Click2App is a free Windows tool that lets you open phone numbers directly in WhatsApp with one click. It works from browsers and supported Windows applications, and you can choose between WhatsApp Web and WhatsApp for Windows. No copying, retyping or saving numbers as contacts. Click2App is lightweight, privacy-friendly, multilingual and actively maintained, with built-in updates, diagnostics and recovery options.

I built Click2App because something as simple as contacting a phone number through WhatsApp often takes more steps than it should. You see a number in a browser, document or application, copy it, open WhatsApp, paste or type it, and sometimes even save it as a contact first. Click2App removes those unnecessary steps. Hold your chosen key, click the phone number, and it opens directly in WhatsApp Web or WhatsApp for Windows. I wanted to keep it simple: lightweight, privacy-friendly and completely free. It works with several browsers and Windows applications, supports common European phone number formats and is available in five languages. Click2App is actively maintained, so feedback is very welcome. If you try it and find a website or application where it could work better, I’d love to hear about it. Click. WhatsApp. Done.
