Go to web.whatsapp.com on your desktop, scan the QR code on the screen with WhatsApp on your phone and you can instantly send or receive messages to any of your WhatsApp contacts from the computer.

WhatsApp supports desktop notifications in Google Chrome so you can read your messages even if the WhatsApp web app is open in some background tab. The other benefit is that you can send pictures from your desktop

The other limitation is that your mobile phone should be connected to the Internet for you to use WhatsApp on the web.

If you right-click on the profile picture of any WhatsApp contact, you’ll get a link that looks something like this;

https://web.whatsapp.com/pp?t=s&u=919966416345

Here the red string represents the phone number of your contact with the country code.
