Query String Parser
Paste a full URL or just a query string and this tool breaks it into a clear table of parameter names and values, decoding each one so you can read them properly. Long tracking laden URLs are hard to inspect by eye, and repeated keys or nested encoding make it worse. This parser splits on ampersands, percent decodes each key and value, and shows repeated parameters as separate rows so nothing is hidden. It is exactly what you need when debugging a redirect, auditing UTM tags, or figuring out what an API call is actually sending. It also shows the path and origin when you paste a whole URL. Everything is parsed locally in your browser, so links containing tokens or private identifiers never leave your device.
How to use Query String Parser
- Paste a URL or query string.
- Read the decoded parameters in the table.
- Copy the values you need.
