To set expectations correctly, here is what anyone can see without hacking:

| Privacy Setting | What’s Visible | |---------------------|--------------------| | Public profile | Name, profile picture, cover photo, public posts | | Private profile | Name, profile picture (small thumbnail), cover photo, mutual friends | | Limited info | Age range, gender, networks (depending on settings) |

Facebook deliberately shows a low-resolution thumbnail of the profile picture to non-friends. No tool can magically reveal the high-resolution version unless the user changes their privacy setting to "Public."

Accessing private Facebook data without permission violates:

If you attempt to view a private profile photo, you will only see the small thumbnail that Facebook shows publicly (the default silhouette or the user's chosen small avatar). The full-resolution image remains inaccessible.
