How to Scan With iPhone: Documents, QR Codes, and PDFs

If you’ve ever needed to scan a document or QR code on your iPhone, you might have found yourself hunting through apps—Apple doesn’t offer a single “Scan” button, instead spreading scanning across Notes, Files, and the Camera app. This guide shows you where to find each tool and how to use them on any iPhone running iOS 11 or later.

iPhones with built-in document scanner: All models running iOS 11 or later (iPhone 5s and newer) ·
QR code scanning via Control Center: Available since iOS 11 (2017) ·
Notes app document scans per minute: Over 1,000 scans via continuous mode ·
Native scanner apps on iPhone: 3: Notes, Files, and Camera

Six key facts about iPhone scanning, all from Apple’s official documentation:

Where is the scan tool on iPhone?

Apple hides scanning in three different apps. Here’s exactly where each one lives.

Scanning in the Notes app

Open a note, tap the camera icon above the keyboard, and select Scan Documents. The camera viewfinder opens, and the iPhone automatically detects page boundaries. You can tap the shutter button for manual capture or let auto-capture take over. After each page, tap Keep Scan to continue, then Save when done. All pages are attached as a single PDF within the note. Apple Support (official iPhone guide)

Scanning in the Files app

Open the Files app, navigate to a folder, tap the More button (three dots) in the top right, then choose Scan Documents. The same scanner interface appears. After scanning, the PDF is saved directly into the chosen folder, ready to rename, move, or export. Apple Support (document scanning guide)

Scanning with the Camera app

The Camera app does not scan documents — it only reads QR codes. To scan a QR code, open the Camera app in Photo mode, point it at a QR code, and wait for a yellow banner with a link to appear at the top of the screen. Tap the banner to open the link. This works on all iPhones with iOS 11 or later. Apple Support (QR code guide)

How do I scan a QR code on my iPhone?

QR scanning is built into the Camera app, but there are three ways to do it depending on where the code appears.

Scanning QR codes with the Camera app

Make sure QR scanning is enabled: go to Settings > Camera and toggle on Scan QR Codes. Then point the rear camera at a QR code. A notification appears at the bottom of the screen with the code’s link. Tap it to open. Apple Support (QR code guide) On supported models, you can also use the Camera Control button.

Scanning QR codes from a photo or screen

If a QR code appears in a photo, open the photo and long-press on the code. If Live Text is active (iOS 15+), a Scan QR Code option appears. If not, take a screenshot of the screen, then open it in Photos and long-press. Alternatively, use the Control Center QR scanner. The QR Code Generator (third-party guide)

Using Control Center QR scanner

Add the Scan Code control to Control Center: go to Settings > Control Center and tap the plus sign next to Scan Code. Then open Control Center and tap the QR code icon to launch the scanner. Apple Support (Control Center guide)

How do I scan a document from my iPhone as a PDF?

Both Notes and Files save scanned documents as PDFs automatically — no extra steps needed.

Scanning to PDF in Notes

Open a note, tap Camera > Scan Documents, capture pages, and tap Save. The scanned document appears as a PDF attachment inside the note. Tap the PDF to preview, share, or export it. Apple Support (official iPhone guide)

Scanning to PDF in Files

Open Files, navigate to a folder, tap More > Scan Documents, scan, and save. The PDF is stored directly in that folder as a file ready to email, upload, or send. Apple Support (document scanning guide)

Saving scanned document as PDF

Both apps default to PDF format. If you scan with a third-party app like Adobe Scan, you can also export as JPEG or TIFF, but native tools always produce PDF. University of Missouri–St. Louis (university help page)

The catch: you cannot choose a different format from Apple’s built-in scanners — it’s PDF only. For color photos or receipts, that’s usually fine; for OCR-heavy workflows, third-party apps offer more flexibility. If you need to convert your PDF to images, see our guide on Best Free PDF to JPG Converters.

“Lay the document flat and do not hold it while scanning. Auto mode will scan automatically and manual capture can be triggered with the shutter or volume buttons.”

How to scan documents on iPhone into PDF files using Adobe?

Adobe Scan is a free third-party alternative that adds OCR and cloud features.

Setting up Adobe Scan

Download Adobe Scan from the App Store (free). Open the app and grant camera permission. The app automatically detects document edges and can enhance contrast, remove shadows, and straighten pages.

Scanning with Adobe Acrobat

Point the camera at a document. Adobe Scan captures the page, applies automatic image correction, and lets you review the result before saving. You can adjust corners manually if needed.

Saving and sharing PDFs

Tap Save PDF to store the document in Adobe cloud, or export it to Files, email, or other apps. The OCR feature makes the text searchable — something Apple’s native scanner does not offer.

How to scan with iPhone Notes?

The Notes scanner is the most accessible built-in tool. Here’s the full workflow.

1. Create a new note or open an existing one.
2. Tap the camera icon above the keyboard and choose Scan Documents. The viewfinder opens in auto-scan mode.
3. Scan one page, then tap Keep Scan to add another. You can scan dozens of pages in one session — there’s no limit.
4. After the last page, tap Save to attach all pages to the note as a single multi-page PDF.
5. Once saved, you can tap the PDF to mark up, crop pages, or share via email, Messages, or AirDrop. From the note, tap the share button to send the entire note with attachments.

The implication: Notes scanning is ideal for quick, in-app document capture without leaving the note.

How to scan with iPhone camera for QR codes?

The Camera app is the fastest way to scan a physical QR code — no app switching needed.

Enabling QR scanning in Camera settings

Go to Settings > Camera and turn on Scan QR Codes. This is enabled by default on newer iPhones, but worth checking if scanning doesn’t work immediately.

Pointing the camera at a QR code

Open Camera in Photo mode and hold your iPhone so the QR code fills the frame. A yellow banner appears at the top of the screen with the link. Tap it to open. The code doesn’t need to be perfectly centered — the iPhone automatically detects it.

Troubleshooting QR code scanning

If no banner appears, check that the code is well-lit and not damaged. If the code is on a reflective screen, try adjusting the angle. You can also use the Control Center scanner as a backup.

What this means: The Camera app is the fastest way to scan physical QR codes, but requires good lighting and a clean code.

How to scan with iPhone 15, 16, and 17 models?

All modern iPhones use the same scanning workflows. The hardware hasn’t changed the software.

Using the Action button for scanning

On iPhone 15 Pro, 16, and 17 models, you can assign the Action button to open the scanner app (Notes or a third-party scanner). Go to Settings > Action Button and choose a shortcut that launches scanning.

Camera improvements on newer models

Newer iPhones have better cameras, which can improve edge detection and low-light scanning, but the scanning feature itself is identical to iOS 11’s implementation. No new scan-specific features were introduced. Apple Support (QR code guide)

Same steps apply across models

Whether you own an iPhone 15, 16, or 17, the steps in Notes, Files, and Camera are exactly the same. The Action button is the only model-specific addition for scanning.

“Open a note, tap the Attachments button, then tap Scan Documents. The iPhone automatically captures pages when it detects the boundaries of a document.”

“The QR-code notification appears at the bottom of the screen on iPhone. Tap the link to open it.”

Frequently asked questions

For iPhone users who regularly scan documents, the native Notes and Files tools are free, fast, and already on your phone. The trade-off is format lock-in (PDF only) and no OCR. If you need searchable text or JPEG output, Adobe Scan or Microsoft Lens fill that gap. The choice is simple: stick with Apple for convenience, or add a third-party app for flexibility.
