Why use a query string builder?

It prevents small encoding mistakes when building links for search pages, campaign tests, API examples, or documentation.

How should I enter values?

Use one key=value pair per line. If a line has only a key, the value is treated as empty. The tool encodes spaces and non-English text for the URL.

Can I add it to an existing URL?

Yes. Paste a base URL and the tool appends the encoded query using ? or & depending on whether the URL already has parameters.

Are the parameters uploaded?

No. The query string is built inside your browser. berryfy does not receive or store the values.

Build URL parameters without encoding mistakes

Query strings are easy to break by hand when values contain spaces, emoji, Korean, Japanese, ampersands, or equals signs. This builder encodes each key and value so the final link is ready to paste.

Enter one key=value pair per line and optionally add a base URL. The output shows both the encoded query and the full URL so you can confirm the result before copying.

The builder runs in the browser. Draft campaign URLs, search links, test parameters, and internal examples are not uploaded.
