Photo privacy guide
What Information Can a Photo Reveal?
A photo can reveal information in two layers: hidden metadata attached to the file and visible details inside the image. Checking only one layer can leave the other untouched.

Hidden information
The file may contain capture time, coordinates, device details, author text, notes, captions, or editing metadata. Which fields exist depends on the source and format.
Metadata is useful for sorting and editing, but the recipient may not need it. Inspect the exact copy you plan to send.
Visible information
Names, addresses, phone numbers, email, account details, IDs, faces, QR codes, barcodes, screens, reflections, and background documents can all identify a person or place.
Cropping can work when the private detail is outside the useful scene. Redaction is better when you need to keep the surrounding context.
Context changes the risk
The same detail can be harmless in one destination and sensitive in another. A face shared with family is different from a bystander posted publicly; a parcel label sent to support is different from one posted on social media.
Review both the file and the audience. No automated detector can understand every context or guarantee that nothing was missed.
Use a two-layer check
Scan hidden and visible information, fix only what is not needed, generate a separate copy, and verify the output. Keep the original untouched so a privacy edit never destroys the source.
