Now you can use WhatsApp on PC in web browser?. Here’s how to use/access WhatsApp on Internet on Chrome web browser. WhatsApp has launched WhatsApp for Chrome, a web-based client. The WhatsApp web-based client currently only works with Chrome web browser.
The announcement on the WhatsApp blog says:
Today, for the first time, millions of you will have the ability to use WhatsApp on your web browser. Our web client is simply an extension of your phone: the web browser mirrors conversations and messages from your mobile device — this means all of your messages still live on your phone.
Please note that the WhatsApp web service is not available for iOS users. You must be a valid Android, Windows and Blackberry users. Also, you must be using the latest version of WhatsApp. You can download the latest version WhatsApp from the Play Store.
To log into the WhatsApp web service, go to the WhatsApp mobile app on the Android, Windows Phone, or Blackberry smartphone and navigate to the “WhatsApp Web” screen. Here you’ll need to scan a QR code (on the WhatsApp web-client page).
The WhatsApp blog says:
To connect your web browser to your WhatsApp client, simply open https://web.whatsapp.com in your Google Chrome browser. You will see a QR code — scan the code inside of WhatsApp, and you’re ready to go. You have now paired WhatsApp on your phone with the WhatsApp web client. Your phone needs to stay connected to the internet for our web client to work, and please make sure to install the latest version of WhatsApp on your phone. Unfortunately for now, we will not be able to provide web client to our iOS users due to Apple platform limitations.
