Sometimes I just like to run WhatsApp from my PC to get a bigger screen and, more practically, when I’m on the PC and don’t want to keep picking up my phone to chat.
To get started with WhatsApp Web
1. Visit web.whatsapp.com on your computer.
2. Open WhatsApp on your phone.
3. On Android: in the Chats screen > Menu > WhatsApp Web. On Nokia S60 and Windows Phone: go to Menu > WhatsApp Web. On iPhone: go to Settings > WhatsApp Web. …
4. Scan the QR Code on your computer screen from your phone.
