How to send GIFs in WhatsApp

Easiest of all:

Copy and Paste from the internet

You can’t save GIFs in iOS and then send them from WhatsApp, but you can bypass this simply by copying and pasting.

If you find a GIF you like on the internet you can copy it by holding down and selecting “Copy”. Then just paste it into the WhatsApp text field and it will show up.
