How to use it
- Paste an opening html tag or copied page source into the checker.
- Review whether the html tag was found and whether the lang attribute looks practical.
- Copy the detected language code into QA notes or continue with hreflang and metadata checks.

3 focused answers for this page
Does this lang checker crawl my page?
No. It only checks pasted HTML in your browser and does not fetch live URLs, render pages, upload source, or store input.
Why does the html lang attribute matter?
The lang attribute helps browsers, assistive technology, translation tools, and search systems understand the document language.
Is this the same as hreflang validation?
No. The html lang attribute describes the current document language. Hreflang tags describe alternate language or regional URLs.
