About URL Encoding

URL encoding (also known as percent encoding) is a mechanism to encode information in a Uniform Resource Identifier (URI) under certain circumstances. It converts characters into a format that can be transmitted over the Internet.

Encoding Rules

Reserved Characters: : / ? # [ ] @ ! $ & ' ( ) * + , ; =
Unsafe Characters: Space, ", <, >, #, %, {, }, |, \, ^, ~, [, ], `
Encoding Format: % followed by two hexadecimal digits
Space Encoding: Can be %20 or + (in query strings)

Common Character Encodings

Space → %20 or +

! → %21

" → %22

# → %23

$ → %24

% → %25

& → %26

' → %27

( → %28

) → %29

+ → %2B

, → %2C
