If you don't want your entire face to be hidden in your WhatsApp profile picture, you can choose to crop your photo. To do this, open the WhatsApp app and go to your profile. Then, tap on the pencil icon next to your name and select Edit Profile. From here, you can tap on the camera icon next to your current profile picture and select Crop Photo. This will allow you to crop out any part of the photo that you don't want visible.
