WhatsApp is occupying 2.64 GB of my Nokia Lumia 730 phone

The phone notifies me of full memory. I moved all photos and videos to my laptop and cleared the messages history but still WhatsApp is occupying 2.64 GB of the phone memory.
What can I do to free the phone's memory?

from whatsapp, do a backup and then uninstall it. Once it has uninstalled install it again, it will clear the memory and the size should be about 100MB
