Created on 6 October, 2025 • Text Tools • 33 views • 2 minutes read
Translate international domain names (IDN) to and from Punycode. Our free IDN Punycode Converter helps manage global domains and identify phishing threats.
The internet used to be mostly English. But now, websites exist in every language, using characters like Arabic, Chinese, or Cyrillic. How do these non-English web addresses work with the core internet systems that primarily understand Latin characters?
The answer is Punycode.
What is an IDN Punycode Converter? (A Simple Analogy)
Imagine you have a secret, universal language spoken by all the internet's core systems (like servers and routers). This language only understands basic English letters and numbers.
Now, imagine someone wants to name their website "https://www.google.com/search?q=%D9%85%D8%AB%D8%A7%D9%84.com" (which means "example.com" in Arabic).
An IDN Punycode Converter is like a universal translator for web addresses. 🗣️🔄🌐
It takes the human-friendly, foreign-language web address (like "https://www.google.com/search?q=%D9%85%D8%AB%D8%A7%D9%84.com") and translates it into a special, encoded English-only version (like "https://www.google.com/search?q=xn--mgbh0fb.com") that the internet's core systems can understand. Then, it can translate it back for your browser to display correctly.
How to Use Our IDN Punycode Converter Tool
Translating domain names is a two-way street:
- Step 1 (To Punycode): Enter a human-readable Internationalized Domain Name (IDN) like "https://www.google.com/search?q=%E4%BD%A0%E5%A5%BD.com" into the input box.
- Step 2 (From Punycode): Alternatively, enter a Punycode string like "https://www.google.com/search?q=xn--6qqa0888a.com".
- Step 3: Click the "Convert" button.
- Step 4: The tool will instantly convert the domain name to its Punycode equivalent or back to its human-readable IDN form.

Why is This So Useful? Key Benefits
- ✅ Global Accessibility: Enables people around the world to use domain names in their native languages, making the internet truly global.
- Technical Compatibility: Allows these international domain names to function seamlessly with existing internet infrastructure that relies on ASCII (English alphabet) characters.
- Prevent Phishing (IDN Homograph Attacks): Helps developers and security analysts identify domains that use similar-looking characters from different alphabets to mimic legitimate sites (e.g., using a Cyrillic 'a' that looks like a Latin 'a').
- Domain Management: Essential for domain registrars, hosting providers, and web developers who work with international domain names.
Punycode in Action: Real-World Scenarios
1. Registering an International Domain A Chinese business wants to register the domain "https://www.google.com/search?q=%E4%BD%A0%E5%A5%BD.com" (nǐ https://www.google.com/search?q=h%C7%8Eo.com). They use a Punycode converter to get the technical name "https://www.google.com/search?q=xn--6qqa0888a.com," which is what they actually register with the domain provider.
2. Identifying a Phishing Site A security analyst receives a suspicious link that looks like paypal.com but might be paypaⅼ.com (using a Cyrillic 'l'). They paste it into the Punycode converter. If it converts to something like xn--paypa-gjc.com, they know it's a phishing attempt.
Decoding the Data: The xn-- Prefix
You'll notice that Punycode always starts with xn--. This is a special prefix that tells internet systems, "Hey, this is an Internationalized Domain Name that has been converted from non-ASCII characters." It's like a flag indicating that a translation has occurred.
Conclusion
Punycode is the unsung hero that allows the internet to speak every language. Our IDN Punycode Converter provides a vital bridge between diverse human languages and the underlying ASCII-based internet infrastructure.
