The Domain Extractor from URLs takes a list of links and maps every input entry to its extracted hostname. It removes the protocol, path, query string, fragment, port, and user information while keeping the original sequence, so row 4 in the result always belongs to row 4 in the input.
It is designed for SEO analysts, developers, security researchers, and marketers who work with URL lists from crawls, logs, backlink exports, or scraped pages. Duplicate domains stay in place instead of being grouped, and invalid entries remain visible as an invalid row so later results never shift unexpectedly.
All parsing happens in your browser using JavaScript, so nothing you paste is uploaded or retained. An optional setting removes the leading www from each extracted host. Summary statistics show total, valid, invalid, unique, and duplicate counts separately without changing the order of the results.
Features of Domain Extractor from URLs
- Extracts the host portion from each URL, stripping the protocol, path, query string, fragment, and port.
- Handles links that begin with http, https, or a bare www prefix, so mixed lists are parsed consistently.
- Preserves every row and every duplicate domain in exactly the position where its source URL appeared.
- Offers an optional remove-www setting so each extracted host can be normalised consistently.
- Ignores user information before an at sign in a URL so credentials never leak into the domain list.
- Shows the row number, original URL, and extracted domain together for an obvious input/output mapping.
- Keeps invalid URL rows visible and reports valid, invalid, unique, and duplicate summary counts above the table.
- Exports the same ordered mapping to CSV or XLSX, or copies it to the clipboard without sorting or deduplication.
How to use Domain Extractor from URLs
- Paste your list of URLs into the input box, one per line or separated by spaces.
- Decide whether to remove the leading www, merging www and non-www variants of the same domain.
- Read the table, where each row shows its input number, original URL, and matching extracted domain.
- Use the stats to see total, valid, invalid, unique, and duplicate counts without changing row order.
- Check invalid rows directly instead of guessing which later output belongs to which source URL.
- Copy the ordered mapping or export it to CSV/XLSX for reporting, review, or import elsewhere.
Benefits of Domain Extractor from URLs
- SEO analysts map every backlink or crawl URL to its referring domain without losing source positions.
- Developers extract hosts from log files while retaining the exact line that produced each result.
- Security researchers can inspect suspicious URL lists and see invalid entries rather than silently skipping them.
- Marketers audit tracked links while preserving campaign order and repeated destinations.
- Anyone reviewing a URL export gets a clear source-to-domain mapping instead of an untraceable list.
- Local processing keeps sensitive URLs, including internal endpoints, private to your own device.
A URL packs several pieces of information into a single string: a scheme, optional credentials, a host, an optional port, a path, a query string, and a fragment. When you only care about which site a link points to, all of that surrounding detail is noise. This tool isolates the host and discards the rest, so a long tracked link and a short bare URL to the same site both collapse to the identical domain.
The www prefix can be normalised without changing row order. Many sites are reachable at both example.com and www.example.com, but this tool still keeps every occurrence as its own row so you can trace each source URL. Disable the option when the literal www host matters to your analysis.
Because everything runs locally in your browser, your URL list is never uploaded, which matters when links include internal endpoints, signed URLs, or private analytics. The tool extracts the host rather than resolving it, so it does not know registrable-domain boundaries; if you need subdomain grouping, pair it with the Subdomain Extractor.
