Free Online URL Encoder & Decoder Tool | Supports Korean & Special Characters

Copy Result

This free online tool allows you to quickly and easily perform URL encoding and decoding. It converts all characters—including Korean, special characters, spaces, and emojis—based on UTF-8, and runs directly in your browser for enhanced security and speed. The encoding function safely converts characters to prevent them from breaking during URL transmission, while the decoding function restores encoded URLs to a human-readable format. Web developers can use it for sending GET parameters, marketers for creating campaign links, publishers for attaching safe links in posts, and data analysts for interpreting encoded URLs in log files. With just a click on the Encode or Decode button, you can instantly see the result, and the copy button lets you paste it in one go. Since it runs entirely in the browser without going through a server, there is no risk of personal information leakage, and it works reliably in various environments.
