URL Decoder
Decode percent-encoded URLs and expand query parameters into a table.
Nothing decoded yet
Paste an encoded value or a whole URL. A full URL is broken down into its parts with every query parameter listed.
Runs entirely in your browser. Your data isn't uploaded — this page makes no network request with anything you type, which you can verify in your browser's network tab. How this works.
What is the URL Decoder?
Decoding a URL is usually the first step in debugging a redirect chain, an OAuth callback or a tracking link, and the interesting information is rarely the decoded string itself — it is the parameters hidden inside it.
This tool decodes percent-encoding and then breaks the URL apart: scheme, host, port, path, fragment, and every query parameter in a table, including repeated keys and nested encoded URLs.
How to use it
- Paste the encoded URL or value.
- Press Decode (or Ctrl/Cmd + Enter).
- Read the parsed table to see each query parameter separately.
- Use Decode again on any nested value that is still encoded.
Example
A callback URL decoded and broken into parameters.
https://app.example.com/callback?next=%2Fdashboard%3Ftab%3Dbilling&state=abc
path /callback next /dashboard?tab=billing state abc
