Now select a picture which you want to use as your WhatsApp Profile Picture.
Now you have multiple choices to choose background color or patterns, The first one will add white background. If you want to set some custom color then you can select the second button. I usually select blur (third one) as it looks good.
If you scroll on the right side then you can have varieties of different patterns and designs. You can experiment with these and find the one which suits you.
Tap on the share icon on the top right corner and select Save. The picture will be automatically saved to your gallery.
Now open WhatsApp, Instagram or Facebook and set your profile picture without cropping.
