About URL Encoding
URL encoding (percent encoding) replaces special characters with a percent sign followed by their hexadecimal value. For example, spaces become %20 and ampersands become %26. This ensures URLs are valid and correctly interpreted by web browsers and servers.
Common Use Cases
- Encoding query string parameters for safe URL construction
