Punycode Domain Converter

Enter an internationalized domain name that contains accented or non Latin characters and this tool converts it to its ASCII punycode form, the xn-- encoding that DNS actually uses, and it converts a punycode domain back to readable unicode. Domain names on the wire can only use a limited ASCII character set, so a name like a domain with an accented letter is encoded into punycode before it is looked up, and seeing both forms side by side helps you register, verify or debug international domains. It relies on the browser native URL parser to do the encoding, which is the same logic your address bar uses, so the result matches what really happens. This is also useful for spotting lookalike domains used in phishing. Everything runs locally in your browser, so the domain you enter is never sent to a server.
