Query String Builder
100% PrivateURL & Link ToolsBuild a URL with query parameters from a simple table of names and values.
Runs entirely in your browser. Your input is not uploaded to Ovatly or anywhere else.
- 1Enter the base URL, with or without parameters it already has.
- 2Add one row per parameter: a name on the left, its value on the right.
- 3Leave encoding on unless you have a specific reason to place values exactly as typed.
- 4Copy the finished URL from the result box.
Base: https://example.com/search Rows: q = red shoes, page = 2 Result: https://example.com/search?q=red+shoes&page=2
- With encoding on, spaces in values become + and characters like & and # are escaped, which is the standard behavior for query strings.
- Parameters already on the base URL are kept, and new rows are appended after them.
- With encoding off, values go in exactly as typed; a value containing & will be read as a new parameter by the receiving site, which is occasionally what testers want and usually a mistake.
The part of a URL after the question mark, made of name=value pairs joined by ampersands. It carries search terms, page numbers, tracking codes and similar data.
About this tool
The Query String Builder assembles URLs with parameters from a simple table of names and values, instead of typing question marks and ampersands by hand. It is built for campaign links, search URLs, API testing and support links where one mistyped character silently breaks the tracking or the search.
