Canonical Tag Generator

Name the one true address for any page. Type the canonical URL to get a paste-ready tag plus a 6-point validity check and duplicate-type verdict.

Fill this to detect self-referencing, variant and cross-domain setups.

Generated tag

<!-- Your tag appears here - type the canonical URL above -->

Validity checks

    0 / 6
    Checks passed

    URL length

    Technical Specifications

    Exactly what the tag contains and what the checks verify.

    Element Rule
    Tag format link rel="canonical" with an HTML-escaped absolute href, placed once in the page head
    Absolute URL Must start with http:// or https://; relative paths are rejected, never emitted
    Scheme https preferred; http passes the absolute check but fails the scheme check
    Host casing Hosts are case-insensitive, so uppercase letters are flagged for cleaning
    Fragments and spaces Hash fragments are never sent to servers and must go; spaces break the URL
    Signal strength Canonical is a hint, not a directive; conflicting signals may overrule it
    Processing location 100% client-side JavaScript in your browser memory; nothing is uploaded

    Features

    ✔️

    6-Point Checklist

    Duplicate Verdicts

    🔒

    Local Device Privacy

    Everything runs in the page with plain JavaScript. Drafts never leave your device.

    How to Use the Canonical Tag Generator

    1. Type the canonical URL: the single address that should rank.
    2. Optionally add the page URL carrying the tag for a setup verdict.
    3. Fix anything the validity checks flag, or press Clean URL.
    4. Click Copy Tag or Download .html.
    5. Paste the tag into the page head, exactly once per page.

    Where Duplicates Come From

    Most duplicates are accidents of plumbing: tracking parameters, sort and filter variants, www versus bare domains, http versus https, and trailing-slash splits each mint a new address for the same content. Every variant dilutes ranking signals unless one address is crowned canonical.

    Crown one address per page set

    Point every variant at the cleanest version and give that version a self-referencing tag as well. For syndicated copies, the copy points across domains at the original. Coordinate the wider crawl setup with the Robots.txt Generator and the discovery file from the Sitemap XML Builder.

    Honest limitations

    A canonical is a hint Google may ignore when page content differs sharply or signals conflict, such as a canonical pointing at a redirected or noindexed address. It also cannot gate access or hide private pages. Treat green checks as a valid vote, not a guaranteed outcome.

    Privacy and Client-Side Security

    Privacy Guarantee: All tag building occurs locally inside your browser. Your addresses are never transmitted, stored, or recorded on remote servers.

    Many online generators send your drafts to a server for processing. TinyToolzz takes a different approach: every step runs in the page itself with plain JavaScript string operations.

    Because nothing is uploaded, there is no waiting, no account, and no copy of your URL structures retained anywhere. Your addresses exist only in the tab memory and are discarded when you close the page or click Clear.

    Frequently Asked Questions

    What is a canonical tag?
    A canonical tag is a link element in the page head, such as link rel=canonical href=https://example.com/page/, that names the authoritative version of the page. It tells search engines which address to index when duplicates exist, consolidating ranking signals onto one URL.
    What is a self-referencing canonical?
    A self-referencing canonical points the page at its own address. It is the recommended default on every indexable page because it defends against tracking parameters, case variants and scraper copies without changing anything about the page itself.
    When should I use a canonical instead of a redirect?
    Use a canonical for near-duplicates that must stay live, like sorted, filtered or tracked variants of one page. Use a 301 redirect when a page has permanently moved, and noindex when a page should leave the index entirely.
    Are cross-domain canonicals allowed?
    Yes. A republished copy may point its canonical at the original on another domain, passing signals back to the source. The original must not point back, and both pages need crawlable, indexable content for the hint to be honored.
    What are the most common canonical mistakes?
    Relative URLs, leftover hash fragments, mixed http and https, uppercase hosts, and pointing at redirected, missing or noindexed pages all weaken or void the signal. Keep one absolute, clean, crawlable canonical per page.
    Is my URL data uploaded to a server?
    No. All tag building happens locally in your browser with JavaScript. Your addresses are never transmitted, stored or logged anywhere. Closing the tab or clicking Clear removes everything immediately.
