Query String Editor

Replace a URL’s query parameters from a JSON object.

Try the sample, paste your own input, or load a local file where offered.

How to use this tool

Existing query parameters are replaced; the path and fragment remain. Use string or number values, or arrays to repeat a key. This does not visit the URL.

Your inputs and files are processed in this browser. This tool does not send them to a server or save an input history. Copy or download any results you want to keep.
