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
- Paste the URL you want to canonicalize.
- Toggle the normalization options you need.
- 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.
