Merge Scanned Documents into One PDF — Free
Overview
Office scanners, phone scanning apps (CamScanner, Adobe Scan, Apple Notes), and flatbed scanners all produce separate PDF files per scan session. If you need all pages in one document — a complete ID set, a full contract, a multi-page application form — merge them here. No limit on file count, completely free.
How to Use This Tool
Upload your scanned PDFs on the Merge page. Drag to set the correct page order. Click Merge and download. If some pages came out sideways, use the Rotate tool to correct their orientation before or after merging. Compress the output to reduce size — scanned images are often large.
Ready to get started? It's free, no registration required, and your files never leave your device.
Merge PDF →Frequently Asked Questions
Can I merge PDFs from different scanning apps?
Yes. PDFs from any source — CamScanner, Adobe Scan, iPhone scanner, or physical office scanners — can all be merged together.
Why is my merged scanned PDF so large?
Scanned PDFs store pages as images, which are significantly larger than text-based PDFs. After merging, run the result through the Compress tool to reduce file size.
Can I fix sideways scanned pages before merging?
Yes. Use the Rotate tool to correct the orientation of individual scanned pages, then merge the corrected PDFs.
