Hreflang Tag Generator

The Hreflang Tag Generator is a free online tool that generate hreflang link tags, http link headers, and xml sitemap entries for multilingual and multi-regional websites with validation.. It runs entirely in your browser with no installation or sign-up needed.

They tell search engines which language and regional version of a page to show, helping international audiences land on the right localized content.

Yes. Google recommends an x-default hreflang pointing to a fallback page (language selector or primary language) for users whose locale does not match any variant.

In the HTML head, as HTTP Link response headers (for PDFs/non-HTML), or in the XML sitemap. This tool generates all three formats.

A bare code like "en" targets a language regardless of country, so any English speaker worldwide can match it. A code like "en-GB" combines the ISO 639-1 language (en) with an ISO 3166-1 Alpha-2 region (GB), targeting English speakers specifically in the United Kingdom. Use language-only codes when content is the same for everyone who reads that language, and add a region only when pricing, currency, spelling, or shipping genuinely differ by country. A common trap is reusing the same URL for both "en" and "en-US" with no real difference, which adds noise without benefit. This generator offers both forms in its dropdown of roughly 70 ISO options, so you can mix language-only and language-region rows and see the exact tags each produces before pasting them into your site.

"en-UK" is invalid because the region portion of hreflang uses ISO 3166-1 Alpha-2 country codes, and the official code for the United Kingdom is GB, not UK. The correct value is "en-GB". UK is only an informal abbreviation and a reserved exception in the standard, so search engines silently ignore a tag built with it, quietly breaking the whole language cluster. The same logic catches other slips, like writing a language code in the region slot. Because hreflang fails without any visible error, a single typo can go unnoticed for months. This tool validates every code you enter against the recognized ISO 639-1 and 3166-1 sets and flags anything outside them as a warning, so a mistake like "en-UK" surfaces immediately. Pick GB from the dropdown and the generator outputs the correct "en-GB" tag.

Yes. Hreflang must be bidirectional and self-referencing, which is the rule most implementations get wrong. If your English page lists a French alternate, the French page must list the English one in return; if the return link is missing, Google treats the annotation as unconfirmed and ignores it. On top of that, every page should include an hreflang link to itself, so a five-language cluster carries all five alternates on each page, self-link included. Miss any return reference and that pairing drops out silently. This generator's XML sitemap output handles the requirement for you by cross-referencing every alternate on every URL automatically, including each page's self-link, so the whole set stays reciprocal. For HTML and HTTP Link output, copy the matching tags onto each corresponding page. Load the sample set in the tool to see a fully reciprocal seven-language configuration.

At least two. Hreflang exists to connect equivalent pages across languages or regions, so a single page has nothing to point at and the annotation does nothing on its own. You need a minimum of two URLs, each mapped to a distinct, valid language or language-region code, before search engines have a relationship to act on. An x-default entry can sit alongside them as a fallback for visitors whose locale matches no version, but it does not replace having two real alternates. There is no practical upper limit, so large sites routinely run clusters of dozens of versions. This tool enforces the two-URL minimum as a hard validation error and warns when codes are duplicated or an x-default is missing, so an incomplete set never ships. Add your rows or use the bulk CSV import to map many language-URL pairs at once.

All three are equally valid to search engines, so the right choice depends on your stack rather than ranking impact. HTML link tags in the page head are the most common and the easiest to drop into a template, but they add weight to every page. The HTTP Link response header carries the same annotations in the server response and is the supported way to mark up non-HTML files such as PDFs. The XML sitemap method lists each URL with its full set of cross-referenced alternates, keeping the markup out of your pages entirely, which suits very large or frequently changing sites. Pick one method and apply it consistently rather than mixing them. This generator builds all three formats from the same set of rows at once, so you can compare them side by side and copy or download whichever fits your setup.
