Punycode Converter: Why ñ.com Shows Up as xn--nda.com

September 12, 2026

Domain names with accented letters do not travel over the internet as written. They get encoded into punycode, which is why the URL for a domain with ñ reads like a license plate rather than a word.

Convert Unicode domains to punycode and back using the built-in URL APIs. It is essential for registering international domains, checking what a suspicious link actually points to, and understanding why the good-looking URL in the status bar is not the one you recognize.

Try it now: open the free tool, runs 100{ddff9936f8333f09603555df7bd6492034f3a4a35de784276d3cf3d66166a113} in your browser.
