local / URL query / privacy-first

Build a URL query safely.

Enter a URL and key=value pairs to build an encoded query locally.

Input

Base URLQuery (one pair per line)

Keys and values are encoded with URL rules and existing query parameters remain.
Input, conversion, copying, and download stay in this browser; the target is never contacted.
Relative URLs, non-HTTP(S) schemes, and lines without a key are out of scope.
