To use WhatsApp on your computer, you can either use the WhatsApp Web or the WhatsApp Desktop application.
To use WhatsApp Web, you need to open WhatsApp on your phone, tap on the CHATS tab > More options (three dots on right-top) > WhatsApp Web, and then scan the QR code that appears on the web.whatsapp "web.whatsapp" Link: [sites.google.com page on your computer. This will link your phone and computer, allowing you to view conversations on any device regardless of where they are initiated.
Alternatively, you can download and install the WhatsApp Desktop application from the official WhatsApp website "WhatsApp Desktop App" Link: [whatsapp.com. Once installed, open the application, and a screen with a QR code will appear. Tap Menu or Settings and select Linked Devices, then tap on Link A Device, and scan the QR code on your Desktop Screen.
Both methods allow you to use WhatsApp on your computer, but the WhatsApp Desktop application provides a more native experience and can show notifications on your computer, even if you're doing something else.
