What is an Internationalized Domain Name (IDN)?

An IDN is a domain name that contains non-ASCII characters, such as accented letters or characters from languages like Chinese, Arabic, and Cyrillic.

Punycode is a way to encode domain names that contain Unicode characters into an ASCII format that can be used by the Domain Name System (DNS).

What is the difference between IDN and Punycode?

IDN refers to domain names that contain non-ASCII characters, while Punycode is the ASCII-compatible encoding used to represent them. For example, 'münich.de' in IDN format becomes 'xn--mnchen-3ya.de' in Punycode.

Why do I need to convert IDN to Punycode?

Some systems, such as domain registrars and older browsers, require Punycode for compatibility with non-ASCII domain names.

Can I convert Punycode back to IDN?

Yes, you can decode a Punycode domain back into its original IDN format.

Does Punycode affect website ranking or SEO?

No, search engines recognize both IDN and Punycode versions of a domain. However, it's best to be consistent with usage to avoid confusion.

Can I use Punycode for email addresses?

Yes, but email providers may handle internationalized email addresses differently. Check with your provider for support.

Do all browsers support IDN?

Most modern browsers support IDN, but some older versions may still display Punycode instead.

Are there security risks with IDN?

IDN homograph attacks (where visually similar characters are used to mimic another domain) can be a concern. Always verify domain authenticity.

Is this tool free to use?

Yes! Our IDN Converter is completely free to use with no limitations.
