Hreflang Tag Generator

Generate valid hreflang tags for multilingual and multiregional pages, with x-default and language-region code validation.

100% Browser-Based • Local Processing

Every version of this page

One row per language or language-region version, including the page you are starting from. The set has to list every version and itself — a cluster that leaves one out is ignored.

x-default

Where someone lands when none of your versions match their language or region. Usually a language selector, or whichever version you would rather a stranger saw. Optional, and Google recommends it.

Tags

The same complete block goes on every page in the set. Not a tailored block per page — the identical list, including each page’s link to itself. If the Spanish page does not link back to the English one, Google drops the pair, and one missing return link can unpick the whole cluster. Hreflang also only decides which version to show someone; it is not a ranking signal and it does not resolve duplicate content, so each version still needs a canonical pointing at itself.

HTML — in the <head> of every version

HTTP headers — for PDFs and other non-HTML files

XML sitemap — declared once, not per page

The sitemap route is usually the easier one to keep correct at scale: the reciprocity lives in one file you generate, instead of in tags spread across every template. Pick one of these three methods — mixing them is allowed but gives you three places for the same fact to drift.

Two things no client-side tool can verify: that each URL actually returns 200 and is indexable, and that every one of those pages really carries the block back. After deploying, spot-check one non-default version in Search Console’s URL Inspection — a cluster that looks perfect in the markup can still be broken by a redirect in the middle of it.

Overview

What is a Hreflang Tag Generator?

A Hreflang Tag Generator creates the hreflang link tags that tell search engines which language and region version of a page to show to which users. You list each language-region and its URL, and it outputs valid tags — with an x-default for unmatched users — to add to all your translated or regional pages so the right version appears in the right country's results.

If your site has pages in multiple languages or for different regions, hreflang tags tell search engines which version to serve to which audience — Spanish to Spanish speakers, the UK page to UK searchers. Done wrong (invalid codes, missing return tags), Google simply ignores them.

This generator builds valid hreflang tags from your list, checks the language and region codes, and adds an x-default. It runs entirely in your browser, and the tags are yours to paste into each page's <head>.

How to generate hreflang tags

Step 1: Add a row for each version: its language (and optional region) plus the full URL

Details

Hreflang done right — reciprocity and codes

Hreflang uses link tags like <link rel="alternate" hreflang="es-ES" href="..."> to map each page to a language (and optionally a region). The language is an ISO 639-1 code (en, es, fr) and the optional region is an ISO 3166-1 Alpha-2 code (US, GB, MX), joined with a hyphen — getting these wrong is the most common reason Google ignores hreflang, so the generator validates them. Two rules are essential: the set must be reciprocal — every version must list every other version including itself (self-referencing), or the cluster breaks — and the URLs must be absolute. Add an x-default entry pointing to a fallback (often your main or language-selector page) for users whose language/region doesn't match any version. Note that hreflang signals which version to show, not which to rank; it doesn't fix duplicate content (pair it with self-referencing canonicals on each version). You can also implement hreflang in the XML sitemap or HTTP headers instead of tags. Everything is generated locally in your browser. For canonical handling, use the Canonical Tag Generator.

Frequently Asked Questions

What is hreflang and when do I need it?

Hreflang is a set of link tags that tell search engines which language or regional version of a page to show to which users. You need it when you have the same content in multiple languages, or region-specific versions (e.g. en-US and en-GB), so the right version appears for each audience instead of the wrong one ranking.

What's the correct hreflang code format?

A language code from ISO 639-1 (en, es, de), optionally followed by a hyphen and a region code from ISO 3166-1 Alpha-2 in uppercase (en-GB, es-MX, pt-BR). Use language alone (es) to target speakers anywhere, or language-region (es-MX) for a specific country. Invalid codes are the top cause of hreflang being ignored.

What does x-default do?

x-default specifies the fallback page for users whose language or region doesn't match any of your listed versions — for example a global homepage or a language-selector page. It's recommended whenever you have multiple versions, so unmatched visitors are sent somewhere sensible rather than to an arbitrary version.

Why does hreflang need to be reciprocal?

Because search engines treat the versions as a confirmed cluster only if they agree. Every version must list every other version, and itself (self-referencing). If page A points to B but B doesn't point back to A, Google may ignore the whole set. The generator helps you produce the complete set to place on every page.

Does hreflang replace canonical tags?

No — they do different jobs and should work together. Hreflang says which language/region version to show; canonical says which URL is the master for duplicate content. Each version should have a self-referencing canonical (pointing to itself), not a canonical pointing to another language — that would tell Google to ignore the alternates.

Where do I put hreflang tags?

In the <head> of each page (the same complete set on every version), or alternatively in your XML sitemap or via HTTP headers for non-HTML files. Tags in the head are the most common approach. Whichever method you choose, apply it consistently and don't mix conflicting implementations.

Is it free, and do I need to sign up?

Yes, it's completely free with no account, no trial, and no limit on how many times you use it. Unlike most SEO suites, there's no login wall — it runs entirely in your browser, so you just open the page and use it.

Is my data private?

Yes. Everything is processed in your browser — whatever you type or paste is never sent to a server. Nothing is stored once you close the tab, so your URLs, content, and site details stay on your own device. That client-side approach is the core difference from cloud SEO tools.

Does it work on mobile?

Yes. It runs in your phone's browser with nothing to install, so you can generate or check markup on Android or iOS. The layout adapts to small screens, though pasting longer code is easier on a desktop.

Does it work offline?

Once the page has loaded, the work runs entirely on your device, so it keeps working without a connection. You only need to be online to open the page the first time — which is also why nothing you enter is uploaded.

Can I copy the output?

Yes. You can copy the generated code or results to your clipboard with one click, ready to paste straight into your site's HTML, CMS, or files. Because everything runs locally, copying is instant with no upload step.

Will this directly improve my rankings or get me into AI answers?

It produces correct, standards-compliant markup that helps search engines and AI engines (Google, AI Overviews, ChatGPT, Perplexity) understand your page clearly — which is a prerequisite for ranking and being cited. But it doesn't directly change rankings or guarantee a rich result or AI citation; those are decided by the engines based on your overall content and authority.
