Does it keep subdomains?
Yes. The domain is extracted as written, so www.example.com and example.com stay separate. Remove the www. part yourself if you want them merged.

About the Domain Extractor
Lists of links from emails, spreadsheets and reports often repeat the same site many times, and the full addresses are longer than you need. Extracting just the domain names gives a clean list for audits, outreach, or blocklists.
The extractor finds both full links and bare domain names, lowercases them, removes duplicates and sorts the result. Review the list before using it, because the pattern matches anything shaped like a domain.
FAQ
Domain Extractor — frequently asked
Will it pick up email addresses?
Yes, the domain part of an address is matched. Remove email addresses first if you only want websites.
Why did a file name appear in my list?
The pattern matches any word with a dot and a letter ending, such as report.pdf or config.yaml. Delete those lines from the output.
Does the tool visit the domains?
No. It only reads the text you paste. It never connects to the listed domains.
Can it handle very long lists?
Yes, though very large pastes can slow down the browser. Split a huge file into batches of a few thousand lines.
Is my text stored?
No. The text is processed in your browser and nothing is saved or sent.
