About the url encoder / decoder
URLs may only contain a limited set of characters. Percent-encoding replaces anything else — spaces, accents, ampersands — with a % followed by a hex code, so the address survives being passed between servers and browsers.
“Encode” keeps structural characters like : / ? & intact, which is right for a whole URL. “Encode component” escapes those too, which is what you want for a single query-string value.
Decoding reverses the process so you can read what an encoded link actually contains. Everything runs locally in your browser.
