What is URL Encoding?

URL encoding (percent-encoding) is a mechanism for encoding information in a Uniform Resource Identifier (URI). Characters that are not allowed in a URL must be encoded.

How it Works

Non-ASCII characters are replaced with a "%" followed by their hexadecimal value. For example, a space becomes "%20" and "&" becomes "%26".

Use Case

It is essential when passing data through URL parameters (query strings) to ensure that special characters don't break the URL structure or get misinterpreted.
