How to Use the URL Normalizer

  1. Paste or enter your input into the text field.
  2. Configure any options (format, delimiter, encoding, or mode) using the controls above the output.
  3. The result updates instantly — no submit button required for most operations.
  4. Click Copy or Download to take the output to your next step.

Convert URLs to a single canonical form so you can deduplicate, compare, or store them reliably. The normaliser lowercases the scheme and host, removes redundant default ports (:80, :443), resolves . and .. path segments, and percent-encodes any unsafe characters that were left raw — all per RFC 3986.

How the URL Normalizer Works

Optional steps include sorting query parameters alphabetically, removing the trailing slash on the path, and stripping empty fragments. The result is a URL byte-for-byte identical for any equivalent input — perfect for cache keys, deduplication, and SEO canonicalisation.

Frequently Asked Questions

Why normalize URLs at all?

Two URLs that look different (HTTP://Example.com:80/a/./b vs http://example.com/a/b) point to the same resource. Normalising them produces a canonical form so caches, deduplication tools, and analytics treat them as one entry.

Does sorting query parameters change the response?

For most servers it doesn’t — query strings are key/value bags. A small number of legacy systems care about parameter order; turn off the sort option in those cases.

How are dot segments resolved?

Per RFC 3986 §5.2.4: . is removed, .. pops the previous path segment, and trailing dots that imply a directory are kept. So /a/b/../c becomes /a/c.

Is the URL sent anywhere for normalization?

No — the URL is parsed by the browser’s URL constructor and rebuilt locally. Nothing is uploaded.
