Hreflang Tag Generator & Validator

Hreflang Tag Generator & Validator

Proper hreflang tags help search engines serve the right language or region version of your pages. Manually writing them is error-prone and you can easily miss codes or duplicate entries. This tool lets you paste lines of URL|lang, instantly builds valid <link rel="alternate" hreflang="…"> tags, flags duplicates/missing codes, and lets you download your markup—100% client-side.

Output & Validation


  

How It Works

  • Paste each URL and its ISO lang code separated by “|” on its own line.
  • Click “Generate Tags” to parse, validate, and flag duplicates or missing codes.
  • Valid tags appear in the output box; errors appear above in red.
  • Click “Download Markup” to save as hreflang-tags.html.

FAQ

  • What codes are allowed? Any valid ISO-639-1 or ISO-639-1+region (e.g. “fr-CA”).
  • Duplicate URLs? Flagged as an error; only first occurrence kept.
  • Missing codes? Lines without “|” or empty lang produce an error.
  • Is data stored? No—everything runs in your browser; nothing is sent.
