Free tool

Runs in your browser. Your text is not uploaded for processing. Use trusted offline software for secrets, especially when third-party advertising or browser extensions are active.

How to use this tool

Paste an absolute URL, a query beginning with ? or raw name=value pairs. URLSearchParams decodes form-query syntax, where + means a space. Results include ordered pairs and grouped values so repeated keys are retained. Fragments are excluded. No URL is requested or checked for accessibility.

A WORKED EXAMPLE

Try these values

?tag=php&tag=js&q=hello+world produces two tag values and q equal to hello world.

Common questions

Does my input leave this page?

The tool processes its input in your browser. It does not send the text to our server for calculation. If advertising is enabled, third-party ad scripts also run on the page; use a trusted offline tool for secrets.

Can I use the result in my project?

Yes. Check the example and limitations first, and test the output with the system that will consume it.
