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, and select "Scan Documents" from the menu. Point your phone at the document, and the iPhone will automatically detect the edges and take a photo. You can scan multiple pages into a single document by tapping the plus button after each page.

After you finish scanning, the app shows you all the pages in order. You can rotate, delete, or re-scan any page before saving. When you are done, tap "Save" and choose where to store it — Notes saves the scan as a PDF by default. You can then share it directly from Notes using the share button, or open it later to send it somewhere else.

This method works best for documents that fit on a standard page — letters, receipts, contracts, forms. If you are scanning a book or something with curved pages, the automatic edge detection may struggle, and you might need to adjust the corners manually after the scan.

Key Takeaways

  • The Notes app on every iPhone includes a document scanner that creates PDFs without any additional apps or cost.
  • Tap the camera icon in Notes, select "Scan Documents," and the iPhone automatically detects page edges and straightens the image.
  • You can scan multiple pages into one PDF by tapping the plus button after each page, then save the entire document at once.
  • The scanned PDF saves directly to Notes and can be shared via email, Messages, or moved to cloud storage like iCloud Drive or Google Drive.
  • For curved or bent documents, you may need to manually adjust the corners after scanning because automatic detection works best on flat pages.

Scanning Multiple Pages Into One Document

When you scan the first page, the iPhone shows it on your screen with corner handles. Tap "Keep Scan" to accept it. The app then returns to the camera view so you can scan the next page when ready. Each new page appears below the previous one in the same document. You can scan as many pages as you need this way — there is no limit.

If you make a mistake, tap the thumbnail of any page and choose "Delete" or "Retake" before saving. You can also reorder pages by dragging them, though Notes does not have a built-in way to rotate individual pages after you save. If a page ends up sideways, you will need to delete it and scan again.

Saving and Sharing Your Scanned Document

After you finish scanning all pages, tap "Save" at the bottom right. Notes asks you to name the document and choose which note to save it to. The scan becomes a PDF attached to that note. From there, you can tap and hold the PDF thumbnail to see options: you can share it via email, Messages, AirDrop, or copy it to another app.

If you want the PDF in a different location — like your Files app, Google Drive, or Dropbox — tap "Share" and select the app you want to send it to. Most cloud storage apps will let you save the PDF directly to a folder. This is faster than scanning to Notes and then moving it later.

Using the Files App to Scan and Organize

If you prefer to keep scans organized in one place rather than scattered through Notes, you can use the Files app instead. Open Files, navigate to a folder where you want to save the scan, tap the three dots at the top right, and look for a "Scan Documents" option if your iPhone supports it. Not all iOS versions have this feature in Files, so if you do not see it, stick with Notes.

Alternatively, scan in Notes and then move the PDF to Files afterward. Open the note with your scan, tap and hold the PDF, select "Share," choose "Save to Files," and pick your destination folder. This takes one extra step but gives you a cleaner file structure if you are scanning many documents.

Improving Scan Quality and Handling Problem Documents

The iPhone's automatic edge detection works well in good lighting. If your scan comes out dark, blurry, or with shadows, try scanning again in brighter light or near a window. Avoid scanning directly under overhead lights, which can create glare. If the document has a glossy surface, angle your phone slightly to reduce reflection.

For documents with text that is small or faint, get as close as the camera will focus — usually about 6 to 8 inches away. The iPhone will still detect the page edges even if you are zoomed in. After scanning, you can check the quality by opening the PDF in Notes or the Files app. If it is unreadable, delete it and try again with better lighting or a closer angle.

If you are scanning something that is not a flat document — like a page in a book, a curved receipt, or a folded letter — the automatic edge detection may not work correctly. In that case, manually adjust the corner handles after the scan to crop out the background and straighten the image as much as possible.

Sending Your Scan to a Computer

Once your PDF is saved in Notes or Files, you can move it to your computer in several ways. The simplest is email: open the note or file, tap Share, select Mail, and send it to yourself. Open the email on your computer and read the attachment.

If you use iCloud, any PDF saved to iCloud Drive on your iPhone automatically appears on your computer in the iCloud Drive folder. You can also use AirDrop if you have a Mac nearby — tap Share, select AirDrop, and choose your computer. For Windows computers, email or cloud storage (Google Drive, Dropbox, OneDrive) is usually the fastest route.

Frequently Asked Questions

Can I scan a document without using Notes?

Yes. Many third-party apps like Adobe Scan, Microsoft Lens, and Scanbot also scan documents on iPhone. These apps often have extra features like automatic cloud backup or better text recognition, but they require downloading and may ask for a subscription. The Notes app is free and built in, so it is the easiest starting point.

What format does the iPhone save scans in?

Notes saves scans as PDF files by default. PDFs work on any computer or phone and preserve the document's layout. Some third-party scanning apps let you save as JPEG or other formats, but PDF is the standard for documents you plan to share or store long-term.

Can I edit text in a scanned document?

Not directly in Notes. A scanned document is an image of the page, not editable text. If you need to edit the content, you can use OCR (optical character recognition) apps like Adobe Acrobat or Microsoft Word to convert the scan to editable text, but these usually require a subscription or in-app purchase.

Why does my scan look crooked or have shadows?

Shadows usually mean uneven lighting — try scanning near a window or in brighter light. Crooked scans happen when you angle the phone or the document is not flat. Hold the phone directly above the document and keep it parallel to the page. If the automatic edge detection still misses, adjust the corners manually before saving.

Can I scan a document that is larger than a standard page?

You can scan it, but the iPhone will crop it to what fits in the frame. For large documents like posters or blueprints, you would need to scan multiple overlapping sections and stitch them together, which Notes does not do automatically. A dedicated scanning app or a flatbed scanner would be better for that job.
