Query String Parser

Paste a full URL or a bare query string and see its parameters broken out into a readable table, with values automatically URL-decoded. Great for debugging links, UTM tags and API calls.

Runs in your browser — your files never leave your device

Reading URL query parameters

The query string is the part of a URL after the ? — a set of key=value pairs separated by &. Parsing it into a table makes it easy to inspect UTM campaign tags, API parameters, or tracking values when debugging a link.

Paste a full URL or just the query string; the tool strips the fragment, splits the pairs, and URL-decodes each value so you see the real content. It all runs in your browser.

Frequently asked questions

Can I paste a whole URL?

Yes. Everything before the ? and any # fragment is ignored, so a full URL works fine.

Are the values decoded?

Yes. Percent-encoding and + signs are decoded so you see the real values.

Is my URL sent anywhere?

No. Parsing happens entirely in your browser.
