Extract domains from URLs, emails, text, logs, and mixed input. Deduplicate hostnames, optionally normalize to registrable root domains, and export CSV, JSON, or TXT—processing stays in your browser.
Loading tool…
This Domain Extractor is built for bulk, mixed input—not a single-URL parser. Paste server logs, CRM exports, URL lists, HTML snippets, markdown, or notes that mix links and addresses in one field.
The scanner finds full URLs (including protocol-relative // links), markdown links, email addresses, JSON/HTML attributes, and dotted hostnames. IPv4 and IPv6 literals are skipped so lists stay hostname-focused.
Optional registrable-root mode rolls subdomains up to the domain you could register under a public suffix (the eTLD+1)—for example api.mail.google.co.uk → google.co.uk. Fast mode uses curated multi-part suffixes; Maximum accuracy loads the Public Suffix List (PSL) once in your browser. Export as CSV, JSON, or plain text.
For email-only lists, URL-only lists, or simple prose, use the focused extractors linked below—this page owns mixed and bulk workflows.
Paste mixed URLs, emails, logs, or text → deduplicated hostnames or root domains → CSV/JSON/TXT export in your browser.
Paste URLs, emails, server logs, CSV exports, HTML, or mixed notes—or upload a .txt/.csv/.log file (up to 2 MB). Pastes are capped around 500k characters.
Simple mode covers quick deduplication. Advanced adds registrable-root normalization, Fast vs PSL suffix mode, TLD filters, frequency view, and optional custom regex.
Sort A–Z or by frequency, filter by TLD, optionally validate hostnames, and group by registrable root when normalization is on.
Copy a newline list, or download TXT, CSV (optional count/root/TLD columns), or JSON. Clear the field when finished on a shared machine.
Input shapes covered by the bulk/mixed scanner on this page.
| Input | Examples | Result |
|---|---|---|
| URLs and protocol-relative URLs | https://…, //cdn.example.com | Hostname from each link |
| Email addresses | user@mail.example.com | Domain after @ |
| Server logs and CSV files | Access logs, spreadsheet exports | Hosts found in cells/lines |
| HTML and markdown | href, src, [text](url) | Linked hostnames |
| Hostnames and registrable domains | api.blog.example.co.uk | Hostname, or eTLD+1 when normalized |
Need only emails, only URLs, or only plain prose? Use the focused extractors in the comparison below.
How this tool treats DNS names versus registrable (eTLD+1) roots.
| Term | Meaning | Example |
|---|---|---|
| Hostname | Full DNS name as extracted | www.blog.example.com |
| Subdomain | Labels left of the registrable domain | www.blog |
| Registrable / root domain (eTLD+1) | Domain registrable under a public suffix | example.com |
| Public suffix / eTLD | Suffix you cannot register alone | .com, .co.uk, .github.io |
Enable Normalize to registrable domain to collapse subdomains; choose Fast or Maximum accuracy (PSL) for suffix rules.
Choose root-domain mode based on accuracy needs and offline use.
| Mode | Best for | Trade-off |
|---|---|---|
| Fast (curated list) | Everyday .co.uk, .com.au, and common multi-part TLDs | Works offline after page load; may miss rare provider domains |
| Maximum accuracy (PSL) | github.io, regional nic TLDs, unusual public suffixes | Downloads Public Suffix List once in-browser; slightly slower first run |
This page owns mixed/bulk input; focused pages stay format-specific.
| Tool | Input shape | When to use |
|---|---|---|
| Domain Extractor (this page) | Logs, emails, URLs, CSV, HTML, mixed text | Bulk paste; dedupe; root mode; CSV/JSON/TXT export |
| Extract Domain from Email | Email address lists | CRM or mailing-list exports only |
| Extract Domain from URL | Line-oriented URLs | Sitemap or URL list imports |
| Extract Domains from Text | Plain prose and snippets | Beginner text-only extraction |

Use this Domain Extractor for mixed URLs, emails, logs, and exports. Switch to a focused tool when the input is already a single format.
