And with free* video calls, you can have face-to-face conversations for when voice or text just isn't enough.

Security by Default
Some of your most personal moments are shared on WhatsApp, which is why we built end-to-end encryption into the latest versions of our app. When end-to-end encrypted, your messages and calls are secured so only you and the person you're communicating with can read or listen to them, and nobody in between, not even WhatsApp.
PHOTOS AND VIDEOS
Share Moments that Matter
Send photos and videos on WhatsApp instantly. You can even capture the moments that matter to you most with a built-in camera. With WhatsApp, photos and videos send quickly even if you're on a slow connection.
Document Sharing Made Easy
Send PDFs, documents, spreadsheets, slideshows and more, without the hassle of email or file sharing apps. You can send documents up to 100 MB, so it's easy to get what you need over to who you want.
Say What's On Your Mind
Sometimes, your voice says it all. With just one tap you can record a Voice Message, perfect for a quick hello or a longer story.
