Convert an international domain to Punycode

Convert an international domain to Punycode. Useful for developers and administrators checking data before an import, form submission or integration.

Convert an international domain to Punycode. See the result immediately in your browser, with no account, upload or stored data.

How to use

Type the domain you want to convert, including its accented or non Latin characters.
Run the conversion and the rewritten form appears immediately in the area below.
Copy the value and paste it into your spreadsheet, form or configuration file.
Clear the field whenever you want to test another domain from scratch.

Example

The sample starts from the domain münchen-example.com. After converting, look at how the accented part has been rewritten: the result uses plain Latin letters, digits and hyphens, which lets systems that do not handle accents process the same domain name.

Input

münchen-example.com

Output

xn--mnchen-example-gsb.com

Limits and formats

The page only rewrites text: it cannot tell you whether a domain exists or is available.
A misspelled domain converts without any warning, so read your input again before copying anything.
Copy the whole converted value, without adding a space or trimming the beginning of the result.
With a very long domain, compare the result character by character before an import.

Where processing happens

The domain you type is rewritten by the page inside your browser, without leaving your machine. No log is kept and the value disappears as soon as you clear the field or close the tab, which makes it easy to test private names.

Frequently asked questions

What is the converted form of a domain used for?

Some systems, forms and import files only accept plain Latin characters. The converted form lets you pass the same domain through those tools without accents, while still pointing to the same address.

Can this tool tell me whether my domain is spelled correctly?

No, it only rewrites the text you give it. A domain that does not exist, or one you mistyped, will be converted without any warning, so check your entry before pasting the value into a form.

Why convert a domain before importing data?

Because many scripts and exchange formats handle plain Latin characters more predictably. Storing the converted form reduces the risk of encoding surprises and of duplicates between two spellings of the same domain.
