日本語First, work out which case you are in
Searches for "edge translation failure", "edge cannot translate this page" and "edge cannot translate" actually cover several different problems. Match your case in the table, then start from that section:
| Symptom | Common cause | Try first |
|---|---|---|
| Translation fails / "Cannot translate this page" | Bing Translator temporarily unavailable, network or proxy blocked, or the page is unsupported | Step 1 refresh / InPrivate → Step 2 network and service |
| Translate button missing / icon never appears | "Use Microsoft Translator services" is off, the icon is hidden, or an organization policy or extension disables it | Step 3 language settings → Step 4 policy and extensions |
| Most pages translate, a few do not | The page needs a sign-in, embeds a PDF, or loads content dynamically so no language is detected | Step 5 the page itself → finally the extension as a fallback |
Why Edge translation fails so often
Edge web translation uses the Bing Translator (Microsoft Translator) online service, so your machine must be able to reach the relevant domains, and translation must be switched on in the language settings: "Use Microsoft Translator services". That is why "edge translation failure" usually comes down to one of three causes:
- Service or network problem: Bing Translator is temporarily unavailable, or a proxy / VPN / firewall blocks the connection.
- Setting is off: "Use Microsoft Translator services" is disabled in edge://settings/languages, so no translation entry point appears.
- Policy or extension conflict: an organization group policy disables translation, or an extension intercepts it.
Step 1: for a failed translation or "Cannot translate this page", try these first (about 5 minutes)
- Reload the page and try again: Bing Translator occasionally wobbles — just press
F5orCtrl + Rretry, and if neededCtrl + F5a hard refresh (reloading past the cache). Most temporary failures recover. - Open the same page in an InPrivate window: press
Ctrl + Shift + Nto open a new InPrivate window and visit again. If translation works in InPrivate but not in a normal window, it is an extension or cache conflict, so jump to step 4 and check extensions. - Test another foreign-language page: if only the current page fails and other pages translate, the problem is probably that page (see step 5), not Edge.
- Turn off the proxy or VPN and retry: a wrong system proxy or VPN prevents Edge from reaching Bing Translator; if you must use a proxy, check that the routing rules allow the Microsoft Translator domains, or switch to global mode and try again. Exit it first, then retry.
- Clear cache and site data: Settings → Privacy, search and services → Clear browsing data, set the time range to "All time", tick "Cached images and files" and "Cookies and other site data", then reload the page.
If none of that works, continue with the network and service checks in the next step.
Step 2: check whether Bing Translator is reachable
- Open the Bing Translator web page directly: visit Bing Translator in the browser and translate a paragraph of English. If that also fails, Bing Translator is unreachable right now — a server-side or network problem — so wait a while and retry.
- Check the firewall and security software: make sure Edge is not being blocked from making outbound connections.
- Restart Edge or the computer: network sessions can go stale after a long sleep and make translation fail; restart and retry.
- Change DNS: if the Bing Translator page will not open either, DNS probably cannot resolve the Microsoft Translator servers. Switch the computer to a public DNS and retry: Alibaba
223.5.5.5or Tencent119.29.29.29, or4.2.2.2/8.8.8.8(Settings → Network & Internet → adapter → DNS server assignment).
Step 3: translate button missing? Check the language settings first
Another common form of "edge cannot translate" is that no translate icon appears in the address bar at all. In that case check the language settings first:
- Type
edge://settings/languagesin the address bar and press Enter. - Confirm that "Use Microsoft Translator services" is on (the switch sits under "Languages"). While it is off, Edge will not offer translation.
- Check the "Never translate these languages" list: if the target language was added to this block list by mistake, Edge skips translation entirely. Remove it and reload the page.
- Move "Chinese (Simplified)" to the top of the language list and confirm the target language is correct.
- After switching it on, reload the foreign-language page; a "Translate" icon should appear at the right of the address bar. If it still does not, try the "Translate" button at the right of the address bar, or right-click the page → "Translate selection".
- Set the source language manually: if Edge says it cannot translate but the page is clearly foreign, click the translate icon in the address bar and change the source language in the panel from "Detected language" to the real one (English, for example), then click "Translate". When language detection or the page's language tag is wrong, this step usually fixes it.

