Convert Unicode domain names (IDNs) to ASCII-safe Punycode.
With the growth of the global internet, domain names can now contain non-English characters like accents, symbols, or characters from non-Latin scripts. These are known as Internationalized Domain Names (IDNs). While they improve accessibility and branding, domain systems still rely on ASCII — the English-based character set.
That’s where Punycode comes in. Our Unicode to Punycode Converter allows you to take a Unicode domain like münich.de or 東京.jp and convert it to an ASCII-safe format that can be recognized by web browsers and DNS systems.
Punycode is a special encoding system used to represent Unicode characters in domain names using only ASCII characters. It ensures that internationalized domains can be transmitted over systems that only understand standard English letters (A–Z), numbers (0–9), and hyphens.
Example:
The xn-- prefix identifies the domain as Punycode-encoded.
You need to use Punycode when registering, managing, or troubleshooting internationalized domain names. Most web browsers and DNS systems convert Unicode domains into Punycode behind the scenes, but for hosting, SSL setup, or DNS configuration, you may need to enter the ASCII version manually.
The Unicode to Punycode Converter helps you:
It’s fast, accurate, and helps prevent common encoding issues that can lead to website errors or SSL mismatches.
If you’re working with domains that include accents, umlauts, or non-Latin characters, using Punycode is essential to ensure proper functionality. Our Unicode to Punycode Converter gives you a fast, reliable way to encode domains for full compatibility across browsers, DNS, and hosting systems.
