What happens with invalid encoded sequences?

You'll see an error message — the input must be valid percent-encoding to decode successfully.

Does it decode + as a space?

No — this tool decodes standard percent-encoding (%20 for spaces), not the application/x-www-form-urlencoded convention where + means space.

Can I decode an entire query string at once?

Yes, paste the whole string — each %XX sequence is decoded in place.
