With over 600 million users globally, WhatsApp till now was available only on smartphones across operating systems Android, iOS, Windows and BlackBerry.
    
"Today, for the first time, millions of you will have the ability to use WhatsApp on your web browser," WhatsApp said in its blog.
    
The web client is an extension of the user's phone with the web browser mirroring conversations and messages from the user's mobile device, it added.
    
"This means all of your messages still live on your phone," it said.
    
To connect the web browser to WhatsApp client, users need to open 'web.whatsapp.com' in Google Chrome browser and scan the QR code inside of WhatsApp.
    
"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," it said.
    
Currently, the service is available only for Android devices as Apple platform has certain limitations.
    
WhatsApp's user base in India has grown to 70 million active-users, accounting for over a 10th of its global users.
    
Bought over by social networking giant Facebook last year in a blockbuster USD 19-billion deal, WhatsApp is very popular in markets like India and Brazil.
