Punycode Converter

About this tool

DNS only understands ASCII, so domains with accented letters, Chinese characters or emoji are stored in an ASCII form that starts with xn--. Convert in either direction to check what a domain really is or to configure DNS records.

Runs locally. Your URLs never leave your browser.
