The Email Extractor scans any block of text and pulls out all email addresses into a clean, deduplicated list. Whether you are mining contact information from a web page, processing a database export, cleaning up a mailing list, or auditing where email addresses appear in a document, this tool saves you from tedious manual searching. Paste your text, click Extract, and get a unique list of email addresses with a count — ready to copy in one click. All processing runs client-side in your browser, so your text is never uploaded to any server. This makes it safe for sensitive documents, customer data, and proprietary content.
About Email Extractor
Manually finding email addresses in large blocks of text — from web pages, documents, exported data, or email threads — is time-consuming and error-prone. This tool uses a regular expression pattern to identify strings that match standard email address formats (local-part@domain.tld) and returns a deduplicated, sorted list. It handles emails embedded in HTML, CSV, JSON, and plain text. The extraction runs entirely in JavaScript in your browser, meaning your data stays on your device and is never transmitted to any external service. This privacy-first approach makes it suitable for processing customer lists, internal documents, and other sensitive materials.
How to Use Email Extractor

- Click Extract emails. A unique list of found email addresses appears with the total count.

Technical Details
The tool uses a regular expression pattern that matches standard email address formats: a local part containing alphanumeric characters and common special characters (., +, -, _), followed by @, followed by a domain with at least one dot. While no regex can perfectly match the full RFC 5322 email specification, the pattern used here covers the vast majority of real-world email addresses. Results are deduplicated using a JavaScript Set and presented in the order they first appear. Processing is O(n) in text length, making it fast even for large inputs.
Conclusion
The Email Extractor is a fast, privacy-respecting tool for pulling email addresses out of any text. With automatic deduplication and one-click copying, it streamlines contact extraction workflows — all running entirely in your browser.
