Combine scanned pages into one PDF
Many scanners and phone scanning apps save each page as its own PDF. A five-page contract becomes five files, and the person receiving it has to open them one by one and guess the order.
Merge PDF joins those single-page files into one document. Files are joined in the order you add them, and the work happens in your browser, so private paperwork is not uploaded.
A note on order: most scanning apps number files by the time they were created, so pages scanned out of sequence will also be listed out of sequence. Before you merge, compare the list with the physical document, particularly for contracts and forms where a missing or swapped page can cause the whole submission to be rejected. If a page was scanned twice, remove the duplicate from the list rather than deleting it from the merged file later.
Step by step
- Open Merge PDF and add the scanned files in page order (add them one at a time if your file names don't sort correctly).
- Check the list. If a file is out of place, remove it with its remove button and add it again at the right point.
- Merge and download the combined PDF.
- Scroll through the result to confirm every page is present and upright.
Tips
- Name scans with numbers (page-01, page-02) before adding them; it makes ordering much quicker.
- If one scan came out sideways, fix it with Rotate PDF after merging.
- Large scanned documents can be shrunk afterwards with Compress PDF.
Questions
- Can I merge scans from different devices?
- Yes. Any PDF files can be combined, wherever they were scanned.
- Does merging reduce scan quality?
- No. Pages are copied into the new file as they are; nothing is re-compressed.
- My scans are JPG images, not PDFs. What should I use?
- Use JPG to PDF, which turns several photos into one PDF directly.
