Query string builder

Create URL parameters and generate an automatically encoded query string.

Base URL (optional)

Query string

?q=herramientas+online&pagina=1

Full URL

https://ejemplo.com/buscar?q=herramientas+online&pagina=1

How it works

Add key-value pairs. The tool uses URLSearchParams to encode the parameters correctly and can append them to a base URL.

Are spaces and special characters encoded?

Yes. The parameters are encoded using the standard URLSearchParams behavior.

Can I generate only the query string?

Yes. The tool shows both the query string and the full URL when you provide a base URL.
