The fastest way: use the built-in Notes app

Your iPhone has a document scanner built into the Notes app — you do not need to download anything. Open Notes, start a new note, tap the camera icon at the bottom, and select "Scan Documents" from the menu. Point your phone at the document, and the camera will detect the edges automatically and snap a photo when it is ready. You can scan multiple pages into a single note by holding the phone steady as each page is captured.

After you scan, the app shows you a preview of each page. You can rotate, crop, or delete pages before saving. The scanned pages are stored as a PDF inside that note. To save the PDF to your Files app or send it elsewhere, tap the share icon (the arrow pointing out of a box), then choose "Save PDF to Files" or email it directly.

This method works on iPhone XS and newer. If you have an older model, you can still scan documents using the Camera app directly — point it at the document and take a photo, then use a third-party app to convert the image to a PDF.

Key Takeaways

  • The Notes app has a built-in document scanner that detects page edges automatically and saves scans as PDFs without any extra apps.
  • You can scan multiple pages in one session, then rotate, crop, or delete individual pages before saving the final PDF.
  • Scanned PDFs can be saved to your Files app, emailed, or shared with other apps directly from Notes.
  • If your iPhone is older than XS, you can take photos with the Camera app and convert them to PDFs using third-party apps like Adobe Scan or Microsoft Lens.

Using the Camera app and a third-party scanner

If you prefer a dedicated scanning app or need more control over the final image, Adobe Scan and Microsoft Lens are the most common choices. Both are free to download from the App Store. They work similarly to Notes: you point your phone at a document, the app detects the edges, and you can scan multiple pages in one session.

Adobe Scan saves scans as PDFs and can also recognize text in the document (called OCR, or optical character recognition), which means you can search for words inside the PDF later. Microsoft Lens does the same and also lets you convert scanned documents into editable Word or Excel files. Both apps let you save scans to cloud storage like Google Drive or OneDrive, which is useful if you want to access them from a computer.

The trade-off is that these apps take up storage space on your phone and may ask you to create an account. For most people, the Notes app scanner is enough. Use a third-party app only if you need OCR, cloud backup, or conversion to other file formats.

How to get the clearest scan

The quality of your scan depends mostly on lighting and how steady you hold the phone. Scan in natural light or under a bright lamp — shadows and glare make text harder to read. Hold the phone directly above the document at a slight angle (not flat against the page), and keep your hands as still as possible. Most scanner apps will show you when the image is in focus before you take the shot.

If the document has small text or is printed on thin paper that shows text from the back, take the photo in good light and let the app adjust the contrast. The Notes app and third-party scanners both clean up the image automatically — they remove shadows, straighten the page, and boost contrast so the text is dark and readable.

Saving and organizing your scans

Scans from the Notes app stay inside that note unless you export them. To keep them organized, create separate notes for different documents — one for receipts, one for medical records, and so on. When you need to send a scan to someone, open the note, tap the share icon, and choose "Save PDF to Files" or email it directly.

If you use a third-party app like Adobe Scan or Microsoft Lens, both let you organize scans into folders within the app itself. You can also save them to cloud storage automatically — Adobe Scan can back up to Google Drive or Dropbox, and Microsoft Lens backs up to OneDrive. This way, your scans are safe even if you delete them from your phone.

Converting scans to other formats

By default, all iPhone scanners save documents as PDFs. If you need a different format — like a Word document, an image file, or an Excel spreadsheet — your options depend on which app you used.

Microsoft Lens can convert scans directly to Word or Excel files, which is useful if you need to edit the text. Adobe Scan can extract text and save it as a searchable PDF, but to convert to Word you would need to use a separate tool like Adobe's online converter or a free service like Smallpdf. If you just need an image file (JPG or PNG), you can take a regular photo with the Camera app instead of using a scanner app.

Troubleshooting common scanning problems

If the Notes app does not recognize your document as something to scan, make sure you are in good lighting and the document is flat and fully visible in the frame. The app needs to see clear edges to detect the page. If it still does not work, try opening the Camera app directly, taking a photo of the document, and then using a third-party scanner app to convert that photo to a PDF.

If your scans are blurry, the problem is usually movement or poor lighting. Steady your phone on a table or hold it very still, and move to a brighter location. If text is too light to read, the app may have adjusted the contrast too much — try retaking the scan in slightly different lighting.

If you cannot find your scans after saving them, check the Files app under "On My iPhone" or "iCloud Drive" depending on where you saved them. Scans from Notes stay in the Notes app unless you export them. Scans from third-party apps usually appear in the app itself and in whatever cloud storage you connected.

Frequently Asked Questions

Can I scan a document that is longer than one page?

Yes. In the Notes app, keep the phone steady and tap the shutter button for each page — the app will add them all to the same note as a multi-page PDF. Third-party apps like Adobe Scan and Microsoft Lens work the same way. You can scan as many pages as you need in one session.

What if my document has handwriting or signatures?

Scanners capture handwriting just like printed text. The image quality depends on lighting and how dark the handwriting is. If you need to search for words later, use an app with OCR like Adobe Scan or Microsoft Lens, though OCR works better on printed text than handwriting.

Can I edit a scanned document after I save it?

A scanned PDF is an image, not editable text. If you need to change the words, you would have to retype them. Microsoft Lens can convert scans to Word files, which you can then edit. Otherwise, use a PDF editor app or convert the scan to text using an online OCR tool.

Is there a limit to how many documents I can scan?

No. The Notes app and free versions of Adobe Scan and Microsoft Lens have no limit on the number of documents you can scan. The only limit is storage space on your phone or in cloud storage.

Do I need an internet connection to scan a document?

No. The Notes app and most scanner apps work offline — they scan and save to your phone without needing WiFi or cellular data. You only need internet if you want to upload scans to cloud storage or email them.
