Free URL to Domain Extractor

How to Extract Domains from URLs in 3 Steps

1

Paste URLs or text

Paste a URL list, a backlink export, an email, or HTML. Every http and https link is found, plus bare domains like example.com/page, and all of it runs in your browser.

2

Pick the output and review

Choose root domain, full hostname, or hostname without www. Each result shows how many URLs it covers, with IP addresses, local hosts, and platform subdomains labeled.

3

Copy or download

Copy the plain list, download a CSV with domain, count, and an example URL, or build a disavow file with one domain: line per site.

What Is the Public Suffix List, and Why "Last Two Labels" Breaks

The shortcut is only right when the suffix is a single label, like com. The list also changes as new entries are added, so this tool uses the copy bundled with the open source tldts library; a suffix added very recently may not be recognized until that copy is updated. Hosts whose ending is not on the list at all (an internal name like example.local, for instance) are still extracted when written as a full http(s) URL, and labeled so you can spot them.

Extract a Domain from a URL in JavaScript and Python

Both languages parse the hostname out of the box. The root domain needs a library that ships the Public Suffix List, which is where most hand-rolled code goes wrong.

JavaScript (browser or Node.js)

// Hostname: the URL parser built into browsers and Node.js
new URL('https://www.bbc.co.uk/news').hostname;  // 'www.bbc.co.uk'

// Root domain: needs the Public Suffix List (npm install tldts)
import { getDomain } from 'tldts';
getDomain('https://www.bbc.co.uk/news');                                  // 'bbc.co.uk'
getDomain('https://jane.github.io/blog');                                 // 'github.io'
getDomain('https://jane.github.io/blog', { allowPrivateDomains: true });  // 'jane.github.io'

new URL() throws on a bare domain like example.com/page, so add https:// first. tldts leaves platform suffixes out unless you pass allowPrivateDomains, which is what this tool's platform option switches.

Python

from urllib.parse import urlsplit
urlsplit('https://www.bbc.co.uk/news').hostname   # 'www.bbc.co.uk'
urlsplit('www.bbc.co.uk/news').hostname           # None: add the scheme first

import tldextract  # pip install tldextract
ext = tldextract.extract('https://www.bbc.co.uk/news')
f'{ext.domain}.{ext.suffix}'                      # 'bbc.co.uk'

private = tldextract.TLDExtract(include_psl_private_domains=True)
p = private('https://jane.github.io/blog')
f'{p.domain}.{p.suffix}'                          # 'jane.github.io'

By default tldextract fetches the latest Public Suffix List on first use and caches it. For an IP address the suffix comes back empty, so check ext.suffix before joining the parts.

Clean Domain Lists, Then Links You Can Measure

The extractor tells you which sites a list of links points to. Flyn short links tell you what happens when people click the links you share.
