Canonical URL Generator

Normalize a URL and generate a clean <link rel=canonical> tag to avoid duplicate content issues.

https://example.com/Page?id=42%2F

Output

Paste any URL to normalize it — lowercase the host, strip common tracking parameters, and remove trailing slashes — then get a ready-to-use canonical link tag to prevent duplicate content problems in search engines. Normalization happens entirely in your browser.

How to use

  1. Paste the URL you want to canonicalize.
  2. Toggle the normalization options you need.
  3. Copy the generated canonical link tag into your page's <head>.

Frequently asked questions

Why use a canonical tag?
A canonical tag tells search engines which version of a page is the primary one when the same or similar content is reachable through multiple URLs.
Which tracking parameters get stripped?
Common parameters like utm_source, utm_medium, gclid, fbclid, and similar tracking IDs are removed when the option is enabled.
Should the canonical URL include a trailing slash?
Either is fine as long as you're consistent; this tool lets you optionally remove trailing slashes to match your site's convention.
