How to Scan Documents on iPhone — 4 Methods 2026

The iPhone's built-in scanner — hidden inside the Notes app — is genuinely excellent. It auto-detects document edges, applies perspective correction, and saves multi-page PDFs with text-searchable OCR. You don't need to download anything. This guide covers all four methods, including how to share scanned documents securely.

Method 1 — Notes App (Best Quality, No Install Needed)

The Notes app scanner is the best option built into iOS. It produces higher quality output than most third-party apps because it uses the same computational photography pipeline as the Camera app.

1. Open the Notes app (pre-installed on all iPhones)
2. Tap the compose button (pencil icon, top right) to start a new note
3. Tap the camera icon above the keyboard (not the attachment icon — the camera icon in the toolbar)
4. Tap Scan Documents
5. Hold the iPhone above the document — a yellow border appears when edges are detected
6. The scanner captures automatically in Auto mode, or tap the shutter manually in Manual mode
7. Scan additional pages immediately (they add to the same document)
8. Tap Save when done — the scan appears in the note

To save as PDF: Tap the scan in the note → tap the share icon (square with arrow) → tap Save to Files. The file is saved as a PDF in the location you choose.

Best for: All users. No account required, highest quality output, multi-page PDFs, iCloud sync optional.

Method 2 — Files App (Scan Directly to Files)

iOS 13+ added document scanning directly into the Files app:

1. Open the Files app
2. Navigate to the folder where you want to save the scan (e.g., On My iPhone or iCloud Drive)
3. Tap the three-dot menu (—) in the top right → tap Scan Documents
4. Scan the document; when finished, tap Save
5. The PDF appears directly in the current Files location — no share step required

Best for: Users who want scans going straight to a specific folder without the Notes intermediate step.

Method 3 — Continuity Camera (Mac + iPhone Together)

If you're working on a Mac and need to scan a physical document directly into a Mac application, Continuity Camera handles it without any cables.

1. On your Mac, place your cursor where you want the scan to appear (in Pages, Word, Finder, etc.)
2. Right-click (or Control-click) → Import from iPhone or iPad → Scan Documents
3. Your iPhone's camera activates automatically
4. Scan the document on your iPhone — it transfers to your Mac over Wi-Fi instantly

Requires: iPhone and Mac signed into the same Apple ID, with Bluetooth and Wi-Fi enabled on both. No cables, no apps. Supported in Finder, Preview, Pages, Numbers, Keynote, Mail, Messages, and most standard Mac document apps.

Best for: Mac users who need scanned documents inserted directly into Mac workflows.

Method 4 — Third-Party Apps (Microsoft Lens / Adobe Scan)

Two third-party apps worth knowing:

Microsoft Lens:

• Whiteboard mode removes shadows and glare from whiteboard photos — Notes app doesn't do this
• Saves to OneDrive, local Photos, or as PDF directly
• Best when you need whiteboard capture or direct OneDrive integration

Adobe Scan:

• Auto-captures as soon as it detects a stable document — fastest shutter response
• Best OCR (optical character recognition) quality for text-heavy documents
• Integrates with Adobe Acrobat for editing signed scans
• Requires free Adobe account

For most iPhone users, the built-in Notes scanner is better than both. The third-party apps add value only for specific edge cases (whiteboards, high-volume OCR workflows).

How to Share a Scanned Document Securely

Standard sharing options (email, AirDrop, iCloud Drive) are convenient but expose your document to third-party services that can read it. For sensitive scans — medical results, legal contracts, financial documents, tax returns — a zero-knowledge workflow keeps the content private:

1. Scan with Notes and save to On My iPhone (not iCloud Drive)
2. Open FileShot.io in Safari on your iPhone
3. Tap Drop files here and select the scanned PDF from Files
4. FileShot encrypts the file in your browser with AES-256-GCM before it leaves the device
5. The server receives only ciphertext — it never sees the document content
6. Copy the generated link and share directly with the recipient
7. Set an expiry if needed (e.g., link expires after 1 download or 7 days)

The decryption key is embedded in the URL fragment (the part after #) and is never sent to any server. Only someone with the full link can decrypt and view the document.

iPhone Scanner Comparison

Tips for the Best iPhone Scan Quality

• Use Auto mode — let the iPhone decide when to capture. Manually pressing the shutter while holding the phone introduces blur.
• Good lighting is critical — iPhone cameras handle low light well for photos, but document scanners perform best with even lighting from above. Avoid one-sided shadows on the document.
• Dark background — scan white paper against a dark desk or table surface for best edge detection.
• Flatten the document — for pages from a book or folder, flatten the spine before scanning. Curved pages introduce perspective error that degrades OCR quality.
• For receipts — use Scan Documents (not camera photo). The Notes scanner enhances contrast specifically for printed text and makes faded receipt ink much more readable.
