What does URL encoding do?

It replaces reserved characters like spaces, &, ? and # with percent-escapes so a string is safe inside a URL or query parameter.

Does decoding handle %20 and %E4%B8%AD?

Yes — both percent-escapes and UTF-8 byte sequences decode back to the original characters.

Is anything uploaded?

No — this tool runs entirely in your browser.
