. XTranslate also does both: it translates words and selections, and full pages from the context menu or action window. KISS Translator translates whole pages, selected text, input boxes and YouTube subtitles. Yomitan is not a page translator: it is a pop-up dictionary for learners.
• Side-by-side view. Immersive Translate keeps the original text visible next to the translation instead of replacing it. Read Frog also offers a bilingual view, plus a translation-only view. KISS Translator shows the translation beside the original text as well.
• Translation quality. We cannot rank accuracy, because it depends on your text and language pair. DeepL is a dedicated translation service and a good first test. Try the same passage in two tools.
• Engine choice. TWP lets you switch between Google, Bing and Yandex. Simple Translate works with Google Translate or the DeepL API. Read Frog works with 20+ AI providers, plus Google Translate, Microsoft Translate and DeepLX. XTranslate works with Google Translate and Bing after install, and with OpenAI, Gemini, Grok and DeepSeek if you add your own API key. KISS Translator lists Google, Microsoft, Tencent, Volcengine, DeepL, Azure AI and Cloudflare AI, plus AI models such as OpenAI, Gemini, Claude, Ollama, DeepSeek and OpenRouter, and Chrome's built-in AI translation.
• Other formats. TWP and Immersive Translate also handle PDFs. Immersive Translate covers video subtitles, and OpenL Translate translates text in images.

Our picks at a glance

Which is the best translation extension for Chrome?

For most people, Google Translate is the best starting point. It is free, comes from the Google Translate team, and shows a popup translation of the text you highlight. Chrome already translates full pages natively, so this extension covers quick lookups while you read. If you want a dedicated translation service, try DeepL and compare both on your own text.

How do I translate a whole page in Chrome with an extension?

Install TWP - Translate Web Pages and click its button to translate the entire page in place. You can pick Google, Bing or Yandex as the engine in its settings, and it also handles PDF documents through its own viewer. OpenL Translate is another option that translates full webpages, and Chrome’s own built-in translate bar needs no extension at all.

TWP sends the page text to the engine you pick, so skip pages that show sensitive details.

Which translation extension is the most accurate?

We cannot rank accuracy, because it depends on your text and language pair. DeepL is a dedicated translation service and a good first test. Its extension translates selected text on the free tier, and full-page translation needs Pro. Run the same passage through two tools, and skip sensitive text, since it goes to the service.

Can I see the original text and the translation side by side?

Yes. Immersive Translate is built for this. It translates whole webpages with the original text kept visible alongside, and applies the same bilingual view to PDFs and video subtitles. You can use it free, with a daily limit. KISS Translator is an open-source alternative that shows the translation beside the original on any page.

Which extension helps me learn a language while I read?

Yomitan. It shows a pop-up dictionary definition as you read, with pronunciation audio, stroke-order diagrams for kanji and Anki flashcards through AnkiConnect. It started with Japanese and now supports many languages. It ships with no dictionaries, so you import the ones you want. It is open source under GPL-3.0. For whole-page translation, use KISS Translator.

Which extension works best as a dictionary while browsing?

Mate Translate combines a translator, a dictionary and a phrasebook. Select text or double-click, and a translation appears. You can look up word meanings as well as translations. Mate's own privacy policy says it collects the URLs you visit, so read it before you install, and avoid it on pages with private links.

Can I choose between Google Translate and DeepL?

Yes, with Simple Translate. It supports Google Translate and the DeepL API, and it translates selected or typed text without leaving the page. The text you translate goes to the service you pick. It is free to install and open source under MPL-2.0. We did not check what the DeepL API costs.

Can I translate with my own AI provider?

Yes, with Read Frog. It supports 20+ providers, including OpenAI, Anthropic, Google Gemini and Ollama; you add your own endpoint and API key. The provider may charge you. Your page text goes to the provider you pick, and in context-aware mode also the page title and a Markdown version. It is open source under GPLv3. Read its privacy policy first.

Which translator lets me choose between Google, Bing and AI providers?

XTranslate. Google Translate and Bing work after install. OpenAI, Gemini, Grok and DeepSeek need your own API key, per the README. It is an online tool, so you need a connection, and the text you translate goes to the engine you pick. We could not read the developer’s privacy policy when we checked; read it before installing.
