What metadata can be stored inside photos and PDF documents?
When you look at a photo or PDF, you normally see only the visible content: the image, text, table, or document page. But a digital file can also contain additional technical information known as metadata.
Photos often contain EXIF metadata. Depending on how the image was created and what settings were enabled, this can include the date and time, device model, camera parameters, and sometimes location information.
For ordinary photography, those details can be useful. The Photos app may use them to sort images by date, organize trips, or help you find pictures later.
For documents, however, some of that information may be unnecessary.
If someone photographs a document at home and later sends the original image, additional information associated with the file may travel with it even though it is not visible on the page itself.
PDF files can also contain metadata such as title, author, the software used to create the file, creation dates, modification dates, and other document properties.
Metadata is not inherently dangerous. The issue is awareness: a user may believe they are sharing only what is visible on the page while the file contains additional information.
For sensitive material, it is useful to follow a simple rule: treat the file itself as potentially richer than what you can see on screen.
Before sharing an important document, consider whether every piece of information associated with that file is actually necessary for the recipient.
