How to use the idn converter

The IDN converter translates internationalized domain names between readable Unicode and ASCII-compatible Punycode. DNS uses the ASCII form, while browsers may display a localized form when it is considered safe.

Good reasons to use it

  • Prepare a non-ASCII domain for DNS or technical configuration.
  • Reveal the Punycode behind an internationalized hostname.
  • Compare visually similar characters during a phishing review.

A reliable workflow

  1. Paste the domain label in Unicode or its xn-- Punycode form.
  2. Choose the conversion direction and run the tool.
  3. Verify the complete hostname with the registrar or authoritative DNS.

How to interpret the result

Punycode represents characters; it does not confirm that a domain is registered, safe or owned by the expected organization. Pay close attention to mixed scripts and visually similar characters.

Frequently asked questions

Why does an IDN begin with xn--?

That prefix marks an ASCII-compatible Punycode label used by DNS for international characters.

Does conversion register the domain?

No. It only changes representation. Registration must be checked with a registrar or WHOIS source.
