Start with the profile
Paste an instagram.com/username/ link or @username into the Profile tool. The result shows the image Instagram makes publicly visible, including the public avatar of a private account when available.
What a profile result includes
The source controls the available picture dimensions. For public profiles, some publicly exposed recent items may also appear. Private profiles return only their public picture. A profile lookup is not a full account archive and does not provide access to private posts, private Stories or restricted content.
