What is IDN Decoding?

IDN decoding converts Punycode (xn-- format) back to human-readable international characters. When you see "xn--mf-hia.com" in your browser's address bar, the browser decodes it to "müf.com" for display. This tool shows you the actual Unicode representation behind any Punycode domain.

Frequently Asked Questions

Why do I see xn-- in my browser?
Some browsers show Punycode for domains with mixed scripts or potential homograph attacks. It's a security feature to prevent lookalike domains from tricking users.
How do I know if a domain uses Punycode?
Any domain starting with "xn--" is Punycode-encoded. For example, "xn--caf-dma.fr" decodes to "café.fr". Our decoder reveals the original characters.
Can Punycode be used for malicious purposes?
Yes, homograph attacks use similar-looking characters. That's why our decoder helps you inspect domains before trusting them. Always verify the Unicode output matches the expected domain.
