Official WhatsApp for Windows desktop application alows you to stay in touch anytime and anywhere – whether on your phone or computer at home or work. The app itself is quite similar to WhatsApp Web that was meant to be an extension of your phone: the app mirrors conversations and messages from your mobile device.
The WhatsApp for PC offline installer is available for Windows 8 and later and is synced with your mobile device. Because the app runs natively on your desktop, you’ll have support for native desktop notifications and better keyboard shortcuts.
Just like WhatsApp Web, the New Desktop App lets you message with friends and family while your phone stays in your pocket. WhatsApp must be installed on your cell phone so you can use WhatsApp on your PC. WhatsApp supports only 64-bits versions of Windows.
Note: WhatsApp must be previously installed on the mobile phone.
