What happens with invalid percent sequences?

If the input contains malformed percent sequences (e.g., %ZZ), the tool will display a clear error message instead of producing garbled output.

Does it decode plus signs as spaces?

The tool uses decodeURIComponent which decodes %20 as spaces. If your input uses + for spaces (common in form data), you can replace them before decoding.

Can I decode entire URLs?

Yes. Paste the full URL or just the encoded portion. The decoder will convert all percent-encoded sequences back to their original characters.
