Extract email addresses and HTTP/HTTPS web links from text into separate lists. Remove exact duplicates, copy or download TXT, with all processing on your device.
Your text is never uploaded to any server; all analysis is completed locally in your browser. No account, dependencies, online address checks or input storage are used. Results remain plain text and links are never opened automatically.
The extractor recognizes practical ASCII addresses with an unquoted local part up to 64 characters, valid dot-separated domain labels and a 2–63-letter final domain suffix. Plus addressing is supported. Quoted local parts, internationalized email addresses, punycode final suffixes, IP-literal domains and local-only addresses are outside its scope. This is not a complete RFC email parser.
Links must begin with http:// or https://. Bare domains, www-only links, mailto and FTP links are not extracted as web links. Browser URL parsing checks basic structure without contacting the destination. Original spelling, Unicode paths, query strings and fragments are retained; HTML entities and percent escapes are not decoded.
Common trailing prose punctuation and unmatched closing parentheses, brackets or braces are removed from web links. Balanced closing characters are retained. Trailing domain periods are removed from emails. This heuristic can remove punctuation that was part of an intended URL, and adjacent comma-separated links without whitespace can merge. Separate addresses and links with spaces or line breaks and review results. Exact duplicate matching is case-sensitive and performs no URL normalization; turning it off preserves every occurrence.
Extraction does not verify mail delivery, domain registration, website availability or safety. Nothing is contacted or opened. Emails appearing inside URL text may also appear in the email list. Do not treat the results as validation.
Input is limited to 200,000 UTF-16 text units and each URL candidate to 8,192 units. Exceeding a limit returns an error without partial results or truncation. Clear empties the text and results while preserving the duplicate option. Copy and TXT downloads contain only the selected list, one entry per line. No text is saved in browser storage.
