If you've ever used insta zoom
Instagram, you've probably noticed that you can't enlarge the profile picture of people you don't follow. This can be very annoying, especially when trying to distinguish between two people with similar usernames. Fortunately, there are a few ways around this limitation.
First of all, you can always use a third-party Instagram magnifier app. These apps allow you to view profile pictures in the browser or download them to your computer. Once you have downloaded your profile picture, you can use it as your profile picture on your computer, tablet or phone. You can also download them to your mobile device and set them as wallpaper.
