The iPhone's built-in scanner is faster than you might think

Your iPhone has a document scanner built into the Notes app and the Files app — you do not need to read anything. Open Notes, tap the camera icon, select "Scan Documents," and point your phone at the page. The iPhone automatically detects the edges, crops the image, and saves it as a PDF. You can scan multiple pages in one session by tapping the plus sign after each page, then save the whole stack as a single PDF file.

The scanner works best in decent lighting and with the page flat on a surface. If you are scanning from a book or a document you cannot lay flat, hold the phone at a slight angle — the software corrects for perspective. Once you have scanned all pages, you can email the PDF, save it to iCloud Drive, or move it to your computer using AirDrop or cloud storage.

Key Takeaways

  • The Notes app scanner is built in and free — open Notes, tap the camera icon, and select "Scan Documents" to begin.
  • The iPhone automatically detects page edges, crops the image, and converts it to PDF without any manual adjustment needed.
  • You can scan multiple pages into a single PDF by tapping the plus sign after each page before saving.
  • The scanned PDF can be emailed, saved to iCloud Drive, or moved to your computer via AirDrop or a cloud service like Google Drive or Dropbox.
  • Lighting matters — scan in natural light or near a lamp, and keep the page as flat as possible for the clearest result.

Opening the Notes app scanner

Launch the Notes app on your iPhone. Create a new note or open an existing one where you want to store the scan. Tap the camera icon at the bottom of the keyboard (it looks like a small square with a mountain and sun inside). A menu appears with three options: "Take Photo," "Photo Library," and "Scan Documents." Tap "Scan Documents."

The camera view opens and shows a yellow rectangle on the screen — this is the area the iPhone is trying to detect as a document. Point your phone at the page you want to scan. The iPhone will automatically capture the image when it detects a clear page boundary. You will hear a shutter sound and see the scanned image appear on screen.

Scanning multiple pages into one file

After the first page scans, you see a thumbnail of the scan at the bottom left and a plus sign button. Tap the plus sign to scan the next page. Position your phone over the second page and wait for the automatic capture, or tap the shutter button manually if the auto-capture is slow. Repeat this for every page you need to scan.

Once you have scanned all pages, tap "Save" in the bottom right corner. The iPhone asks you to name the document and choose where to save it. The default location is the Notes app, but you can also save directly to Files or another location. The entire stack of pages becomes a single PDF file with all pages in order.

Adjusting scans before you save

Before tapping "Save," you can adjust any page. Tap a thumbnail at the bottom to select it, then use the tools that appear: you can rotate the page, delete it, or retake it. If a page came out dark or blurry, tap the page thumbnail and then the retake button (the circular arrow icon) to scan that page again without losing the others.

You can also adjust the filter after saving. Open the PDF in Notes, tap "Edit," and then tap the filter icon (three horizontal lines) to change the scan from color to grayscale or black and white. Black and white mode makes text sharper and reduces file size, which is useful if you are scanning text-heavy documents like contracts or forms.

Moving the PDF to your computer

Once the PDF is saved in Notes, you have several ways to get it to your computer. The fastest method is AirDrop if you have a Mac nearby. Open the PDF in Notes, tap "Share," and select "AirDrop." Choose your Mac from the list, and the file transfers wirelessly in seconds.

If you do not have a Mac or prefer not to use AirDrop, email the PDF to yourself. Tap "Share," select "Mail," and send it to your email address. Open the email on your computer and read the attachment. Alternatively, save the PDF to iCloud Drive, Google Drive, or Dropbox from the share menu, then access it from your computer's web browser or the desktop app for that service.

Getting the best scan quality

Lighting is the single biggest factor in scan quality. Scan in a room with natural light from a window, or position a desk lamp so light falls across the page without creating a glare or shadow. Avoid scanning directly under overhead lights, which often create uneven shadows.

Keep the page as flat as possible — use a table or clipboard rather than holding the document in your hand. If you are scanning from a book or bound document, open it as wide as it will go and position the phone so the page is as parallel to the camera as you can manage. The iPhone's perspective correction is good, but flat is always better. Hold the phone steady for a moment after positioning it; the auto-capture works best when the phone is still.

Using the Files app scanner as an alternative

The Files app also has a document scanner, and it works the same way as the Notes scanner. Open Files, navigate to the folder where you want to save the scan, tap the three dots menu, and select "Scan Documents." The scanning process is identical — the iPhone detects the page, you can add multiple pages, and you save as a PDF.

The main difference is where the file is saved. Files app scans go directly to your chosen folder in iCloud Drive or on your device, rather than into a note. Use the Files app scanner if you want to organize scans into folders from the start, or if you prefer not to use Notes.

Frequently Asked Questions

Can I scan a document that is not flat, like a page in a book?

Yes. The iPhone's perspective correction handles angled pages reasonably well. Open the book as wide as possible, position the phone at a slight angle to the page, and let the auto-capture work. The result may not be perfect, but it is usually readable. For important documents, try to flatten the page as much as you safely can.

What file format does the iPhone scanner create?

The iPhone scanner saves as PDF, which is the standard format for scanned documents. PDFs preserve the layout and are straightforward to email, print, or upload to most services. You cannot change the format directly in the Notes or Files app, but you can convert the PDF on your computer if needed.

How do I make the text in a scanned document searchable?

The iPhone scanner does not perform optical character recognition (OCR) to make text searchable. If you need searchable text, you can upload the PDF to Google Drive on your computer, and Google Drive will automatically OCR it and make the text searchable. Some third-party apps also offer OCR, but the built-in scanner does not.

Can I scan directly to my computer without using my phone's storage?

Not directly. The iPhone scanner saves to Notes or Files first. From there, you can email the PDF, save it to iCloud Drive, or use AirDrop to send it to your Mac. There is no way to scan and send directly to a Windows computer without saving to your iPhone first, but email or cloud storage makes the transfer quick.

What should I do if the iPhone does not auto-capture the page?

Make sure the page is well-lit and the edges are clearly visible against the background. If auto-capture is still slow, tap the shutter button manually instead of waiting for the automatic trigger. You can also try moving the phone slightly closer or adjusting the angle so the page fills more of the frame.
