About Punycode Converter
A Punycode converter handles domain names with accents or non-Latin letters, such as münchen.de or Chinese domains, which DNS stores as Punycode, an ASCII form that starts with xn--. You need that form when a DNS panel, certificate request, server config or mail system won't take the original name, and you need to decode it when a log file or certificate shows something like xn--fiq228c.com and you want to know what it says.
Paste one name per line and each line is converted in the direction it needs. Names with Unicode letters become xn-- names and xn-- names are decoded, so a mixed list works. Full web addresses and email addresses work too, with the domain inside them converted. Everything runs in your browser, so nothing is uploaded, it isn't counted as a task and it keeps working offline once the page has loaded. Characters in the rest of a URL use percent-encoding instead, which URL Encode and Decode handles.