Step 4: organization policy and extension conflicts
On a work computer, or one with many extensions installed, translation may be disabled by a policy or an extension:
- Check organization policy: type
edge://policyin the address bar and look for translation-related policies (such as TranslateEnabled). If the machine is managed centrally, ask IT. - Disable suspicious extensions: open
edge://extensions, then temporarily disable translation and ad-blocking extensions one by one (such as uBlock Origin, AdGuard), reloading a foreign-language page after each to find the culprit. Ad blockers sometimes kill the endpoint that translation uses.
Step 5: one page will not translate? Check whether the page itself is the problem
"Edge cannot translate this page" can also mean the page is unsupported — nothing to do with Edge:
- Pages that need a sign-in: pages whose content only appears after signing in sometimes cannot be translated; sign in first, then retry.
- Embedded PDFs and special documents: some PDF viewer windows cannot be handled by web translation; download the PDF and translate it in Word / WPS, or use a web translation extension.
- Dynamically loaded content: when the page loads its content asynchronously with scripts, translation may not capture the full text; wait for the page to finish loading, then translate.
- A language tag that does not match the content: when the language tag in the page code (such as the
langtag) says Chinese but the body is English, Edge assumes "the page is already in your preferred language" and refuses to translate. Fix it by setting the source language manually in the address-bar translation panel (see step 3, item 6). - Body text inside an iframe, Canvas or image: built-in translation can only extract text nodes from the page; text inside third-party frames, canvases or images is invisible to it, so such pages need a web translation extension (which handles more nodes) or manual copy-and-paste.
- Pages with scraping or copyright protection: some finance, academic or intranet pages restrict scripts from reading the body, so built-in translation has nothing to work with.
- The page is Chinese, or the language was detected wrongly: a wrong target language also produces "cannot translate"; check the language list.
When Edge translation fails, fall back to a bilingual web translation extension
If you have tried all of the above and Edge built-in translation still fails, you can install the TopCopilot web translation extension (works in Edge and Chrome, available on Microsoft Edge Add-ons):
- Translations below the original: after translating the page you get a bilingual view with original and translation aligned paragraph by paragraph, easy to check.
- Several switchable engines: Bing, Google, built-in browser AI and LLM models — use whichever works.
- Selected-text translation + word dictionary: select a word or sentence to see its translation, with English grammar analysis, which suits reading foreign-language material.
After installing, open a foreign-language page and click the extension icon to translate the whole page; you can also search for "TopCopilot AI Translation Assistant" on Edge Add-ons.
FAQ
What does "cannot translate this page" in Edge mean?
Edge built-in translation relies on the Bing Translator (Microsoft Translator) online service. "Cannot translate this page" usually means the service is temporarily unavailable, the network or proxy is blocked, or the page itself is unsupported (some PDFs, pages that need a sign-in). Refresh and retry, then check the proxy and firewall; if that fails, try again later or switch to a web translation extension.
Why does Edge keep saying it cannot translate one particular page?
Two common causes. First, the language tag (lang) in the page code does not match the content, so Edge thinks the page is already in your preferred language and refuses to translate: click the translate icon in the address bar and change the source language in the panel from "Detected language" to the real one. Second, the body text sits inside an iframe, Canvas or image, where built-in translation cannot extract text; such pages need a web translation extension or manual copy-and-paste.
What if the Edge translate button is missing?
Open edge://settings/languages and confirm "Use Microsoft Translator services" is on, then check whether the translate icon in the address bar has been hidden. If it is still missing, check edge://policy for an organization policy that disables translation, or open edge://extensions and temporarily disable translation and ad-blocking extensions to test.
Is Edge translation failure the same problem as Chrome, Word or Excel translation failure?
Not exactly. Edge built-in translation relies on Bing Translator, Chrome built-in translation relies on Google Translate, and Word / Excel built-in translation relies on Microsoft Translator services. Each uses its own service, so on one machine one may work while another does not; troubleshoot them separately.
Is there another way when Edge web translation fails?
You can copy the URL into the Bing Translator web page (Bing online translation), or install the TopCopilot web translation extension: translations appear below the original as a bilingual view, with four engines — Bing / Google / built-in browser AI / LLM.
