URL Domain Extractor
Turn a list of URLs, a log excerpt or any text into a clean list of domains. The extractor finds every web address, including bare domains, and gives you the full host name, the registrable domain (such as example.co.uk) or just the top-level domain, with “www.” removed and duplicates collapsed into a count.

URL Domain Extractor FAQ
What is the registrable domain?
The part of a host name someone registers: example.com for blog.example.com, and example.co.uk for shop.example.co.uk.
Is the registrable domain always correct?
For common domains and the usual country forms such as co.uk, com.au or com.bd, yes. Unusual suffixes from the full Public Suffix List, such as some hosting platforms, may be grouped differently.
Does it find URLs without https://?
Yes, bare domains such as example.org are recognised when separated by spaces or on their own line.
What happens to IP addresses?
They are listed as they are; they have no registrable domain.
How many URLs can I paste?
Up to about a megabyte of text, which covers tens of thousands of URLs.
Is anything sent?
No.
From URLs to domains
Many reports list individual pages when what you need is the sites behind them. A backlink export has thousands of URLs from a few hundred domains; a log file mentions the same hosts over and over. Reducing the URLs to domains, and counting them, makes such lists readable.
Which level to extract depends on the question. The full host name distinguishes blog.example.com from shop.example.com. The registrable domain groups everything owned by one registration, which is usually what matters for links and trust. The top-level domain shows the spread of countries or generic endings.
Finding the registrable domain is less simple than taking the last two labels, because many countries register names under second-level labels such as co.uk or com.bd. The extractor applies the common rules for those, which is right for the vast majority of real-world domains.
The tool reads URLs out of free text, so you can paste raw material directly. It ignores trailing punctuation, recognises bare domains, and keeps the first-seen order, which preserves any ranking in the original list.
