What Is URL Encoding?
URL (percent) encoding replaces characters that are unsafe or reserved in URLs — spaces, &, ?, non-ASCII characters, and more — with a % followed by two hexadecimal digits. This ensures query strings and path segments are transmitted correctly across browsers, servers, and APIs.
Common Uses
- Building query string parameters that contain spaces or special characters.
- Safely passing non-English text (Korean, Japanese, etc.) in a URL.
- Decoding URLs copied from browser address bars or server logs.
