What URL encoding is
URL encoding converts special characters into percent-encoded sequences so they can be safely passed in URLs. For example, spaces become %20.
When to use it
Use it when building query strings, API requests, or redirect URLs. It prevents broken links and ensures parameters are transmitted correctly.
Encode vs. decode
Encoding turns readable text into a URL-safe format. Decoding reverses it back to plain text for debugging or inspection.

+ is used in query strings, while %20 is standard URL encoding.