| Related tool | Use this tool when | Use related tool when |
|---|---|---|
| Extract Domain from Email | Your paste mixes emails with URLs, logs, or CSV columns and you need bulk dedupe plus export. | You only have an email address list and want a focused email-domain workflow. |
| Extract Domain from URL | Input includes emails, HTML, logs, or messy multi-format text alongside links. | You have a clean URL list (one link per line) and only need domain/hostname cleanup. |
| Extract Domains from Text | You need hostnames from mixed technical pastes with CSV/JSON export and PSL root mode. | You only have plain prose or notes and want a simple registrable-domain list. |
URL-shaped input and ASCII punycode (xn--…) work reliably. For IDN, paste the canonical https link or punycode hostname.
Switch to Maximum accuracy (PSL) under Advanced so registrable roots match the Public Suffix List.
Uploads are capped at 2 MB and pastes around 500k characters; split very large logs and process in chunks.
For email-only, URL-only, or plain-text-only lists, the focused extractors are simpler—keep this page for mixed/bulk work.
Paste logs, CRM exports, or URL lists into the box—the scanner finds http(s) links, protocol-relative // URLs, email addresses, and bare hostnames. Results are deduplicated; turn on Normalize to registrable domain if you want one root per site (for example api.mail.google.co.uk → google.co.uk).
A hostname is the full DNS name (www.blog.example.com). The registrable domain is what you could register under a public suffix—often called the eTLD+1 (example.com, example.co.uk). This tool can show hostnames as extracted, then optionally roll subdomains up to that registrable root.
Mixed text: bare URLs, protocol-relative links, markdown links, email addresses, HTML/JSON attributes, server logs, CSV exports, and plain hostnames. That mixed/bulk coverage is what this page is for.
Registrable-root mode strips subdomains and returns the domain you would register (eTLD+1). For example, blog.company.co.uk becomes company.co.uk when suffix rules match. Use Fast mode for common multi-part TLDs or Maximum accuracy (PSL) for edge cases like github.io.
Yes—paste addresses here as part of mixed input. If your file is email-only, Extract Domain from Email is the focused alternative; use this Domain Extractor when emails are mixed with URLs or logs.
Export as CSV (optional count, root, and TLD columns), JSON, or plain newline-separated TXT. CSV counts help prioritize domains that appeared most often.
Yes when the input is URL-shaped or uses ASCII punycode labels (xn--…). The browser’s URL parser normalizes hostnames like the address bar. Raw Unicode labels only in prose may be missed—prefer pasted links or punycode.
The extractor skips IPv4/IPv6 literals, drops candidates that fail hostname validation, and ignores strings that never look like a URL, email, or dotted hostname. Enable Maximum accuracy (PSL) under Advanced for unusual TLDs and provider domains like github.io.
Fast mode uses a curated set of multi-part suffixes (e.g. .co.uk, .com.au) for speed and offline use. PSL mode downloads public-suffix data and matches the longest registrable suffix—better for edge cases. Both modes stay in your browser.
By default www can be kept as part of the hostname. Options let you include or strip www, dedupe www vs non-www, and normalize case.
No. Parsing, filtering, and export run in your browser tab. Nothing is sent to EverydayTools servers for this tool. Optional PSL mode only fetches a static suffix file from the site CDN.
Uploads are limited to about 2 MB (.txt/.csv/.log). Pastes are capped around 500k characters so tabs stay responsive. Split very large files if the UI warns you.
Use Extract Domain from Email for email-only lists, Extract Domain from URL for clean URL lists, and Extract Domains from Text for plain prose. Stay on this Domain Extractor for mixed/bulk input with dedupe, root mode, and multi-format export.
Domain Extractor (/domain-extractor) runs in your browser when supported—pasted text and uploads are not sent to EverydayTools servers for extraction.
Hostname validation follows browser URL parsing and conservative hostname rules. Registrable-root output depends on Fast curated suffixes or Public Suffix List (PSL) mode as selected.
Results are for planning and analysis. Verify critical allowlists or security decisions against authoritative DNS and policy sources.
