When should I encode a URL?

Encode URLs when sending data via GET parameters to ensure special characters (like spaces, &, ?) don't break the link structure.

What is the difference between Encode and Decode?

Encoding turns "Example Text" into "Example%20Text". Decoding turns "Example%20Text" back into "Example Text".

What is Percent Encoding?

URL encoding, formally known as percent-encoding, is a mechanism for encoding information in a Uniform Resource Identifier (URI). Characters that are not allowed in a URL must be replaced with a percent sign followed by two hexadecimal digits.

RFC 3986 Safe Transmission UTF-8 Support

Why It Matters

Query Strings: Handle spaces and special symbols in search queries.
Data Integrity: Ensure that parameters like ampersands don't break the URL structure.
Universal Support: Safely transmit non-ASCII characters across different web servers.

Common Encoded Characters

Character	Encoded	Description
Space	%20 or +	Space character
!	%21	Exclamation mark
#	%23	Hash/pound sign
$	%24	Dollar sign
%	%25	Percent sign
&	%26	Ampersand
=	%3D	Equal sign

When to Use URL Encoding

Query parameters: Encoding values in URL query strings

Form submissions: When submitting form data via GET requests

API requests: Passing parameters in API URLs

Special characters: Including spaces, ampersands, or other special characters in URLs

International characters: Using non-ASCII characters in URLs
