What is WhatsApp Messenger?

WhatsApp Messenger is a widely-used instant messaging application owned by Meta Platforms Inc., designed to facilitate free and secure communication across the globe. Launched in 2009, WhatsApp allows users to send text messages, voice notes, images, videos, documents, and make voice and video calls using an internet connection rather than traditional cellular networks. The app’s end-to-end encryption ensures privacy, making conversations accessible only to the communicating parties.
