Why are some characters still %-encoded after decoding?

Sometimes a URL is double-encoded (%2520 instead of %20). Run the decoder twice to fully unwrap it.

Will it break if the URL has malformed escapes?

Malformed sequences (like a lone % with no two hex digits) are kept literally and the tool reports a warning instead of throwing.

Can I decode just one query parameter?

Paste only that value — for example the contents of a state= or redirect_uri= field.

How to use URL Decoder

1Paste a percent-encoded URL or query string into the decoder.
2Every %XX is converted back to its original byte; sequences of bytes are interpreted as UTF-8.
3Both + and %20 are decoded to spaces, so form-encoded and standard URL-encoded inputs both work.
4If the input is a full URL, the decoder also parses and lists each query parameter on its own line.
5Copy the readable result, or paste a fresh string to decode another.
