Bare domains can hide inside links, email addresses and plain text, which makes them hard to list by hand.
Domain Extractor pulls domains from all three and can reduce them to their root domain.
How to use Extract Domains from Text
- Paste links, email addresses or bare domains into the input box.
- Turn on root-domain reduction to fold subdomains into their root, then sort or dedupe as needed.
- Copy the domain list, or download it as a .txt file.
Use cases
- Listing every domain referenced across a block of mixed text.
- Collecting the domains from a set of email addresses.
- Reducing a list of subdomains to their root domains.
Good to know
Domain Extractor takes hosts from links, the domain part of email addresses and bare domains in text, then optionally reduces each to its registrable root. Root reduction uses a limited public-suffix list, so common multi-part suffixes such as co.uk are handled while rarer ones may not be.
Frequently asked questions
Does it get domains from email addresses?
Yes. The part after the at sign in each address is included alongside domains found in links and plain text.
What does root-domain reduction do?
It folds a subdomain such as blog.example.com down to example.com so you see one entry per site.
Are suffixes like co.uk handled?
Common ones are, through a limited built-in list, so example.co.uk reduces correctly; very rare suffixes may not be recognised.
