Use the Built-In Notes App to Scan Documents

Your iPhone has a document scanner built into the Notes app — you do not need to read anything. Open Notes, create a new note or open an existing one, tap the camera icon at the bottom, then tap "Scan Documents". Point your phone's camera at the document, and the iPhone will automatically detect the edges and snap a photo when it has a clear view. You can scan multiple pages into a single document by holding the phone steady after each scan.

After you finish scanning, the app shows you all the pages you captured. You can rotate, crop, or delete individual pages before saving. Tap "Save" and choose where to store the document — it saves as a PDF by default. From there you can email it, share it to cloud storage like iCloud Drive or Google Drive, or send it to another app on your phone.

This method works best for documents that are mostly text or straightforward images. The scanner adjusts brightness and contrast automatically, which usually produces clean, readable PDFs without extra steps.

Key Takeaways

  • The Notes app on every iPhone includes a document scanner — open Notes, tap the camera icon, then tap "Scan Documents".
  • The iPhone automatically detects document edges and saves scans as PDFs that you can rotate, crop, or delete before saving.
  • You can scan multiple pages into one document by scanning each page in sequence without closing the scanner.
  • After saving, you can email the PDF, upload it to cloud storage, or move it to another app directly from Notes.

Scanning Multiple Pages Into One PDF

When you are scanning a multi-page document, keep the scanner open after the first page captures. The app shows a thumbnail of the page you just scanned and a button to add another page. Tap that button, position the next page in front of your camera, and let the iPhone detect and snap it. Repeat for each page you need to scan.

The order matters — pages appear in the PDF in the order you scanned them. If you scan them out of order by mistake, you can rearrange them before saving. Tap and hold a page thumbnail, then drag it to a new position in the list. You can also delete a page by swiping left on its thumbnail and tapping the trash icon.

Adjusting Brightness, Contrast, and Color

After you scan all pages but before you save, tap the three-dot menu icon at the top right of the scanner screen. You will see options for "Color", "Grayscale", or "Black and White". Choose the option that makes your document easiest to read. Black and White produces the smallest file size and works well for text documents. Grayscale preserves some detail if your document has photos or shading. Color keeps everything as it appears but creates a larger file.

You can also adjust the filter by tapping "Filter" in that same menu. The app offers several automatic adjustments — try each one and pick the version that looks clearest on your screen before you save.

Saving and Sharing Your Scanned Document

Once you are happy with how your pages look, tap "Save" at the bottom right. The app asks you to name the document and choose a folder within Notes. Type a name that will help you find it later — something like "Lease Agreement 2024" or "Medical Records March" works better than "Scan 1". Then tap "Save".

The PDF now lives in your Notes app. To share it, open the note containing your scan, tap the three-dot menu at the top right, and tap "Share". You can email it, send it through Messages, save it to Files, upload it to iCloud Drive, or open it in another app. If you want to move it to your computer, email it to yourself or upload it to a cloud service like Google Drive, OneDrive, or Dropbox, then read it on your computer later.

When to Use the Files App Instead

If you want your scanned documents organized in a dedicated folder on your phone rather than scattered through Notes, you can use the Files app with a third-party scanner. Apps like Adobe Scan, Microsoft Lens, and Scanbot are free and save PDFs directly to your Files app or cloud storage. These apps offer more control over naming and organization, and they work the same way as the Notes scanner — point, snap, adjust, save.

The Notes scanner is simpler if you only scan occasionally. The third-party apps are worth downloading if you scan documents regularly and want them all in one organized place. Both produce good-quality PDFs, so the choice comes down to where you want your files to live.

Fixing Common Scanning Problems

If the iPhone does not detect your document, make sure you have enough light. The scanner needs to see the edges clearly, so scan near a window or under a lamp rather than in dim light. Hold the phone about 12 inches away from the document and keep it as level as possible — tilting the phone too much confuses the edge detection.

If your scanned document looks blurry or dark, try scanning again with better lighting. You can also try adjusting the filter or color mode before saving — sometimes switching to Black and White or Grayscale makes a blurry scan readable. If a page is still unusable, delete it and scan that page again.

If the PDF file is too large to email, compress it before sending. Open the note, tap the three-dot menu, tap "Share", then choose "Mail". Before you send, the Mail app usually offers a "Reduce File Size" option. Tap that, and the app will compress the PDF so it fits within email size limits.

Frequently Asked Questions

Can I scan a document directly into an email on my iPhone?

Yes. Open Mail, start composing a new message, tap and hold in the body of the email, then tap "Add Attachment". Tap "Scan Documents", and the scanner opens. Scan your pages, adjust them if needed, tap "Save", and the PDF attaches to your email automatically.

What if I need to scan a document that is larger than a standard page?

Scan it in sections. Scan the top half as one page, then scan the bottom half as another page in the same document. When you open the PDF on your computer, you will see two pages, but you can read the full document. If you need it as one continuous image, you can use a PDF editor on your computer to combine or crop the pages later.

Does the iPhone scanner work with handwritten documents?

Yes. The scanner treats handwriting the same as printed text — it detects the page edges and saves what it sees. Handwriting may be harder to read in the PDF if the original is small or faint, so make sure you have good lighting when you scan.

Can I edit a scanned document after I save it?

The Notes app does not let you edit the PDF itself, but you can delete pages and rescan them. Open the note, tap "Edit", then tap the three-dot menu on the PDF. You can delete the entire scan and start over, or you can share the PDF to a PDF editor app that lets you add text, highlight, or make other changes.

Where do my scanned documents go if I back up my iPhone?

Scans saved in Notes go to iCloud if you have iCloud backup turned on. They sync across all your Apple devices. If you use a third-party scanner app, check that app's settings to see whether it backs up to iCloud, Google Drive, or another cloud service.
