An email extractor is a tool that automatically finds and extracts email addresses from any block of text. Instead of manually searching through documents, web pages, or files, this tool instantly identifies all valid email patterns and presents them in a clean, usable list.

This free online email extractor uses pattern matching to find email addresses in any text. It's perfect for building mailing lists, organizing contacts, or extracting data from documents—all without installing any software.

How Email Extraction Works

The tool uses a regular expression (regex) pattern to identify valid email addresses:

[a-zA-Z0-9._%+-]+@[a-zA-Z0-9.-]+\.[a-zA-Z]{2,}

This pattern matches standard email formats: local part @ domain . TLD

Best Practices

Verify before using: Extracted emails may include old or invalid addresses—verify before sending.
Respect privacy: Only use emails you have permission to contact. Respect opt-out requests.
Check duplicates: Enable "Remove duplicates" to get a clean list without repeated addresses.
Validate format: While the tool finds email patterns, some may be incorrectly formatted or fake.

Frequently Asked Questions

Is my data secure?

Yes! All processing happens locally in your browser. Your text is never sent to any server, ensuring complete privacy.

Can I extract from PDFs or images?

This tool works with text. For PDFs, copy the text first. For images, use OCR software to extract text, then paste it here.

Does this validate if emails are real?

No—this tool finds email-formatted strings. It doesn't verify if the mailbox exists or can receive messages. Use email validation services for that.
