About URL Encoding/Decoding
URL encoding converts characters into a format that can be transmitted over the Internet. It replaces unsafe ASCII characters with a "%" followed by two hexadecimal digits.
Commonly encoded characters include:
- Space → %20
- ! → %21
- # → %23
- $ → %24
- % → %25
- & → %26
- ' → %27
- + → %2B
- , → %2C
- / → %2F
- : → %3A
- ; → %3B
- = → %3D
- ? → %3F
- @ → %40
URL decoding is the reverse process that converts encoded characters back to their original form.
