How to Scan Multiple Pages Into One PDF (Free)

A contract is twenty pages. A mortgage file is forty. Creating a separate PDF for each page defeats the whole point — a multi-page document should come out as a single PDF you can email, file, or sign as one object. Your phone can produce exactly that, for free, without extra apps.

Here is how to scan multiple pages into one PDF in a single pass.

Scan all pages before downloading

The trick is not to download after every page. A scanner that keeps the camera open between captures adds each page to the same working document, so the whole stack becomes one file at the end:

1. 1Open the Scan PDF tool on your phone — the camera stays live the whole time.
2. 2Frame the first page, let auto-detection outline it, and save it from the review screen.
3. 3Turn to the next page and repeat; the counter up top shows the growing page count.
4. 4If a page is sideways or the lighting is bad, fix it with rotate or a filter before saving.
5. 5When every page is in, tap Done.
6. 6Download the finished PDF — it contains all the pages as one document.

• Tap the thumbnail strip to jump back and check pages you already scanned
• Rework a page any time by rescanning and saving again
• The order you save pages in becomes the order in the PDF

Two ways to capture each page

For speed, leave auto-scan on and simply hold the page steady — the detector waits for the frame to settle, then captures on its own. For tricky pages with glare or clutter, switch auto-scan off and tap the shutter instead; you still get the review screen either way.

Keep the file size in check

A thirty-page scan adds up quickly, especially when pages are photo-heavy. Run the finished PDF through a compressor and pick the Recommended level — text usually stays sharp while the file shrinks by over half, which also makes it easy to email as one attachment.
