Zooming often improves image quality. Details that may be lost in the original image can be emphasized by zooming, resulting in a sharper and more appealing profile picture.
The zoom allows you to show your personality or your brand identity more clearly. For example, if you are a photographer, zooming can highlight a picture of you with your camera and show your passion for photography.
Choose an image that lends itself well to zooming. It should contain enough detail for the zoom to emphasize.
Make sure the composition of the image stays appealing even after zooming. Important elements should not appear cut off or distorted.
