Free WhatsApp tools and browser extensions
Small, free tools for WhatsApp outreach and lead generation. Use them right here in your browser or install them as a browser extension, and move up to the LeadTrapper Windows app when you need to work with a whole list.

Type a WhatsApp number and, if you like, a message. You get a wa.me link and a QR code that never expires, ready to copy, test and download. Free, no login, and everything happens in your browser.

WhatsApp Number Formatter
Paste or open a list of phone numbers. The tool puts each one in the international E.164 format WhatsApp needs, removes duplicates, flags numbers that cannot be right, and gives you a clean CSV. Free, no login, and your list never leaves your browser.

Need to work with a whole list?
The free tools handle one link, one code or one page at a time. LeadTrapper for Windows checks which numbers on a list are on WhatsApp, sends personalised messages with calculated delays, and can build the list from Google Maps. If you use Claude, some of these tools also work inside it as free Claude connectors.
