Query String Cleaner
A query string cleaner takes a URL weighed down with tracking and analytics parameters and rebuilds it as a clean, canonical address. Paste a link with a trailing ?utm_source=…&gclid=… tail and the tool lists every parameter, flags the ones that add no value, and serialises a tidy URL you can copy. Bloated query strings split link equity across duplicate URLs, pollute analytics, and make audits harder to read, so trimming them is a quiet but real win for technical SEO.
This tool is free and runs entirely in your browser. It parses with the same logic a browser uses, strips known tracking keys such as the UTM set, gclid, fbclid, and msclkid, removes empty values and duplicate keys on request, and never sends the URL anywhere.
🔒 Private: everything runs in your browser. Nothing you paste is uploaded.
How to use the query string cleaner
Paste a full URL or a raw query string, toggle the cleaning options, and the parameter list and cleaned URL update on every change. Removed parameters stay visible with a struck-through label so nothing disappears silently.
Strip the tracking parameters that fragment your URLs
Campaign tags like utm_source, utm_medium, and utm_campaign, plus click identifiers such as gclid, fbclid, msclkid, gbraid, and wbraid, never belong in a canonical URL. They create endless variants of the same page, dilute link signals when those tagged URLs get shared and linked, and clutter crawl reports. The tool recognises the common tracking set and strikes those keys out by default, so the address you copy is the clean version a search engine should index rather than the campaign-tagged one a marketer pasted into a newsletter.
Drop empty values and duplicate keys for a true canonical
Two URLs that differ only in parameter order, an empty ?size= value, or a repeated key are treated as distinct addresses by crawlers even though they serve identical content. Removing empty values eliminates the noise that templating bugs leave behind, and collapsing duplicate keys to the first occurrence stops near-identical variants from competing with each other. Pair these toggles with alphabetical sorting and the same set of parameters always produces one stable, predictable string, which is exactly what a canonical tag or an internal link should point at.
Keep the parameters that actually change the page
Not every parameter is junk. Pagination, filters, search terms, and product variants genuinely change what a page returns, and stripping them would break the URL. The cleaner only removes keys it can justify, tracking, empty, or duplicate, and leaves everything else untouched, so a faceted-navigation link such as ?category=boots&sort=price survives intact. Review the parameter list before copying: anything still shown without a struck-through label is a parameter the tool judged meaningful, and you stay in control of the final result.
Query string cleaner frequently asked questions
Q1What is a query string in a URL?
A query string is the part of a URL after the question mark, made of key=value pairs joined by ampersands, such as the section reading utm_source=newsletter&id=42. It passes data like search terms, filters, or campaign tags to a page. Some parameters change what the page shows, while tracking parameters only feed analytics and are safe to remove from a canonical address.
Q2Which tracking parameters does this tool strip?
It removes the full UTM set, utm_source, utm_medium, utm_campaign, utm_term, and utm_content, along with click identifiers including gclid, fbclid, msclkid, gbraid, wbraid, mc_eid, igshid, yclid, and the generic ref. These keys only feed analytics or ad platforms, so they never belong in a canonical URL. Parameters that genuinely change the page, such as filters or pagination, are always kept.
Q3Does cleaning the query string affect SEO?
Yes, in a helpful way. Bloated and inconsistent query strings create multiple URLs for one piece of content, which splits link equity and confuses crawlers about which version to index. A clean, canonical URL with only meaningful parameters consolidates those signals onto a single address. The cleaner gives you that canonical string to use in canonical tags, internal links, and sitemaps.
Q4Is my URL sent to a server?
No. The entire tool runs as client-side JavaScript in your browser, parsing and rebuilding the URL locally with no network request at any point. Nothing you paste is uploaded, logged, or stored, and the tool keeps working offline once the page has loaded. That makes it safe to clean internal, staging, or confidential URLs without exposing them.
Q5Will it break a URL that needs its parameters?
No, because it only removes parameters it can justify: known tracking keys, empty values, and duplicates, and each removal is shown with a struck-through label. Functional parameters like search queries, filters, pagination, and product variants are kept untouched. Review the parameter list before copying, and if a meaningful parameter ever looks at risk you can simply turn off the relevant toggle.
