You cannot directly view EXIF data on a Facebook photo. Facebook intentionally removes this data from all uploaded photos in an effort to protect privacy. You can still get some metadata related to the photo by looking at the post’s metadata. Or, you can ask the uploader about the photo directly.
Simply put, you cannot view EXIF data on a WhatsApp photo. The WhatsApp service intentionally scrubs away all EXIF data before transmitting a photograph. This is done in keeping with the privacy policy. If you want to see EXIF data, then you will need to reach out to the picture’s original owner.
Instagram destroys EXIF data when pictures are uploaded to the platform. That means that you cannot view EXIF data on an Instagram photo because the data doesn’t exist. You can view EXIF data on your originals that you upload to Instagram, but you have to get the data from your device and not the Instagram app.
