IDN Converter

Internationalized domain names allow national characters, including Cyrillic and accented letters, to appear in web addresses. DNS itself uses an ASCII-compatible representation called Punycode, usually beginning with xn--. Converting between the readable IDN form and Punycode is important when configuring DNS, certificates, redirects, email systems, analytics filters, and server rules.

Enter a domain or label to convert it in either direction and copy the normalized result. The tool helps detect typing differences and makes technical configuration easier, but visually similar Unicode characters can belong to different alphabets. For security-sensitive use, verify the intended spelling and registrable domain instead of relying only on appearance.
