IDN Punnycode converter
Use the IDN Punnycode converter to switch between internationalized domain text and Punycode/ASCII. Choose a direction and inspect the converted hostname.
IDN Punnycode converter: Convert Internationalized Domain Names
The IDN Punnycode converter helps you convert Internationalized Domain Names. Inspect a domain containing characters outside the basic Latin alphabet or compare a displayed name with its encoded form. Start with a short sample so you can see how the transformation relates to the text you supplied.
How to use the IDN Punnycode converter
Enter the domain representation in Content. Choose Convert to Punycode/ASCII or Convert to IDN/Text in Type, select Submit, and review the result. Keep an unchanged copy if the source matters, especially when you are preparing content for a document, website, or another application.
Example and practical checks
Compare an internationalized domain with its corresponding xn-- label. Keep the hostname separate from a full page path. Check the complete result rather than only its first line. A small test makes it easier to notice a missing item, unexpected spacing, or a character that did not display as intended.
What to check before copying
Similar-looking letters from different writing systems can represent different domain names. Conversion does not establish who owns a domain or whether a destination is trustworthy. The best input is the exact text you intend to work with. Avoid copying navigation labels or unrelated material along with your actual content.
Common questions
Does conversion register a domain?
No. A representation change does not create a registration, transfer ownership, or configure DNS.
Which tools can help with the next step?
Use the Character counter to review text length, the Text separator to adjust list delimiters, or the Duplicate lines remover to clean repeated entries. Choose the step that fits your source and inspect the result before continuing.
