About URL Encoding
URL encoding (percent-encoding) replaces special characters with a % followed by their hexadecimal ASCII value. This ensures URLs can be safely transmitted across the internet.
Encoding Modes
- Component: Encodes everything except A-Z a-z 0-9 - _ . ! ~ * ' ( ). Use for query parameters.
- Full URL: Preserves URL structure (://?#). Use for complete URLs.
- All Characters: Encodes every character to percent-encoding.
Common Encodings
| Character | Encoded | Character | Encoded |
|---|---|---|---|
| Space | %20 | & | %26 |
| = | %3D | ? | %3F |
