Domain Extractor

Domain Extractor is a free online tool that extracts domain names from URLs, text, email addresses, and file uploads, processing everything locally in your browser without requiring sign-up or installation.

What is Domain Extractor?

Domain Extractor is a web-based utility that scans input content—such as pasted text, uploaded files (TXT, CSV, HTML, MD), or email addresses—and identifies all valid domain names. It outputs a clean, deduplicated list of domains, optionally normalized to root domains (e.g., blog.google.com → google.com). All processing happens client-side using JavaScript; no data is sent to a server, ensuring privacy. The tool is developed and hosted at domainextractor.org.
