How to scan multiple pages into one PDF (no upload)

18 October 2026 · 5 min read

To scan multiple pages into one PDF, use a scan mode that keeps adding pages to the same document and save only once at the end: Scan Documents in the iPhone Notes or Files app, Scan in Google Drive on Android, Import from Scanner with Combine into single document in Preview on a Mac, or the multi-page PDF setting of your scanner's software on Windows. If you already have the pages as separate files, merge them: Images to PDF for photos and JPGs, Merge PDFs for separate PDFs. Both run in the browser without uploading the scans.

The short version

1. Choose PDF as the format, not JPEG or PNG. Image formats always give one file per page.
2. Turn on the multi-page option (it has a different name in every app; see below) and scan every page before saving.
3. Already have separate files? Don't scan again. Combine them into one PDF afterwards.
4. Then tidy up: fix the page order, compress the file if it is too big to send, and run OCR if it needs to be searchable.

How do I scan multiple pages into one PDF on an iPhone?

1. Open the Notes app and start a new note, tap the camera (or attachment) button and choose Scan Documents. In the Files app, tap the More button (the three dots) and choose Scan Documents instead.
2. Hold the phone over the first page. It captures the page by itself, or you tap the shutter.
3. Turn to the next page and keep going: every capture is added to the same scan.
4. Tap Save when the last page is in. Files saves it straight away as one PDF; in Notes, open the scan and share it as a PDF.

Before saving you can tap a thumbnail to retake, crop or rotate a page.

How do I scan multiple pages into one PDF on Android?

1. Open the Google Drive app, tap + New and choose Scan.
2. Photograph the first page and accept it.
3. Tap + to add the next page, and repeat for each page.
4. Tap Save: Drive stores all pages as one PDF in the folder you pick.

Some phones have the same function in their own camera or file app; look for "scan document" or "multi-page". If your phone only gives you separate photos, combine them with Images to PDF as described below.

How do I scan multiple pages into one PDF on a Mac?

1. Put the first page on the scanner, open Preview and choose File → Import from Scanner, then your scanner.
2. Click Show Details if you only see a small window. Set the format to PDF and tick Combine into single document.
3. Scan the first page, swap in the next one and scan again. With a document feeder, load the whole stack and scan once.
4. Save the result. You can drag thumbnails in the sidebar to change the order first.

The same checkbox is in the Image Capture app, which is the fallback when Preview doesn't list your scanner. Labels can differ slightly between macOS versions and scanner drivers.

How do I scan multiple pages into one PDF on Windows?

It depends on your scanner's software more than on Windows itself. In the free Windows Scan app, set the file type to PDF; depending on the scanner and driver, you then get an option to add more pages to the same file before saving. Most scanner makers' own apps have the same thing, usually called "multi-page PDF", "Add page" or "Scan more". A scanner with a document feeder is easiest: load all pages and they arrive as one PDF.

If your software only saves one file per page, that's fine. Scan everything, then merge the files in one step, as below.

How do I merge pages I already scanned separately?

This is the most common situation: a folder of scan001.pdf, scan002.pdf, or a camera roll full of photos of pages. Both tools below run inside the browser tab, so the scans, which are often IDs, contracts or medical papers, aren't uploaded anywhere.

If the pages are photos or images (JPG, PNG, HEIC from an iPhone, WebP):

1. Open Images to PDF and choose all the images at once.
2. Pick a page size: each page fitted to its image, A4 or US Letter.
3. Download the PDF. Each image becomes one page, in the order the files were handed over, so name them so they sort correctly (01, 02, 03 …).

If the pages are separate PDFs:

1. Open Merge PDFs and drop all the files.
2. Keep the order shown, or type a new one as numbers, for example 2, 1, 3.
3. Download one combined PDF.

A mix of both? Turn the images into a PDF first, then merge it with the other PDFs. On a Mac, Preview can also do the PDF merge: open the first file, show the thumbnails and drag the others into the sidebar. More on that in how to combine PDF files into one.

What should I fix after scanning?

• Pages in the wrong order or upside down: Reorder pages and Rotate pages. A blank back side scanned by accident goes with Delete pages.
• The file is too big to email or upload: scans are pictures, so ten pages can be many megabytes. Compress PDF has a strong mode that re-renders pages as smaller images; see compressing a PDF for email.
• You can't search or copy the text: a scan has no text layer. OCR adds one for English and German documents and leaves the page images as they are; details in scan to searchable PDF.
• It contains things the recipient shouldn't see: run OCR first, then the Redactor.

Questions people ask

How do I scan multiple pages into one PDF?

Use a scan mode that keeps adding pages to the same document: Scan Documents in the iPhone Notes or Files app, Scan in the Google Drive app on Android, File > Import from Scanner with Combine into single document in Preview on a Mac, or the multi-page PDF option of your scanner's software on Windows. Scan every page, then save once.

How do I merge scanned documents into one PDF?

If the scans are separate PDFs, merge them with a tool such as macOS Preview or the pdfagents.ai Merge tool. If they are photos or JPG/PNG/HEIC images, turn them into one PDF with Images to PDF, which puts one image on each page. Both pdfagents.ai tools run in the browser, so the scans are not uploaded.

Why does my scanner save every page as a separate file?

Usually because the file format is set to JPEG or PNG, or the PDF option is set to single-page. Switch the format to PDF and look for a setting such as multi-page PDF, Combine into single document or Add page. If the separate files already exist, merge them afterwards instead of scanning again.

Can I make the scanned PDF searchable?

Yes, with OCR. A scan is a picture of each page, so its text cannot be searched or copied until OCR adds a text layer. The pdfagents.ai OCR tool does this in the browser for English and German documents and keeps the page images as they are.
