Punycode / IDN Converter
Convert Unicode domain names (like 中文.com) to ASCII Punycode (xn--...). Useful for DNS, SSL, and debugging IDN-related issues.
Tip: Enter just the domain name (e.g., "中文.com"), not a full URL.
Punycode is used to represent Unicode characters in DNS hostnames. It starts with "xn--" followed by ASCII-safe encoding.
