Punycode Encoding and Decoding

Tool Introduction

This tool provides Punycode encoding and decoding functions, used to convert between Chinese domain names and Punycode strings. It facilitates users to perform domain operations in environments that do not support Chinese domain names, or to convert Punycode domain names into easy-to-read Chinese domain names.

How to Use

1. Enter the string to be encoded or decoded in the "Before encoding" text box.
2. Click the corresponding "Encode" or "Decode" button (the tool automatically identifies the input content for encoding or decoding).
3. The "After encoding" text box will display the converted result.

Frequently Asked Questions

• Q: What input formats are supported?
• A: Chinese domain names, English domain names, and Punycode strings are supported.
• Q: What is the output format?
• A: Encoding outputs Punycode strings, and decoding outputs Chinese domain names.
• Q: Are there any usage restrictions?
• A: Punycode encoding has length limitations; excessively long domain names may not be encoded correctly.

Notes

• Please ensure the input domain name format is correct.
• When encoding, only the domain name part is Punycode encoded; other parts (e.g., http://) do not need to be encoded.
• When decoding, the tool automatically determines if it is in Punycode format, no manual specification is required.
