Is my URL sent to a server?

No. Encoding, decoding, and query parsing run entirely in your browser.

What’s the difference between encodeURI and encodeURIComponent?

encodeURI keeps URL structure characters (like : / ?) intact. encodeURIComponent encodes nearly everything — use it for query values.

Why did decoding turn %26 into & inside my URL?

decodeURI / decodeURIComponent reverse percent-encoding. Decoding %26 to & can change how a URL’s query string is structured — prefer decoding individual parameter values.

Can I paste a query string without a full URL?

Yes. Paste ?utm_source=… or key=value pairs into Parse mode to inspect parameters in the table.
