Extract Canonical URLs
Extract canonical link href values from pasted HTML head snippets without fetching, crawling, or uploading pages.
0 / 30,000 characters. No upload, storage, or account required.
Canonical URL extraction workflows
Use canonical URL extraction when canonical tags are buried inside pasted source and need a quick list for SEO review or migration checks.
Check canonical details
Pair this with Canonical Tag Checker when you need pasted-input diagnostics for one HTML snippet.
Review international tags
Use Extract Hreflang Tags when the same head snippet includes alternate language annotations.
Clean copied URLs
Send copied output to URL Parser, Remove Duplicate Lines, or Sort Lines.
What this tool does
Extract Canonical URLs finds rel=canonical href values in pasted HTML, removes duplicates, shows source-line context, and runs locally in your browser.
Common use cases
Extract rel=canonical href values from pasted HTML head snippets, templates, copied page source, and migration exports before SEO QA, canonical inventory, or template documentation.
Use Extract Canonical URLs when you are working with copied API payloads, logs, encoded values, config snippets, identifiers, or debugging data and need a quick browser-local check before pasting the result into docs, tickets, tests, or another developer tool.
How to use it
- Paste HTML head snippets, copied page source, templates, CMS fragments, or migration exports that contain canonical link tags.
- Choose whether duplicate canonical URLs should be removed and whether HTML entities should be decoded.
- Review source lines, then copy the clean canonical URL list for SEO QA, migrations, or template documentation.
Example workflow
Copy a small payload or encoded value from an API response, request URL, log line, or config file. Run the focused check here, confirm the output is readable, then continue with related developer data tools such as validation, formatting, decoding, timestamp conversion, or CSV/JSON conversion.
Privacy note
Canonical URL extraction runs locally in your browser. ClearUtils does not upload, store, fetch, crawl, render, execute, or log the HTML text you paste.
FAQ
Does Extract Canonical URLs crawl my site?
No. It only reads the HTML text you paste in your browser. It does not fetch URLs, crawl pages, upload snippets, render code, or store input.
What canonical tags can it find?
It finds common link tags where rel contains canonical and extracts the href value, including quoted and entity-encoded URLs.
Is this the same as the Canonical Tag Checker?
No. This extractor focuses on copying canonical URL lists from pasted markup, while the checker gives diagnostics for a single HTML snippet.
