Punycode Converter

About the tool

Punycode is a special encoding used to convert Unicode characters to ASCII, which is a smaller, restricted character set. Punycode is used to encode internationalized domain names (IDNs) so that they can be registered in the DNS.

This tool allows you to encode and decode IDNs using Punycode.
