How to scan documents privately on iPhone

Your iPhone is a capable scanner, which is handy for a passport page, a lease or a lab result. The problem is that the obvious way to do it, taking a photo, puts a copy of that document into your photo library, into iCloud, and possibly into Memories or a shared album. A few small changes in how you scan keep sensitive papers where you want them.

Why not just take a photo?

A photo of a document is treated like any other photo. It appears in your camera roll, it syncs through iCloud Photos, it may be picked up by search (iOS recognises text in photos), and any app with full photo access can read it. If you then hide it, it still syncs, as explained in are hidden photos saved to iCloud?

A document scanner is a tool that detects the edges of a page, flattens the perspective and saves the result as a document, usually a PDF. iOS includes one in two places that don’t touch your photo library at all: the Files app and Notes.

Option 1: Scan with the Files app

Files is the better choice when you want a standalone PDF you can move elsewhere.

1. Open Files and go to the Browse tab.
2. Tap the More button (three dots in a circle) at the top of the screen.
3. Choose Scan Documents.
4. Hold the iPhone over the page. It captures automatically when the page is detected, or you can tap the shutter. Adjust the corners if needed.
5. Scan further pages if the document has several, then tap Save.
6. Choose where to save. Pick a folder under On My iPhone, not iCloud Drive.

Where the scan is stored

• On My iPhone keeps the file on the device. It is protected by iOS Data Protection while the phone is locked, and it may be included in device backups.
• iCloud Drive uploads the file to Apple’s servers and syncs it to your other devices. It’s end-to-end encrypted only if you have Advanced Data Protection turned on.

If the save screen opens inside iCloud Drive, tap back until you see the list of locations, then pick On My iPhone. You can create a dedicated folder there for scans.

Option 2: Scan into Notes

Notes is convenient when you want a scan together with some text, for example a document and a short note about it.

1. Open Notes and create a new note.
2. Tap the attachments button (a camera icon on older versions; a paperclip on newer ones) and choose Scan Documents.
3. Scan the pages and tap Save. The scan is embedded in the note.

Where the scan is stored

The scan lives inside the note, not in Photos. Where the note lives depends on its account:

• iCloud notes sync to all your devices and to Apple’s servers.
• On My iPhone notes stay on the device. If you don’t see this account, look for an option to enable an On My iPhone account in the Notes settings (Settings › Apps › Notes on iOS 18 and later; Settings › Notes on older versions).

Locking the note

Notes lets you lock a note with your device passcode or a separate Notes password; locked notes are encrypted. Open the note, tap the More button and choose Lock. A separate password adds a real extra layer, because your device passcode alone won’t open it. Our comparison of Velcrypt and locked notes goes into the differences.

A note on third-party scanner apps

Many scanner apps on the App Store offer text recognition, cloud storage or automatic sync. Some of these features process your pages on remote servers. For a shopping receipt that may not matter; for a passport or medical report it might. Before using one, check its App Store privacy label and whether it requires an account, and try it in Airplane Mode. Our no-account vault guide explains those checks.

Moving scans into an encrypted vault

Locking a note or keeping a PDF in On My iPhone is a good start, but anyone who can unlock your phone can still open Files. For identity documents, medical records and anything you’d hate to see leaked, moving the scan into an encrypted vault adds a separate secret.

Velcrypt can import documents from the Files app into an encrypted vault (private documents). Files are encrypted with AES-256-GCM on the device using keys derived from your unlock pattern, and nothing is uploaded (offline, no account). Velcrypt doesn’t have a built-in scanner or camera, so you scan with Files or Notes first and then import the PDF.

Keep in mind that in the first version, vault content is not included in iCloud or computer backups. If an original document is irreplaceable, keep the paper version or another copy somewhere you control. Our use case on medical and ID documents covers that balance.

Cleaning up the leftovers

Importing a scan into any vault copies it. The original stays where you saved it until you delete it, and deleting it isn’t the end either.

1. Files: delete the PDF, then go to Browse › Recently Deleted and delete it there too.
2. Notes: delete the note, then open the Recently Deleted folder in Notes and delete it permanently.
3. Photos: if you ever photographed the document, delete it and empty Recently Deleted in Utilities. Our guide to deleting originals has the details.
4. Shared copies: if you emailed the scan or sent it in a chat, those copies remain in the sent folder and on the recipient’s device.

Items in Recently Deleted are kept for up to 30 days, so this step matters.

Extra precautions for sensitive documents

• Crop what you don’t need. If a form only needs one page, don’t scan the whole booklet.
• Watch the background. A scan can include your desk, a letter with your address, or reflections.
• Mind the metadata on photos. Scans from Files and Notes are PDFs, but if you do use a photo, it may carry location data; see removing photo metadata.
• Share deliberately. When an organisation asks for a copy, send only that document, and consider adding a watermark noting who it is for using the Markup tool.
