The iPhone Notes app has a built-in scanner you don't need to read

Your iPhone can scan documents without any extra app. Open the Notes app, tap the camera icon at the bottom of the compose window, and select "Scan Documents" from the menu. Point your phone at the document, tap the shutter button when the frame turns yellow, and the phone will automatically crop and enhance the image. You can scan multiple pages into a single note, then save or share the result as a PDF.

This built-in scanner works on any iPhone running iOS 13 or later. The scans are sharp enough for most purposes — reading, storing, or sending to someone else. If you need the document to be searchable (so you can find text inside it later), you will need to use optical character recognition, which is a separate step covered below.

Key Takeaways

  • The Notes app's document scanner is free and built into every recent iPhone; you do not need to read anything.
  • The phone automatically detects the document edges, straightens the image, and enhances contrast so text is readable.
  • You can scan multiple pages into one note and save the result as a PDF file.
  • Making a scanned document searchable by text requires optical character recognition, which Notes does not do — you will need a separate app or service for that.
  • Scanned documents saved as PDFs can be emailed, uploaded to cloud storage, or printed from your computer.

Step-by-step: scanning a single document

Open the Notes app and create a new note or open an existing one. Tap the camera icon at the bottom of the keyboard (it looks like a small square with a camera inside). A menu will appear with two options: "Take Photo or Video" and "Scan Documents." Tap "Scan Documents."

Hold your iPhone about 6 to 12 inches above the document and point the camera at it. The screen will show a live preview. When the document is in frame and the lighting is good, the frame around the document will turn yellow. Tap the shutter button (the white circle at the bottom center) to capture the scan. The phone will automatically crop the edges and enhance the image.

After the scan is captured, you will see a preview with adjustment handles at each corner. You can drag these handles to adjust the crop if the phone got the edges wrong. Tap "Keep Scan" to save it to the note. If you need to scan more pages, tap "Scan Another Page" and repeat the process. When you are done, tap "Save" to finish.

Saving and sharing your scanned document

Once your scans are saved in a note, you can export them as a PDF. Open the note, tap the three dots at the top right, and select "Collaborate" or scroll down to find "Share Note." From there, tap "Save PDF to Files" or choose another sharing option like email or cloud storage.

If you want to save the PDF to your iPhone's Files app, tap "Save PDF to Files," choose a folder, and tap "Save." The PDF will be stored in that folder and you can access it anytime. If you want to email the PDF, tap "Mail" instead, and your email app will open with the PDF attached and ready to send.

PDFs created this way can be opened on any computer or phone. You can print them, upload them to cloud storage like Google Drive or iCloud, or send them to someone else. The file size is usually small enough to email without problems.

Making scanned text searchable

The Notes app does not automatically make scanned documents searchable by the text inside them. If you need to search for words within a scanned PDF later, you will need optical character recognition (OCR). This is a process that reads the image and converts it to actual text that a computer can search.

Several apps offer OCR for free or for a small cost. Adobe Acrobat Reader (free version) can recognize text in PDFs you upload. Google Drive also has built-in OCR — you can upload a PDF to Google Drive, right-click it, select "Open With," choose "Google Docs," and the text will be extracted and searchable. Microsoft OneNote is another option that recognizes text automatically when you save a scanned image.

If you scan documents regularly and need them searchable, consider using one of these apps from the start instead of Notes. The workflow is similar, but the text recognition happens automatically.

Improving scan quality in poor lighting

The Notes scanner works best in natural light or bright indoor lighting. If the room is dim, the scanned image may be blurry or hard to read. Move closer to a window or turn on overhead lights. Avoid shadows falling across the document.

If you are scanning a document with very light text or a faded original, the phone's automatic enhancement may not be enough. After you capture the scan, the preview screen shows adjustment sliders. Tap "Adjust" and use the sliders to increase contrast or brightness. Drag the contrast slider to the right to make text darker and the background whiter.

Glossy or shiny paper can cause glare. Tilt the phone slightly to avoid reflecting light directly back into the camera. If glare is still a problem, try scanning from a slightly different angle or moving the light source.

Scanning documents with multiple pages

To scan a multi-page document, follow the same process but tap "Scan Another Page" after each page instead of "Save." The phone will add each new page to the same note. You can scan as many pages as you need — there is no limit.

After you have scanned all pages, review them in the note. If one page came out blurry or cropped wrong, you can tap on that page and retake it. When everything looks good, save the note and export it as a PDF. The PDF will contain all pages in order.

If you are scanning a long document, take breaks between pages to avoid hand fatigue. The phone will not time out or lose your progress if you pause between scans.

Troubleshooting common scanning problems

If the "Scan Documents" option does not appear in your Notes app, your iPhone may be running an older version of iOS. Update to iOS 13 or later by going to Settings, tapping General, and selecting Software Update. The scanner is not available on iPhones older than the iPhone XS or iPhone XR.

If the scanned image is blurry, the phone may have moved during the capture. Hold the phone as still as possible and tap the shutter button quickly. Make sure the document is flat and not wrinkled or folded. If the document itself is damaged or faded, no phone scanner will make it perfectly clear.

If the automatic crop is cutting off part of the document, manually adjust the corner handles on the preview screen before saving. If the text is too light to read after scanning, use the Adjust sliders to increase contrast. If the PDF file is too large to email, try compressing it in the Files app or using a free online PDF compressor before sending.

Frequently Asked Questions

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

Yes, but the quality will be lower. The scanner works best on flat documents. If you are scanning from a book or curved surface, try to flatten it as much as possible without damaging it. The phone may struggle to auto-crop the edges, so you will likely need to adjust them manually.

What file format does the Notes app save scans in?

The Notes app saves scans as PDF files. PDFs can be opened on any computer, phone, or tablet. If you need a different format like JPG or PNG, you can convert the PDF using a free online converter or a dedicated app.

Can I edit a scanned document after I save it?

You can edit the note itself — add text, delete pages, or retake a page. Once you export it as a PDF, you cannot edit it in the Notes app. To edit a PDF, you will need a separate app like Adobe Acrobat Reader or Preview on a Mac.

Is there a limit to how many pages I can scan into one note?

There is no hard limit, but very large notes may slow down your phone. If you are scanning more than 50 pages, consider splitting them into separate notes to keep file sizes manageable.

Do I need an internet connection to scan documents?

No. The Notes app scanner works completely offline. You only need internet if you want to upload the PDF to cloud storage or email it afterward.
