About this tool
Applies and reverses percent-encoding, with a choice between component encoding — which escapes the reserved characters &, =, ?, / and # — and full-URI encoding, which leaves the structural ones intact. Picking the wrong one is a common source of parameters that silently truncate.
Paste a complete URL and the tool also splits it into its parts and lists the query parameters decoded, which is often faster than reading a long encoded string character by character.
How to use it
- 1Paste your URL or text fragment.
- 2Choose encode or decode, and component or full URI.
- 3Check the query parameter table when you pasted a complete URL.
