Which parameters count as tracking?

The utm_ family plus common click identifiers such as gclid, fbclid and msclkid. Every change made is listed underneath, so nothing is removed silently.

Is a normalised URL guaranteed equivalent?

Not always. Some servers treat a trailing slash as significant, and a few care about parameter order. Every change is optional for that reason.

About this tool

Rewrites a URL into a canonical form: lowercased host, default port removed, tracking parameters stripped, optional sorting of the query. Useful for deduplicating links and for comparing two URLs that point at the same resource.

Limitations

Normalisation is textual. Two URLs that normalise identically can still serve different content.
