Understanding URL Encoding

URL encoding (also called percent encoding) converts special characters in URLs to a format that can be safely transmitted over the internet. Special characters are replaced with a percent sign (%) followed by two hexadecimal digits representing the character's ASCII code. For example, a space becomes %20, and an ampersand (&) becomes %26.

Which Characters Are Encoded?

URL encoding is required for characters that have special meaning in URLs or are not safe for transmission:

• Reserved characters: : / ? # [ ] @ ! $ & ' ( ) * + , ; =
• Unsafe characters: Space, ", <, >, {, }, |, \, ^, `, and non-ASCII characters
• Safe characters (not encoded): A-Z, a-z, 0-9, -, _, ., ~

Common Encoding Examples

• Space: " " → %20 or +
• Ampersand: & → %26
• Question mark: ? → %3F
• Equals: = → %3D
• At sign: @ → %40
• Forward slash: / → %2F
