Convert internationalized domain names (IDNs) to Punycode and back with ease. Learn how an IDN Punycode converter works and use our free online tool at shorterlink.xyz.

Have you ever come across a domain name with special characters or accented letters and wondered how browsers interpret them? That’s where an IDN Punycode converter comes in. This essential tool helps convert domain names with Unicode characters (like emojis or non-English letters) into ASCII-compatible Punycode — and vice versa.

At shorterlink.xyz, we offer a free, easy-to-use IDN to Punycode converter that works right in your browser.

What is Punycode?

Punycode is a special encoding method used to represent Unicode characters (such as ä, é, ü, or even emojis 😃) using only the limited ASCII characters allowed in domain names.

Why is it needed?

The Domain Name System (DNS) only supports ASCII characters — the basic English alphabet, numbers, and hyphens. But many domain names now include non-ASCII characters (e.g., café.com, 北京.cn, or 🌍.com), which require conversion for DNS to recognize and process them properly.

That conversion is made possible using Punycode.

What is an IDN?

IDN stands for Internationalized Domain Name. These are domain names that contain characters from non-Latin alphabets like Arabic, Chinese, Cyrillic, and other Unicode symbols.

Examples of IDNs:

münchen.de → Contains "ü"

東京.jp → Japanese characters

президент.рф → Cyrillic script

When used in a web browser or DNS system, these domains are encoded into ASCII using Punycode.

How Does an IDN Punycode Converter Work?

An IDN Punycode converter is a tool that encodes and decodes domain names between Unicode (human-readable format) and Punycode (DNS-compatible format).

It has two main functions:

Encode: Convert Unicode domain (IDN) to Punycode
Example: münchen.de → xn--mnchen-3ya.de

Decode: Convert Punycode back to Unicode
Example: xn--mnchen-3ya.de → münchen.de

At shorterlink.xyz, our online converter performs both operations instantly and without requiring installation or registration.

Real-World Example: How Punycode Helps with IDNs

Imagine you want to register the domain mañana.com. DNS cannot process the “ñ”, so the Punycode version xn--maana-pta.com is stored and used behind the scenes. Without a tool like shorterlink.xyz’s IDN Punycode converter, you wouldn’t easily know what the correct Punycode is — or if your domain was even valid.
