IDN Punycode converter

The core internet DNS system was originally designed to only understand standard English letters and numbers. This character set is known as ASCII.

To allow people to register domains in native languages (like Arabic, Chinese, or Cyrillic) or use emojis, the internet uses Punycode. Punycode is a special encoding that translates a non-English character into a safe string of letters starting with `xn--`.

This tool runs securely in your browser to instantly convert your internationalized domain (IDN) into the exact format you need to configure servers, SSL certificates, or registrar settings.

While registering an emoji domain can be a fun marketing stunt, they come with significant tradeoffs. Many email providers and social media platforms do not recognize them properly.

Additionally, users cannot easily type an emoji on a standard desktop keyboard. If you use an IDN, treat it as a novelty redirect rather than the primary home for a serious brand.
