Whatsapp has a way to backup as well, but I think you need to be using an iPhone. There's an option to store everything on iCloud, and from there you can access the iCloud backup folder via your computer. I don't remember the exact process, but it is possible - I had a few months of audio Whatsapp messages I wanted to backup/keep and was able to do it.
