Punycode converter

Paste a Unicode domain or an xn-- label. Conversion is local using standard IDNA mapping.

Homograph attacks hide in look-alike letters. If a link’s punycode is not the brand you expect, do not log in there.

How to Use

  1. Paste the hostname (no scheme).
  2. Convert both directions and compare with what your registrar shows.
  3. Use the ASCII form in older DNS tools that reject Unicode.
  4. Follow with WHOIS if you are checking registration.
