What is URL encoding?

URL encoding (percent-encoding) replaces unsafe characters with a % followed by two hex digits. For example, a space becomes %20.

When should I encode a URL?

Encode query parameter values before appending them to a URL to ensure special characters like &, =, and + are treated as data, not syntax.
