Frequently Asked Questions

What is IDN Decode?

Testsigma provides a free IDN Decoder that converts the domain name with special characters (Unicode) to their actual Punycode encoding.

How does IDN Decode work?

IDN domains work by decoding the domain name using a system called Punycode. The IDN Decode online tool converts the domain name to Punycode that you receive when you register for an IDN domain. When users enter a URL containing an IDN domain into their web browser, it converts the IDN domain into Punycode and resolves that domain.
