GIF support in WhatsApp Beta for Windows 10 Mobile was a much-awaited feature. This feature had already arrived on WhatsApp Beta for Android and iOS. Last we reported about it being available in WhatsApp Web when you connect your Windows 10 Mobile device.
Now the feature has finally arrived on Windows 10 Mobile WhatsApp Beta. As you can see in the screenshots above, once you bring the Keyboard, you will see GIF option on the bottom. Tapping on GIF allows one to search GIFs from GIPHY.
We can soon expect GIF support to make its way to the stable WhatsApp app in Windows 10 store.
