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.
WhatsApp Link Generator
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.
- A wa.me link with a pre-filled message
- QR code as PNG or SVG, with your colours and logo
- Bulk links from up to 5,000 numbers
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.
- Adds the country code and removes the leading 0
- Removes duplicates and flags bad numbers, with the reason
- Pastes from Excel and downloads a clean CSV
WhatsApp Broadcast List Maker
Paste a list of names and phone numbers, or open a CSV file. The tool cleans the numbers, removes duplicates and cuts the list into batches that fit a WhatsApp broadcast list, as contact files you can add to your phone. Free, no login, and your list never leaves your browser.
- Cuts a list into batches of 256, the size of one broadcast list
- Cleans numbers, removes duplicates and keeps names
- Contact files for iPhone, Android and Google Contacts
