Punycode / IDN Converter
Convert an internationalized Unicode domain to its ASCII IDNA representation and decode valid Punycode back to Unicode. No DNS or website request is made.

Why domains use IDNA and Punycode
DNS was designed around an ASCII hostname format. Internationalized Domain Names let people use many Unicode characters, while IDNA converts each non-ASCII label to an ASCII-compatible form that commonly begins with xn--.
Conversion is not a DNS lookup
This tool changes representations only. It does not check whether a domain exists, who controls it, or what IP address it uses.
Look-alike awareness
Some characters from different writing systems can look similar. Browsers may display Punycode for names they consider visually ambiguous. Check the full domain carefully before entering credentials or sensitive information.
What this result means
The two values are alternate representations of the same IDN label under the platform codec. Conversion does not check registration, ownership, DNS existence or look-alike safety.
