How to Use Punycode Converter - Step by Step Guide

Step 1

Choose Encode or Decode Mode

Select the conversion direction based on your needs. Punycode is a way to represent Unicode characters in ASCII-compatible format:

•
Encode Mode: Convert international domain names (with Unicode and special characters) into Punycode format for DNS compatibility
•
Decode Mode: Convert Punycode domains (starting with "xn--") back to their readable Unicode format
•
Auto-Detection: The tool automatically determines which conversion to apply based on your input

Example: When to Use Each Mode

Encode Example:

Input: münchen.de

Output: xn--mnchen-3ya.de

Decode Example:

Input: xn--caf-dma.fr

Output: café.fr

Type or paste your domain names into the input area. The tool supports various international characters and formats:

•
International Characters: German (ä, ö, ü), French (é, è, ç), Spanish (ñ), and more
•
Non-Latin Scripts: Chinese (中文), Japanese (日本語), Arabic (العربية), Cyrillic (Кириллица)
•
Unicode Coverage: Supports domain labels from many writing systems and accented character sets

Example: Conversion Results

See how international domains are converted to Punycode:

Original:münchen.de
Punycode:xn--mnchen-3ya.de
Original:日本語.jp
Punycode:xn--wgv71a119e.jp
Original:пример.рф
Punycode:xn--e1afmkfd.xn--p1ai

Note: The "xn--" prefix indicates that the domain is Punycode-encoded. This format is recognized by all modern DNS servers and browsers.

Frequently Asked Questions

What is Punycode and why do I need it?

Punycode is a way to represent Unicode characters (like Chinese or Arabic) in ASCII format for domain names. Since DNS only supports ASCII characters, Punycode allows international domain names to work on the internet.

How does Punycode encoding work?

Punycode adds an "xn--" prefix to encoded domain parts. For example, "münchen.de" becomes "xn--mnchen-3ya.de". The algorithm preserves ASCII characters and encodes only non-ASCII ones.

Can I convert Unicode domains with this tool?

Yes. The tool supports Unicode domain labels used in international domain names. You can convert domains written in many scripts to their Punycode equivalents. You can also use our URL Encoder for other URL encoding needs.

Is Punycode the same as URL encoding?

No, Punycode is specifically for domain names and uses a special algorithm. URL encoding (percent-encoding) is for URLs and query parameters. They serve different purposes in web standards.

Is the Punycode converter free to use?

Yes, completely free with unlimited conversions. No registration required, and you can convert as many domain names as you need with full Unicode support.
