About URL to Domain Extractor Tool

What is the URL to Domain Extractor?

The URL to Domain Extractor quickly pulls domains out of any pasted text or list of URLs. It's ideal for building allow/deny lists, cleaning marketing datasets, auditing backlinks, or normalizing logs before analysis.

How It Works

1. Paste text that contains one or more URLs.
2. Choose your options (keep subdomains, remove duplicates, lowercase, sort, add https://).
3. Click Extract Domains and copy the results.

Options

• Include subdomains: Output the full host (e.g., blog.example.co.uk) instead of the registrable root (e.g., example.co.uk).
• Remove duplicates: Output each domain only once.
• Convert to lowercase: Normalize casing for consistent lists.
• Sort results (A to Z): Alphabetize the final output for easier scanning and diffing.
• Add https://: Prepend https:// to each domain for quick, clickable links.

Key Features

1. Accurate Extraction: Parses URLs from messy text, query strings, and fragments.
2. Smart Root-Domain Mode: Collapses to the registrable domain (e.g., example.co.uk) for cleaner deduplicated sets.
3. Subdomain Preservation: Toggle on when subdomain granularity matters (e.g., cdn.example.com vs shop.example.com).
4. One-Click Cleanup: Lowercase, dedupe, sort, and add https:// in a single pass.

Common Use Cases

• SEO & Backlink Audits: Distill long URL lists into unique domains.
• Security: Build allow/deny lists from logs or reports.
• Marketing: Normalize link exports from campaigns and analytics.
• Data Hygiene: Standardize domains before joining or deduping datasets.
