Free Punycode Converter (International Domains)

Punycode allows domain names to contain non-ASCII characters (like Chinese, Arabic, or accented letters) by converting them to ASCII format that works with the existing DNS system.

The "xn--" prefix indicates that the domain label is Punycode-encoded and contains international characters. Browsers automatically decode xn-- domains to display the original Unicode.

Homograph attacks use look-alike characters from different scripts to create deceptive domain names. For example, using Cyrillic "а" instead of Latin "a" to fake popular domains. Always verify URLs carefully.

No, only certain Unicode characters are allowed in domain names. Characters must come from approved scripts, and some characters (like emoji in most TLDs) are restricted. Rules vary by registrar and TLD.

No, modern browsers handle conversion automatically. You can type international domains directly (like "münchen.de") and the browser converts them to Punycode for DNS lookup.

Many browsers now show Punycode for mixed-script domains or domains with suspicious characters. You can also check the actual URL in the address bar and use bookmarks for sensitive sites.
