Frequently Asked Questions
What is Punycode?
A way to represent internationalized domain names using only the ASCII letters that the domain system allows, with an xn-- prefix.
How is each part handled?
Each label between the dots is converted on its own, so only the parts that need encoding are changed.
Does it convert both ways?
Yes. Encode a Unicode domain to Punycode, or decode an xn-- domain back to Unicode.
Is my data sent anywhere?
No. The conversion runs entirely in your browser, so your domain never leaves the tab.
Is it free?
Yes. Every tool here is free to use with no sign up.
