How to Scan Documents on Mac Without a Scanner

And if you don't have an iPhone handy, your Mac's built-in camera plus a browser scanner covers you too.

The Continuity Camera route gives the best results because it uses the iPhone's rear camera and Apple's document detection. The built-in-camera route is the backup for iPhone-less moments. Either way, there's nothing extra to buy — here's how both work, step by step.

Your three options at a glance

• Continuity Camera (best). Scan from your iPhone directly into a Mac app — best image quality, auto page detection, multi-page PDFs. Needs an iPhone or iPad.
• Built-in camera + browser scanner. Use your Mac's FaceTime HD camera with a web-based scanner — no iPhone required, works on any Mac.
• A physical scanner via Image Capture. Only relevant if you actually own a scanner — Image Capture in your Applications folder drives real scanner hardware. It can't conjure a scanner out of thin air, so skip this if you don't have one.

Method 1: scan from iPhone into Preview with Continuity Camera

First, the one-time setup: you need a Mac running macOS Mojave or later and an iPhone or iPad running iOS 12 or later, both signed in to the same Apple ID, with Wi-Fi and Bluetooth turned on on both devices, and the devices near each other.

1. Open Preview on your Mac (from Applications or Spotlight).
2. Go to File → Import from iPhone or iPad → Scan Documents.
3. Your iPhone automatically switches to a scanning interface — you don't need to open anything on the phone yourself.
4. Position the document under the iPhone camera. It auto-captures when it detects the page; if it's too eager, tap Auto (top-right) to switch to manual shutter.
5. Use the Filters button to pick Color, Grayscale, Black & White, or Photo — black & white gives the cleanest text.
6. After each capture, tap Keep Scan (drag the corner circles first if the edges need adjusting) or Retake. Flip the page and keep going for multi-page documents — a review screen lets you swipe between pages.
7. Tap Save. The whole stack lands in Preview on your Mac as a PDF — scans are not stored on the iPhone itself.
8. Rename and save (File → Save) to a proper filename, and use Preview's markup tools to annotate or sign if needed.

Method 2: scan straight to a Finder folder

Don't need Preview at all? You can drop scans directly into a folder:

1. In Finder, Control-click the folder (or the Desktop) where you want the scan to land.
2. Choose Import from iPhone or iPad → Scan Documents.
3. Capture pages on your iPhone exactly as above — auto-capture, filters, Keep Scan / Retake per page.
4. Tap Save and a PDF called "Scanned Document" appears in the folder. Press Space for Quick Look, or rename it like any file.

The same command works inside Notes (File → Insert from iPhone or iPad), Pages, and Mail — the scan drops straight into your document or message without any intermediate file.

Method 3: no iPhone? Use the Mac's built-in camera

If there's no iPhone in the picture, your Mac's FaceTime HD camera plus a browser scanner does the job. Open Scanner.cam in Safari or Chrome, allow camera access when asked, and hold each page in front of the camera. Crop and straighten each capture, apply a document filter, add pages, and export one multi-page PDF. All processing runs on your Mac — the images never upload anywhere, which matters for IDs and contracts.

For a quick-and-dirty single photo, Photo Booth (in Applications) also captures from the built-in camera — but it won't straighten or clean the page, so the browser-scanner route gives far more scan-like results.

Tips for cleaner Mac scans

• Light the page, not the screen. Face a window or bright room; avoid your own shadow falling across the page when you hold the iPhone over it.
• Use a contrasting background. White paper on a dark surface helps auto-detection lock onto edges on both iPhone and webcam captures.
• Flatten the page. Curled or wrinkled paper defeats even Apple's detection — press it flat for a few seconds first.
• Name the file immediately. "Scanned Document.pdf" is a filing disaster waiting to happen — rename to something like "2026-10-19 Electricity Bill.pdf" while you remember what it is.
• Reduce PDF size in Preview. After importing, use File → Export and pick a Quartz Filter (like "Reduce File Size") if you need a lighter file for email.

FAQ

How do I scan documents on a Mac without a scanner?
The easiest way is Continuity Camera: on your Mac open Preview and choose File → Import from iPhone or iPad → Scan Documents, then capture pages on your iPhone — they land on the Mac as a PDF. No iPhone? Use your Mac's built-in camera with a browser scanner like Scanner.cam.

What do I need for Continuity Camera scanning?
A Mac running macOS Mojave or later and an iPhone or iPad running iOS 12 or later, both signed in to the same Apple ID with Wi-Fi and Bluetooth turned on, and both devices near each other.

Where do iPhone scans go on the Mac?
Wherever you started the import: into the open Preview window, into the Finder folder you Control-clicked, or directly into a Notes, Pages, or Mail document. Scans are not saved on the iPhone itself.

Can I scan multi-page documents with Continuity Camera?
Yes. Keep capturing pages — the iPhone shows a review screen where you can crop, retake, or delete each page — then tap Save and the whole stack arrives on your Mac as a single PDF.

Can Image Capture scan without a scanner?
No — Image Capture only works with an actual scanner or camera device connected to your Mac. If you don't own a scanner, use Continuity Camera from an iPhone or a browser-based scanner with your Mac's built-in camera instead.
