How to scan multiple pages into one PDF
To scan multiple pages into one PDF, the whole trick is to add every page to the same document before you export — instead of saving each page separately and trying to stitch them together later. Here is how to do it on Android and in ScannerFlow, keep the pages in order, and end up with a single tidy file.

The one thing that matters
One session, one file
The reason people end up emailing five separate photos is that they tap “save” after every page. The fix is simple: keep the scan session open and add each page to it, then export once at the end. Every capable scanner supports this — the button is just easy to miss.
In ScannerFlow
Build a multi-page PDF in four taps
- 1
Start a new scan
Open ScannerFlow and tap the scan button. Capture page one — edge detection frames and straightens it automatically.
- 2
Keep capturing to add pages
After each page, tap the shutter again. Every capture is appended to the same document, so you are building one file, not a folder of photos.
- 3
Fix the order and remove duds
Drag pages to reorder them, and delete any blurry or duplicate shots. Getting the sequence right now saves an awkward re-send later.
- 4
Export as a single multi-page PDF
Tap export and choose PDF. All pages come out as one file, in order, with on-device OCR making the text searchable.
With the built-in Android scanner
The same idea in Google Drive
Free and pre-installed — the key is the 'Add page' button between captures.
- 1
Open Google Drive → "+" → Scan
The built-in scanner opens the camera. Capture your first page and crop it to the edges.
- 2
Tap the "+" to add each page
Look for the "Add page" (plus) icon after a capture. Repeat for every page before you finish — this is the step people miss.
- 3
Save once, at the end
Only tap Save/Done after the last page. Drive bundles everything you captured in that session into a single PDF.
Drive is great for a handful of pages. For longer documents — where you want to reorder pages, drop bad shots, keep the text searchable, and keep the file small — a dedicated scanner handles the housekeeping better. More context in our scan-to-PDF on Android guide.
Get it right the first time
Three habits for clean multi-page scans
Scan in reading order
Capture pages front-to-back as you go. It is far easier than reshuffling twenty thumbnails afterward.
Keep the lighting consistent
Same spot, same light, same filter for every page, so the finished PDF reads as one document rather than a patchwork.
Review before you export
Skim the page order and delete blurry or duplicate captures. A ten-second check beats a “resending — ignore the last one” email.
Then do more with it
A multi-page PDF you can actually use
Once your pages are in one file, ScannerFlow makes the whole thing searchable with on-device OCR, and the AI document scanner can summarize a long report or answer questions across every page. See the scan-to-PDF feature for the full export workflow.
Multi-page PDF — FAQ
How do I combine multiple scanned pages into one PDF?
Scan them in a single session and add each page to the same document before you export. In Google Drive’s scanner, tap the "+" (Add page) icon after each capture, then Save once. In ScannerFlow, keep tapping the shutter to append pages, reorder them, and export the whole set as one multi-page PDF.
Can I add a page to a PDF I already scanned?
Yes. Open the existing document in ScannerFlow and scan another page into it, then re-export. This is much cleaner than scanning a stray page separately and trying to merge two PDFs afterward.
How do I change the page order in a scanned PDF?
Before exporting, drag pages into the order you want in the scan preview. In ScannerFlow you can reorder and delete pages in the same screen where you review them, so the exported PDF matches the original document’s sequence.
Is there a limit to how many pages I can scan into one PDF?
For practical purposes, no — you can build long documents. Very large scans get big, so scanning in grayscale and letting the app compress the file keeps a long multi-page PDF email-friendly. See our guide on reducing a scanned PDF’s file size.
Is ScannerFlow free for multi-page PDFs?
ScannerFlow is free to download and free to try. Multi-page PDF export is part of the optional subscription, so you can scan and preview a multi-page document before deciding. There is no "free unlimited" plan.
