Punycode converter: one address for people and DNS
Convert domains containing Ukrainian, Cyrillic or other national characters to the technical xn-- format and back. Everything is processed locally in your browser.
IDN ↔ ASCII
Domain to convert
You may paste a full URL; the protocol, path and query will be removed.
How it works
What is Punycode and why is it needed?
DNS was designed around Latin letters, digits and hyphens. Punycode represents domain names containing national characters in compatible ASCII. A human-readable name may therefore be stored technically as an address beginning with xn--.
DNS and SSL
Use the ASCII form in configuration fields that do not accept Unicode.
Safer inspection
Decode an xn-- address before visiting it to see the readable spelling.
!
Check look-alike characters carefully
Characters from different scripts can look almost identical. Punycode does not determine whether a domain is safe; it only changes its representation. Verify spelling, the certificate and the source of a link.
FAQ
Frequently asked questions
Does conversion change the owner or settings?+
No. It only displays two representations of the same IDN domain.
Is the domain sent to a server?+
No. JavaScript performs the conversion in your browser.
Can I paste a full page URL?+
Yes. The tool removes the protocol, path and query before processing the hostname.
What does the xn-- prefix mean?+
It marks a domain label encoded with the Punycode standard.
