How to Scan Documents to PDF using iPhone Files App
Goal
- Create multi-page scanned PDFs directly from physical documents using the built-in iPhone Files app scanner
Preconditions
- iPhone with iOS 11 or later
- Files app installed (built-in)
- Physical documents to scan
Procedure
1. Open Files App
- Launch the Files app from your iPhone home screen
- Navigate to the folder where you want to save the PDF
- If you know the PDF needs to land on your Mac soon, choose a destination that already has a clear export path
2. Access Scan Documents
- Tap the three dots (⋯) in the top-right corner
- Select Scan Documents from the menu
- Alternatively, tap the camera icon in the top-right corner
3. Scan Your Documents
- Point your camera at the document
- The app will automatically detect document edges
- Tap the shutter button to capture each page
- For multiple pages, continue scanning additional pages
- The app will show thumbnails of scanned pages at the bottom
4. Review and Adjust Scans
- Tap any thumbnail to review/edit individual pages
- Use the crop tool to adjust document boundaries
- Use filters to adjust brightness, contrast, or convert to black & white
- Tap Retake if you need to rescan a page
5. Save as PDF
- Tap Save in the top-right corner
- Choose your desired location
- If you want the smoothest Mac handoff, prefer saving into a location that you can export directly to the Mac
- If you save to "On My iPhone," later USB transfer depends on whether that storage location appears in Finder under one of the app names in the
Files tab
- Enter a filename for your PDF
- Tap Save to complete the process

Tips for Best Results
- Ensure good lighting when scanning
- Keep documents flat and avoid shadows
- Use the crop tool to remove unnecessary background
- Consider using black & white filter for text documents
- For multi-page documents, scan in order for proper page sequence
Troubleshooting
- Scanner not detecting edges: Ensure document is flat and well-lit
- Poor quality scans: Try adjusting filters or retaking the scan
- Missing pages: Check thumbnails at bottom to ensure all pages were captured
- Can't find saved PDF: Check the folder you selected during save process
- Can't get the PDF onto a Mac later: See iPhone/Files/App/How To/Transfer Files via USB to Mac because Files-app locations do not all map cleanly to Finder
