How to Scan Multiple Pages into One PDF (Printer and Phone)

To scan multiple pages into one PDF, feed your document stack into an automatic document feeder or use manufacturer scanning software for flatbed combining. On Windows, use Brother iPrint&Scan or HP Smart. On iPhone, use the Files app to save directly to storage. On Android, use the Google Drive scanner.

Scanner Hardware Basics: ADF vs Flatbed Glass

When creating multi-page PDF files from physical paperwork, the hardware mechanism on your multifunction printer dictates the scanning workflow:

• Automatic Document Feeder (ADF): Found on office all-in-one printers, an ADF pulls a stack of individual loose sheets sequentially through a motorized roller system past a stationary scanning sensor. An ADF handles twenty to fifty pages in a single uninterrupted operation, producing an integrated multi-page PDF automatically.
• Flatbed Glass: A stationary glass platen where documents are placed face-down one sheet at a time. While flatbed scanning delivers superior optical clarity for bound books, delicate receipts, and photos, combining separate pages into a single PDF file requires software that prompts for the next sheet before compiling the final document.

Windows: Why Windows Scan App Requires an ADF and How to Combine Flatbed Pages

Users frequently encounter frustration with the native Windows Scan application downloaded from the Microsoft Store. Understanding its design limitations saves considerable time.

The Limitation of Windows Scan

When using the native Windows Scan app, the File type menu allows selecting PDF. However, if your scanner is a flatbed without an ADF, or if you select Flatbed as the source, the application saves each scan immediately as an isolated file (Scan.pdf, Scan (1).pdf, etc.). The native Windows Scan interface does not offer an "Add Page" or prompt-for-next-sheet dialogue. It compiles a multi-page PDF only when the source is set to Feeder.

How to Combine Flatbed Pages Using Manufacturer Software

To combine sequential flatbed scans into a single PDF document on Windows, bypass the generic Windows app and utilize your printer manufacturer dedicated utility:

Option A: Brother iPrint&Scan (Windows)

1. Open Brother iPrint&Scan on your PC and click Scan.
2. Under Document Size, select A4 or Letter, and choose PDF as the file format.
3. Set Scan Type to Document, and place your first sheet on the flatbed glass.
4. Click Scan. After the first page finishes, the preview screen displays an Add Page button (a sheet with a plus icon).
5. Place your second sheet on the glass, click Add Page, and repeat for all subsequent sheets.
6. Once all pages appear in the thumbnail ribbon, click Save to PC, name your file, and verify that PDF is selected. Brother compiles all captured pages into a single file.

Option B: HP Smart / HP Scan Assistant

1. Launch HP Smart and click the Scan tile.
2. Select Source: Flatbed and choose PDF under Output.
3. Click Scan. When the initial page renders, click the + Add button in the top left corner of the preview pane.
4. Place the next page on the scanner glass and click Scan.
5. Once your document set is complete, click Save in the bottom right corner.

macOS: Scanning Multi-Page PDFs with Apple Image Capture

Apple macOS includes a robust scanning utility called Image Capture built directly into the operating system that natively supports combining flatbed and ADF scans without third-party software.

1. Place your first page on the flatbed glass or load your stack into the document feeder.
2. Open Image Capture from your Applications folder (or press Command + Space, type Image Capture, and press Enter).
3. Select your scanner from the left-hand Devices or Shared sidebar.
4. If you only see a basic preview, click Show Details at the bottom right.
5. In the details pane:

• Set Kind to Black & White or Color.
• Set Resolution to 300 dpi.
• Under Format, select PDF.
• Crucial Step: Check the box labelled Combine into single document.

1. If scanning via flatbed, click Scan. Image Capture will scan the page. To add further sheets, simply replace the paper on the glass and click Scan again.
2. Image Capture appends each subsequent scan into the same master PDF until you close the application or change the destination folder.

iPhone and iPad: Files App vs Apple Notes

Many iPhone users use Apple Notes to scan documents. While Apple Notes functions well for personal notes, it embeds the resulting scan inside an .apple.notes database entry rather than creating an immediately shareable standalone PDF.

The Superior Method: Scanning Directly via Apple Files

The native Files app on iOS and iPadOS includes an integrated document scanner that saves a clean, industry-standard PDF directly to iCloud Drive or On My iPhone.

1. Open the Files app on your iPhone or iPad.
2. Navigate to the specific folder where you want to save the final PDF (for example, iCloud Drive > Documents).
3. Tap the More button (the circle with three horizontal dots) in the upper-right corner of the screen.
4. Select Scan Documents from the popup menu.
5. Position your iPhone camera over the document. By default, iOS operates in Auto mode, automatically detecting page edges, flattening perspective distortion, and capturing the image.
6. Swap pages. The camera will continue snapping subsequent pages automatically.
7. If lighting is dim, switch the shutter button to Manual, snap the photo, and drag the corner circles to align paper boundaries.
8. When all pages are captured, tap Save in the lower-right corner. The app immediately writes a single, multi-page PDF to your folder, ready to email, upload, or AirDrop.

Android: Multi-Page Scanning via Google Drive

Every Android smartphone with Google Play Services features native multi-page PDF creation through the pre-installed Google Drive application.

1. Open the Google Drive app on your Android smartphone.
2. In the bottom right corner, tap the + (Create) button, or tap the floating Camera shortcut.
3. Select Scan (camera icon).
4. Frame the first sheet in your camera viewfinder and tap the blue shutter button.
5. Review the scan. Use the crop tool to adjust edges or select colour filters (Greyscale, Colour, or Black & White).
6. To Add More Pages: Tap the + icon in the bottom-left corner of the screen. Frame and capture your next sheet.
7. Repeat this step for all remaining sheets. A counter at the top displays your active page total (e.g., "3 of 3").
8. Tap Save in the upper-right corner. Enter a document title, choose your Google Drive folder, and tap Save. Google Drive saves your capture as a searchable, compact PDF.
