hreflang Tag Generator

The hreflang Tag Generator is a browser-based tool that lets you easily create hreflang tags required for multilingual and multi-regional websites through a simple form interface. The hreflang attribute is used in HTML link elements and XML sitemaps to inform search engines about the language and regional targeting of a page, enabling precise international SEO control.

Properly configured hreflang tags help search engines like Google index each language and regional version of a page correctly and display the right version in search results based on the user's language and location preferences. Misconfigured hreflang tags can result in the wrong language version appearing in search results, poor user experience, or pages being flagged as duplicate content, negatively impacting international SEO performance.

This tool lets you select language-region codes (ja, en, en-US, en-GB, zh-Hans, zh-Hant, ko, fr, de, es, etc.) from a comprehensive dropdown menu and enter the corresponding URL to automatically generate hreflang tags in seconds. Output is available in two formats: HTML link tags (link rel="alternate" hreflang="...") and XML sitemap format (xhtml:link), which can be toggled between and copied from separate tabs with one click.

Practical features include an x-default add button for fallback content, dynamic row addition and removal, and comprehensive validation (warnings for missing x-default, duplicate language code detection, and URL format verification). SEO specialists, web developers, and multilingual site operators can use this tool to efficiently generate accurate hreflang tags and optimize their international SEO strategy. All processing is done entirely in the browser — no input data is ever sent to any server.
