Photo metadata (EXIF): what your document scans reveal — and don’t

Every phone photo carries EXIF metadata: timestamp, device model, camera settings — and, if enabled, GPS coordinates. Share a raw photo of a document and you may share where and when it was taken. Scans deserve a cleaner story.

What EXIF typically contains

• Date and time of capture
• Device make/model, lens and exposure settings
• Orientation (how the camera was held)
• GPS location, when camera location tags are on

Harmless for holiday snaps; less great appended to your rental application photographed at home.

What ToPDF does with it

The pipeline reads orientation from EXIF (so photos come in the right way up) and then re-renders the page as a new image — cropped, corrected, enhanced. The PDF embeds that freshly rendered image: your camera's metadata block, including any GPS tags, is not copied into it. What you share is the document's content, not your photo's diary.

Habits that close the loop

• Consider turning camera GPS tagging off for document photos (or generally): Settings → Privacy → Location → Camera on iOS; Camera app settings on Android.
• When sharing raw photos instead of scans, remember messengers vary — some strip EXIF, some don't.
• Delete the original camera-roll photo once the scan is saved, if the photo has no keeper value.

Frequently asked questions

Does the PDF contain any metadata at all?

PDFs have their own minimal properties (like creation info), but ToPDF’s output does not carry over your camera’s EXIF block or location data from the source photo.

Can recipients see when I scanned it?

File systems and email show file dates as usual. That’s normal document behaviour — the sensitive part (GPS, device fingerprints from the photo) is what the re-render leaves behind.
