Canonical URL Helper

The same page is often reachable through several URLs — with and without www, with UTM parameters, with or without a trailing slash. Pick your preferred rules once and clean a single URL or a whole list, then copy the canonical link tags.

Runs entirely in your browser. Your input and files are not uploaded to any server.

How to use

  1. Paste one or more URLs, one per line.
  2. Choose your rules for protocol, www, trailing slash and query parameters.
  3. Copy the cleaned URLs or the generated <link rel="canonical"> tags.

Examples

Campaign link

http://Example.com/shoes/?utm_source=mail&size=42 → https://example.com/shoes/?size=42

Default document

https://example.com/blog/index.html → https://example.com/blog/

Check it yourself: open your browser’s developer tools, select the Network tab and use the tool. Your file never appears in an upload request. Once this page is saved for offline use, you can also disconnect from the internet and keep working. Ads and anonymous visit statistics, when enabled, make their own requests, but they never receive your files or text.

Frequently asked questions

Which version should be canonical?

Any consistent choice works. Use the version your internal links, sitemap and redirects already use.

Is a canonical tag a redirect?

No. It is a hint to search engines. If an old URL should never be used, a 301 redirect is stronger.
