Instagram shows you a preview of your profile picture as it will be visible to other users. Make sure it looks good and properly represents your personality or brand.
There are various online tools and mobile apps that you can use to enlarge your profile picture. Upload your profile picture and select the desired size. These tools adjust the image without compromising the quality.
After you've enlarged your profile picture, you'll want to make sure it stays within the designated square. Instagram profile pictures are typically square, so it's important to crop your image accordingly so it doesn't become distorted.
