About the Query String Parser

A query string is the part of a URL after the question mark, holding key/value pairs separated by ampersands.

Paste a query string or a full URL and this tool decodes it into a readable table of parameters.

It handles repeated keys, plus-encoded spaces and percent-encoding, all in your browser.

Each occurrence is listed as its own row, so you can see every value for a repeated key.
