What the IDN-decode Text Tool can do:

This tool reads domains encoded using Punycode (typically starting with xn--) and decodes each one into its full Unicode form. Whether you’re working with Cyrillic, accented Latin characters, or other scripts, the tool converts each label in-place, maintaining full domain structure. It includes optional whitespace trimming and empty line handling, and works entirely client-side for fast and private processing.

Example:

Input:

xn--mnich-kva.de
xn--e1afmkfd.xn--p1ai
xn--bcher-kva.example

Output:

codemünich.de
пример.рф
bücher.example

Common Use Cases:

Use this tool to inspect user-submitted domains, decode API results, or clean up lists of encoded domains before storing or displaying them. It’s especially helpful for SEO audits, registrar tools, or multilingual web systems. Everything decodes instantly in your browser with no server contact, so it’s fast and completely private.

Useful Tools & Suggestions:

If you’re working with international domain names, IDN-encode Text flips readable characters back into Punycode perfect for DNS systems and browser compatibility. And when you want to handle full URLs with special characters, URL Encoder helps you safely prepare them for use across the web.
