Why it's a strong pick

Immersive Translate shows the original and the translation together, so you can check the translation against the source as you read. It covers web pages, PDFs and video subtitles in one extension. The trade-offs: the free plan has a daily limit, and your text goes to the translation engine you choose.

What it does

The store listing is titled "Immersive Translate: AI Web, PDF & Video Translator". For websites, it translates in a bilingual layout and identifies the main content area of the page. It also handles PDF files and video subtitles. Its pricing page says image translation is free. You pick the translation engine, so the quality and the privacy depend partly on which engine you choose.

Key features

Bilingual website translation. The original text and the translation sit together on the page.
Main content detection. The store listing says it identifies the main content area of a page.
PDF translation. The same bilingual approach works on PDF documents.
Video subtitle translation. It translates subtitles on supported video sites.
Image translation. Immersive Translate's pricing page says this is free.
Your choice of engine. The privacy doc says translation content is only sent to the engine you select.

Who it's for

This extension suits people who read long pages in a second language, such as news, research papers or documentation, and want the source text in view. It also fits language learners who like seeing both versions together. If you only look up short snippets, Google Translate is simpler. If you want a lighter page translator, see TWP, and for another all-in-one option, see OpenL Translate.

Is Immersive Translate free?

You can use it for free. Its pricing page says daily translation requests are subject to a reasonable limit, with a higher quota after registration. It also lists a Pro plan with higher limits and premium engines, and says batch translation needs a login. Limits and plans change, so check the current quotas on its pricing page.

Do you have to sign in?

Not strictly. The vendor says free use is available and that registering raises your daily quota. So signing in is optional, but it can matter if you hit the free limit. Batch translation is the exception, which its pricing page says needs a login. Check current quotas before you rely on it for heavy daily use.

Where does your text go?

Immersive Translate's privacy doc says translation content is only sent to the translation engine you select. It also says it collects pseudonymised usage statistics and does not store user translation logs. For uploaded files, the doc says files are stored temporarily and deleted after the service. Those are the vendor's words, so read the policy.

What permissions does it ask for?

We could not find a published permission list. An extension that translates whole pages usually needs to read and change the pages you use it on. Check the install prompt for the current list before you install, since permissions can change between releases.

FAQ

Does it translate PDFs? Yes. The store listing and the vendor describe PDF translation. Uploaded files follow a separate file policy, which the privacy doc describes.

Can I choose the engine? Yes. The privacy doc says content goes only to the engine you select. Read that engine's own policy too.

Does it translate video subtitles? Yes, per its store listing, on supported video sites.

Good to know

The engine you pick receives your text, so check that engine's policy, not just Immersive Translate's. Do not translate sensitive text, such as legal, medical or financial details, unless you have read the policy. Uploading a PDF follows a different rule, since files are stored temporarily. If you hit the free daily limit, check its pricing page for the current quotas.
