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.
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.
How to use Query String Parser

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.
