About URL Encoding

URL encoding (percent-encoding) replaces characters that are not permitted in a URL with a % followed by two hexadecimal digits. It keeps query strings, path segments and form data unambiguous when they travel over HTTP.

Common uses

• Passing values safely in query-string parameters
• Encoding form data submitted as application/x-www-form-urlencoded
• Building API request URLs that contain spaces or symbols
• Preventing malformed URLs and injection through unescaped input
