What is percent-encoding?

It replaces unsafe or reserved characters (like spaces and &) with a % followed by a hex code, so they can safely appear in a URL.

Why does a space become %20 or +?

%20 is the standard percent-encoding for a space in a URL path; a + is sometimes used specifically in query strings. Check which your target system expects.

Is my text sent to a server?

No. Encoding happens entirely in your browser.
