URL to Domain Converter

Page details

Extract clean root domains from up to 10,000 URLs, resolved with the Public Suffix List so .co.uk and .com.au come out right. Runs in your browser. Free.

Extract clean root domains from thousands of URLs in your browser.

Built for the crawl exports, log files and backlink lists you already have

Nothing to install and nothing to configure first. The parsing happens in the page you are already looking at.

Paste them one per line or mixed into any text, upload a .txt, .csv or .log file, or read them from your clipboard. Smart extraction pulls the URLs out of crawl exports and raw HTML, up to 10,000 at a time.

Strip www, roll subdomains up to the root, remove duplicates, force lowercase, keep the protocol, path, query or fragment, include or exclude whole TLDs, and choose whether hosting suffixes such as github.io count as domains in their own right.

Every hostname is parsed against the Public Suffix List without leaving your device. Review the domains list or the details table, then copy it or export TXT, CSV, Excel or a disavow file ready for Search Console.

Taking the last two labels of a hostname is right often enough to feel safe. These are the cases where that assumption breaks, and what the Public Suffix List returns instead.

The suffix is itself two labels, so the naive method returns the suffix and nothing else — a string nobody can register.

The same trap in a different country. Australia's commercial suffix has two labels, so the site name is dropped entirely.

myproject.blogspot.com with private suffixes on, blogspot.com with them off

blogspot.com as a private suffix, com as an ICANN one

blogspot.com is a private suffix: every account gets a name under it. Switch private suffixes on when each subdomain is really a separate site.

No difference here, and that is the problem — the easy case is what convinces people the naive method works everywhere.
