About Canonical Tag Helper

Canonical tags tell search engines which version of a URL is the master, preventing duplicate-content dilution from tracking parameters, www, and trailing-slash variants. Canonical Tag Helper on TheToolss normalizes a URL with the options you choose — force HTTPS, strip query strings, remove www, lowercase the path, drop the trailing slash — then outputs a ready rel="canonical" link tag. Paste your page URL, tune the rules, and copy the tag into your <head>. It runs entirely in your browser — free, private, and no signup.

How to use Canonical Tag Helper

  1. Paste the page URL.
  2. Choose normalization options (HTTPS, no query, no www, etc.).
  3. Copy the generated rel=canonical tag into your <head>.

Frequently asked questions

Is the Canonical Helper free?
Yes. Generate canonical tags free on TheToolss, no signup.
Where does the canonical tag go?
Place the <link rel="canonical"> inside the <head> of the page it refers to. It should point to the preferred URL.
Should a canonical URL be self-referencing?
Usually yes. Most pages should canonicalize to their own clean URL; duplicates and parameter variants point to that master.
Should I strip query strings?
Strip tracking parameters (like utm_*), but keep parameters that change page content, such as product variants or pagination.
Is my URL uploaded?
No. Normalization happens locally in your browser.
