Punycode converter
Convert internationalized domain names.
Your input is processed by this site to return the result. Avoid entering sensitive information.
What does this tool do?
Punycode represents internationalized domain labels using ASCII-compatible characters, often beginning with xn--.
Why is it useful?
Conversion helps developers inspect internationalized domains and diagnose systems that only accept ASCII domain labels.
How to use it
- Enter a domain name without a URL or email address.
- Choose the conversion direction.
- Compare the result with your registrar or provider’s IDN handling.
What the result can and cannot tell you
Conversion does not establish that a domain exists, is safe or is owned by a particular person. The current implementation uses Python’s standard-library IDNA behavior; standards-policy validation remains pending.
