Free Email Extractor — Find & Dedupe Emails from Any Text
Scraped a page, exported a CSV, or copied a messy contact list? Paste it here and the Email Extractor pulls out every valid email address, removes duplicates, lowercases them for consistency and counts the results. Because it runs entirely in JavaScript on your device, your contact lists and customer data never touch a server — which matters under GDPR and India's DPDP Act.

How Email Pattern Matching Works — Under the Hood
Email extraction uses a regular expression that mirrors the RFC 5322 "addr-spec" grammar: a local part (letters, digits, dots, underscores, plus signs), an @ symbol, a domain of dot-separated labels and a two-letter-plus TLD. Matches are collected, lowercased and pushed through a Set to remove duplicates — all in-memory, so a 10,000-line paste finishes in well under a second.
Frequently Asked Questions
Does this upload my data?
No. Extraction runs entirely in JavaScript inside your browser — your text never touches any server.
Can I extract emails from huge files?
Yes, up to your browser memory. For very large files, split them or paste in chunks.
Does it validate emails?
It checks the standard address pattern. For deliverability checks you still need a verification service.
