About URL Encoding

URL encoding (also known as percent-encoding) is a mechanism for encoding special characters in URLs. Characters that have special meaning in URLs (like &, =, ?) or non-ASCII characters need to be encoded to be safely transmitted.

How It Works

Each unsafe character is replaced with a percent sign (%) followed by its hexadecimal ASCII value. For example, a space becomes %20 or +.

Common Encodings

Space → %20 or +

& → %26

= → %3D

? → %3F

/ → %2F

: → %3A

# → %23

@ → %40

Use Cases
