How to merge PDF files

  1. Select your PDFs

    Choose the files, or drop them onto the page. Each one shows a preview of its first page and its page count.

  2. Put them in order

    Drag files by their handle, or use the up and down arrows. Add more files, or remove any you don't need. Start over clears the list.

  3. Merge

    Select Merge PDF. It runs in your browser, and keeps working offline once your files are chosen.

  4. Check and fix the pages

    Select pages to turn, move or remove them. Open a page to zoom in or crop it, or make every page A4 or Letter. Then select Apply changes.

  5. Download

    Download merged.pdf. Your original files aren't changed.

How merging works

Merging joins the pages of several PDFs into one file, in the order you choose. It’s useful when a form or email asks for a single file: certificates for a job application, scanned pages of one document, or receipts for an expense claim. After merging, you can check every page, turn sideways scans upright, remove pages you don’t need and make every page the same size, all before you download.

certificate.pdf comes first, so its pages start merged.pdf. Swap the order to see the result change.

Tips for a clean result

  • Order matters

    The merged file follows your list from top to bottom. You can still move pages around after merging.

  • Fix sideways scans

    Phone scans of ID cards and certificates often come out sideways. Select those pages and rotate them before you download.

  • Same size for printing

    If your files are different sizes, choose A4 or Letter under Page size. Each page is scaled to fit, centred, with a small margin.

  • Size adds up

    The merged file is about as large as all your files together. If an upload limit is strict, compress scanned images first.

Questions

Does this upload my files?

No. Your PDFs are read and joined inside your browser, and the result is saved straight to your device. You can check this in your browser's Network tab: no file is uploaded.

Does it work offline?

Yes, once your files are chosen. The page loads its PDF tool as soon as you start choosing files. After that, you can turn off your connection and still merge and edit pages.

Can I turn, move or remove pages after merging?

Yes. Tick the pages you want, then use Rotate, Move to or Remove in the toolbar above them. You can also drag pages on a computer, press Alt with an arrow key, or open a page larger to zoom in, crop away margins or change it there. Cropping keeps text sharp and selectable. Page size makes every page A4 or Letter. Select Apply changes, then download the updated file. Undo changes puts everything back.

What happens to my files when I leave the page?

They're cleared. Your files are only held in this browser tab, so starting over, closing the tab or leaving the page removes them, and pressing Back won't bring them back. If you haven't downloaded your result yet, your browser asks before you leave.

Can I merge password-protected PDFs?

Not yet. They're marked Has a password as soon as you add them. Remove the password in the app that created the file, then merge it here.

Will bookmarks, links and form fields be kept?

Pages, text and images are kept exactly, and turning a page keeps its full quality. Bookmarks, and some links and form fields, may not carry over into the merged file.
