Unicode to Punycode Converter – Convert International Domains Instantly

Free Punycode Converter Tool – Academy of Digital Marketing

At the Academy of Digital Marketing, we help make the internet more accessible and functional across languages and platforms. Our Unicode to Punycode Converter tool allows you to convert internationalized domain names (IDNs) from human-readable Unicode characters to browser-compatible Punycode, and vice versa—instantly and accurately.

What is Punycode?

Punycode is a way to represent Unicode characters using the limited character set supported by the Domain Name System (DNS)—specifically, ASCII. It enables domain names containing special characters (like accents, non-Latin alphabets, or symbols) to be used on the internet.

For example:

makefile
Copy
EditUnicode: münich.de  
Punycode: xn--mnich-kva.de

This conversion is essential for supporting global domain names while maintaining DNS compatibility.

Why Should You Use the "Unicode to Punycode Converter"?

Understanding and converting Punycode is important for:

  • Registering IDNs (Internationalized Domain Names): Convert human-readable names into DNS-compliant ASCII.
  • Browser Compatibility: Ensure domains render correctly in all browsers and systems.
  • Security Verification: Identify homograph spoofing in domains (e.g., “раypal.com” vs “paypal.com”).
  • Localization Testing: Web developers and marketers can validate domain appearance and redirects across regions.
  • Email Server Configuration: Email protocols often require ASCII-compatible domain handling.
