Convert Internationalized Domain Names (IDNs) to Punycode and back with DAMTool's free IDN Punycode Converter. Fast, accurate, and browser-based.
Managing multilingual domain names can be confusing, especially when websites use non-Latin characters such as Arabic, Chinese, Japanese, or Cyrillic. Many browsers display these domains normally, but behind the scenes they rely on a special format called Punycode for compatibility with the Domain Name System (DNS).
Our IDN Punycode Converter instantly converts Internationalized Domain Names (IDNs) into Punycode and converts Punycode back into readable Unicode domains. Simply enter a domain name, click once, and get accurate results in seconds, no downloads or registration required.
What Is an IDN Punycode Converter?
An IDN Punycode Converter is an online tool that converts domain names containing Unicode characters into the ASCII-compatible Punycode format used by DNS. It can also decode Punycode back into its original human-readable domain name.
For example:
Internationalized Domain Name (Unicode)
مثال.إختبار
Punycode
xn--mgbh0fb.xn--kgbechtv
The conversion allows browsers, DNS servers, and internet infrastructure to support websites written in languages other than English.
Key Features
Why Use an IDN Punycode Converter?

Real-World Example
Suppose your company registers the domain:
café-example.com
Before configuring DNS records or certain server settings, the domain may need to be converted into its Punycode equivalent.
Instead of performing the conversion manually, simply paste the domain into the IDN Punycode Converter to generate the correct ASCII representation instantly.
Best Practices
For the best results:
- Enter complete domain names without protocols such as https://.
- Verify the converted domain before updating DNS settings.
- Use Unicode domains only when your registrar supports IDNs.
- Double-check spelling to avoid configuration errors.
Common Mistakes
Some users:
- Confuse Punycode with URL encoding.
- Attempt to convert full URLs instead of domain names.
- Include paths or query parameters during conversion.
- Assume Punycode changes website content, it only changes how the domain name is represented.
Security & Privacy
Your domain name is processed directly in your browser. DAMTool does not require registration, allowing you to convert IDNs quickly while maintaining your privacy.
Comparison
Important Note
Punycode is designed specifically for domain names. It should not be used to encode complete URLs, file paths, or general text.
Pro Tip
If you encounter a domain beginning with xn--, it's almost certainly a Punycode-encoded Internationalized Domain Name. Use this tool to decode it into its original readable form.
Expert Insight
Internationalized Domain Names make the web more accessible by allowing domain names in native languages. Punycode acts as the bridge between human-readable Unicode characters and the ASCII-only infrastructure used by the global DNS, ensuring compatibility across browsers, servers, and networking systems.
