Punycode / IDN Converter

Convert internationalized domain names (IDN) between their Unicode form (пример.рф) and ASCII/Punycode form (xn--e1afmkfd.xn--p1ai). Paste a single domain, a full URL or an entire list — each line is converted separately.

Runs 100% in your browser — nothing is sent to any server.

The converter checks syntax only — it does not query registries or verify that a domain exists.
