Hreflang Tags Generator
A hreflang tags generator turns a list of language and region versions of a page into the exact annotations search engines need to serve the right localized URL to the right user. Hreflang tells Google and Yandex that example.com/us/ and example.com/de/ are the same page in different languages, which prevents the localized versions from competing against each other and stops the wrong-language result from showing in a market where it will not convert.
This tool builds all three valid output formats — HTML <link> tags, an XML sitemap block, and an HTTP Link header — and validates the set as you type, flagging malformed codes, duplicate values, and a missing x-default. It is free and runs entirely in your browser, so nothing you paste is ever uploaded.
Add one row per localized URL. Pick a code from the list or type your own (ISO 639-1 language, optional ISO 3166-1 region, or x-default).
🔒 Private: everything runs in your browser. Nothing you paste is uploaded.
How to use the hreflang tags generator
Add one row for every localized URL, choose a language-region code, and copy the format that matches where you implement hreflang — the page head, your sitemap, or the server response header.
Use the correct code: language, optional region, and x-default
The hreflang value is an ISO 639-1 language code, optionally followed by an ISO 3166-1 Alpha-2 region code, written as language or language-REGION. Use en to target English speakers anywhere, or en-GB and en-US to split British and American audiences. The region never stands alone — de-DE is valid, DE is not. Always add one x-default row pointing at the fallback page, usually a language selector or your primary global version, which search engines serve to users whose language and region match none of your listed alternates.
Make every annotation reciprocal and self-referencing
Hreflang only works when the references point both ways. If the German page links to the English page as an alternate, the English page must link back to the German page, or search engines ignore the annotation entirely. Each page in the set must also list itself as one of the alternates. That is why the XML and HTTP outputs here repeat the full set on every URL: copy the complete block to each page rather than giving each language only its own line. A one-way or self-missing reference is the single most common reason a hreflang implementation silently fails.
Pick the implementation method that fits your stack
All three formats are equivalent to search engines, so choose by what you can edit. HTML <link> tags go in the <head> of every page and suit most CMS templates. The XML sitemap method keeps markup out of the page and scales well for large sites, but every URL block must list the entire alternate set. The HTTP Link header is the only option for non-HTML files such as PDFs, set at the server or CDN level. Never mix methods for the same set of pages — pick one and apply it consistently across the whole language group.
Hreflang tags generator frequently asked questions
Q1What is the difference between hreflang and the lang attribute?
The HTML lang attribute on the html element declares the language of a single document for browsers and screen readers. Hreflang is a separate annotation that tells search engines a page has equivalent versions at other URLs, so they can serve the right one by language and region. They serve different jobs: lang describes one page, hreflang maps the relationship between several. A multilingual site needs both, and they should agree.
Q2Do I really need an x-default tag?
It is strongly recommended rather than strictly required. The x-default value tells search engines which page to serve users whose language and region do not match any of your listed alternates, such as a French speaker visiting a site that only offers English and German. Without it, search engines guess, often serving a market-specific page to the wrong audience. Point x-default at a language selector or your primary global version, and the tool warns when the row is missing.
Q3Where should I place the hreflang tags?
Choose one of three locations and apply it consistently. HTML link tags belong in the head section of every page in the set. The XML sitemap method places xhtml:link entries inside each url block, keeping the page markup clean. The HTTP Link header is set in the server response and is the only method that works for non-HTML files like PDFs. Do not combine methods for the same pages, because conflicting signals can cause search engines to ignore the annotation.
Q4Why is my hreflang implementation being ignored?
The most frequent cause is missing reciprocity: if page A points to page B as an alternate but page B does not point back, search engines discard the link. Other common faults are relative instead of absolute URLs, pages that are blocked by robots or carry a noindex tag, malformed codes like a bare region, and a page that fails to reference itself. Validate that every page returns the full, identical set of alternate URLs.
Q5Does this hreflang generator send my URLs anywhere?
No. Every code check and every output format is built in your browser with client-side JavaScript. The language codes and URLs you enter are never uploaded, logged, or stored on any server, and the tool keeps working offline once the page has loaded. That makes it safe to use for staging environments, unpublished pages, or any internal URLs you would rather not share with a third-party service.
