What does a URL decoder do?

A URL decoder reverses percent-encoding, turning %XX sequences back into the characters they represent. It makes long, encoded tracking URLs and query strings readable so you can see exactly what they contain.

Frequently Asked Questions

When should I enable '+ as space'?

Enable it for application/x-www-form-urlencoded data (HTML form submissions), where spaces are encoded as +. Leave it off for standard URLs.

Why does decoding fail?

A malformed escape sequence (like a stray % not followed by two hex digits) can't be decoded. Check the input is complete and valid.

Is it free and private?

Yes — it's 100% free with no signup, and everything runs locally in your browser, so your data is never uploaded to a server.
