Punycode Converter

Welcome to our Punycode Converter website, where you can easily perform conversions between Unicode domains and ASCII domains. In this article, we will provide a detailed introduction to Punycode, including its definition, usage, and support in various environments.

Punycode is an encoding system based on the RFC 3492 standard, designed to convert domain names that use the Unicode character set into ASCII-compatible encoding recognizable by the DNS system. The main purpose of Punycode is to ensure that Internationalized Domain Names (IDNs) are compatible with traditional DNS systems, preventing IDN spoofing and resolution errors.

Early DNS (Domain Name System) only supported English characters, making it difficult for global users to use domain names in their native languages. The introduction of Internationalized Domain Names (IDNs) allows users to register domains in their local languages. However, to ensure compatibility with existing DNS systems, these IDNs need to be converted into Punycode format. Punycode domains consist of 26 letters, 10 digits, and the hyphen "-", ensuring compliance with existing DNS specifications.

Today’s mainstream browsers automatically convert internationalized domain names to Punycode format. This means that when users enter domain names in Chinese or other local languages in the address bar, the browser automatically converts them to the corresponding Punycode to ensure correct resolution and access.

Using our Punycode converter is very simple. Just enter the domain name you want to convert, whether it is a Unicode domain or an ASCII domain, and our tool will instantly perform the conversion for you.

Example:

Entering ".网址" will convert to "xn--ses554g"

Entering ".公司" will convert to "xn--55qx5d"

Here are some common Punycode domain examples:

.网址 (xn--ses554g)
.在线 (xn--3ds443g)
.公司 (xn--55qx5d)
.移动 (xn--6frz82g)
.购物 (xn--g2xx48c)
.游戏 (xn--unup4y)
.谷歌 (xn--flw351e)
.亚马逊 (xn--jlq480n2rg)
.北京 (xn--1lqs71d)
.政务 (xn--zfr164b)
.政府 (xn--mxtq1m)

If you want to use your internationalized domain name on Twitter or other social media platforms, simply convert it to Punycode format. For example, convert the Chinese domain name to a Punycode domain and then copy and paste it into your Twitter post.
