Punycode / IDN Converter

An IDN (Internationalized Domain Name) lets domains use non-ASCII characters such as müller.de or café.fr. Punycode is how DNS stores them: the Unicode label becomes an ASCII string starting xn--. Convert either direction using the browser's built-in URL API.

Tool results are generated in English.

How it works

This tool uses the browser's native URL API ir URLSearchParams encoding, which implements the IDNA (Internationalized Domain Names in Applications) standard. All conversion happens locally in your browser. No data is sent anywhere.
