Paste a percent-encoded URL or query string to decode it back into readable text.
About URL decoding
This tool reverses percent-encoding, converting sequences like %20 back into their original characters (a space, in that example). Paste any encoded URL, query string, or parameter value to see the readable version.
FAQ
Why does it say "invalid input"? This happens if the text contains a malformed percent-sequence (like a stray % not followed by two valid hex digits).
