Scan Code
Scan QR Code
Using WhatsApp Web, which is a browser-based application that runs on Google Chrome etc., or via WhatsApp Desktop, which is a desktop application that you can download on your computer to reduce the need of opening your browser every time.
On your device, open the browser of your choice and visit Web.whatsapp.
Scan the QR code that appears on the screen. If you have an Android smartphone, open WhatsApp > tap the vertical three-dots icon and select WhatsApp Web.
Similarly, if you have an iPhone, open WhatsApp > tap Settings > followed by tapping WhatsApp Web.
Now, scan the QR code that's there on your computer screen. That's it, WhatsApp Web will now be active on your computer system.
You can simply start chatting with your contacts by opening their chat threads. Besides, you can also start a new chat by clicking on the new chat icon.
Just for the record, WhatsApp Web works on both Mac and Windows PC.
Note: For WhatsApp Web, your phone on which your WhatsApp account is active needs to be turned on along with having an active internet connection.
On your device, visit Web.whatsapp download website.
Under Download WhatsApp for Mac or Windows PC, click the green Download button. Note, that the website automatically detects whether you're using a Mac or a Windows PC, so you don't really have to look for a particular version for your system.
Once your file is downloaded, install it on your system and open it.
You'll now see the familiar QR code, just like the one you see when you open WhatsApp Web on a browser.
Scan the QR code from your phone by opening WhatsApp. If you have an Android smartphone, open WhatsApp > tap the vertical three-dots icon and select WhatsApp Web. Similarly, if you have an iPhone, open WhatsApp > tap Settings > followed by tapping WhatsApp Web.
Before scanning the code, make sure you check the Keep me signed in option right below the QR code. This is to be done so that you don't have to scan the code each and every time you open the app.
That's it. You now have WhatsApp running as an app on your computer.
