How to Scan Multiple Pages into One PDF on iPhone

Emailing someone five separate scan files is a mess. Here's how to capture an entire multi-page document as one clean, ordered PDF on your iPhone.

The quick answer

Use batch scanning: capture each page one after another in a single session, and the app saves them together as one multi-page PDF — in order, ready to share as a single file.

Step-by-step: batch scan to a single PDF

1. Open Mobile Document Scanner and start a batch scan.
2. Scan page 1. Edge detection captures it automatically; the page count appears on screen.
3. Flip to the next page and keep going. Each capture is appended in sequence — no need to stop between pages.
4. Review and reorder. Captured a page twice or out of order? Rearrange, rotate, or delete pages before saving.
5. Save as one PDF and share it as a single attachment.

Combining scans you already made

Already have separate PDF files that should be one document? You don't need to rescan — merge them directly. See how to merge PDF files on iPhone.

Keeping large scans shareable

Multi-page scans with photos can get heavy. If your PDF is too large to email, compress it first — the guide on compressing a PDF on iPhone covers it in two taps.
