What does this tool do?
Encode structured query entries, preserving their order, repeated keys and empty values. Inputs: Query parameters. Outputs: Query string.
How to use it?
Enter query parameters, then choose “Generate”. Copy copies the displayed result or the labeled example/decoded value. Clear removes inputs and results and restores initial options.
Processing is local. Entered URLs are data: they are not visited, uploaded, logged or placed in the route. Generated markup is inert text. Reference lookups use bundled data, and previews are illustrative rather than guaranteed platform output.
Empty keys are valid in URLSearchParams. Spaces encode as +. With no rows the result is ?.
