Although this feature has been on WhatsApp since early this year, not too many people know about it. So let my be the one to tell you that you can actually send GIFs (Moving Images) on WhatsApp the same way you would send a normal smiley. The feature is a bit hidden though, probably why it’s not as common.

How to send GIFs on Android WhatsApp

First off, select the smiley face, the same way you would if you want to send a smiley
