Free Online URL Query String Builder

Build a URL query string from key/value pairs. Add or remove rows, choose whether to percent-encode values, and optionally include a leading ? — all privately in your browser.

Options

  • Include ? prefix — produce ?a=1&b=2 instead of a=1&b=2
  • Encode values — percent-encode keys and values safely
  • Repeated keys are supported for multi-value parameters
