What is url decoder?
Percent-encoding hides readable characters behind %XX sequences. Paste an encoded URL or query string and get the original text back, including multi-byte UTF-8 characters like emoji and accented letters.
If the input contains a broken sequence — a % not followed by two hex digits — the tool explains the problem instead of producing garbled output.

Frequently asked questions
Percent-decoding does not treat "+" as a space; that convention belongs to form encoding. Replace "+" with "%20" first if you are decoding a form query string.
