What Is URL Decoding?

URL decoding reverses percent-encoding, converting %XX sequences back into their original characters — turning "hello%20world" back into "hello world", for example.

It is useful whenever you have a URL or query string copied from a browser's address bar, server log, or API response and want to read its actual, human-readable content.
