See inside any query string
Long URLs stuffed with parameters are hard to read at a glance — campaign links, filtered product pages, and API
endpoints all pile key-value pairs after the question mark. This extractor pulls them apart: it separates the base
URL from the query string and lists every parameter and its decoded value in a tidy table, so percent-encoded
pieces like %20 read as real spaces.
It's especially handy for auditing UTM tracking on marketing links, debugging why a filtered page isn't behaving, or documenting the parameters an endpoint accepts. Repeated parameters are each shown on their own row, so nothing is hidden.

Frequently Asked Questions
What does the URL parameter extractor do?
It splits a URL into its base and query parameters, listing each key and value in a clean table. It decodes percent-encoding so values are human-readable.
Does it handle repeated parameters?
Yes. If a parameter appears more than once, each occurrence is listed separately, which is common with filters and multi-select query strings.
Is it useful for UTM tracking?
Very. Paste a campaign URL and instantly see utm_source, utm_medium, utm_campaign, and any other tracking values broken out and decoded.
Is this tool free and private?
Yes. Parsing runs in your browser — nothing is uploaded or stored.
