What is URL encoding?

URL encoding replaces special characters with a percent sign followed by two hex digits (e.g. space becomes %20). It ensures URLs are transmitted correctly.

When do I need to encode a URL?

Whenever you include special characters like spaces, &, =, or # in query parameters, you need to encode them so they don't break the URL structure.

Does it encode the entire URL or just parts?

You can encode individual query parameter values or full URL strings. Encoding a full URL preserves the slashes and protocol.
