Make sure your profile picture is insta zoom high quality. Instagram displays profile pictures at a small size, so it's important that the image is sharp and clear to be effective.
Your profile picture will be displayed in a square format, so you should choose an image that fits well in this format. If you have a rectangular image, you can crop it in the Instagram app.
Your profile picture should reflect your personality or branding. It can be a personal photo of you or your logo, depending on how you want to present yourself on Instagram.
Instagram offers a variety of filters that can give your profile picture a unique look. However, adjust the filters so that they fit your branding and don't seem too over the top.
