Use this URL Canonicalizer to normalize a full URL into a cleaner and more stable form by trimming spaces, lowercasing the hostname, removing default ports, collapsing duplicate slashes in the path, sorting query parameters, and optionally removing a trailing slash from non-root paths. It is useful for deduplication, URL comparison, cleanup workflows, and debugging links that look different but should resolve to the same structure.
