About the tool

What is Merge PDF?

Merging is the quickest way to turn a pile of separate documents into one file you can send, print or archive: a cover letter plus a CV, ten scanned invoices, or chapters of a report written by different people. The pages are copied exactly as they are, so fonts, images and layout stay the same.

Files are joined from top to bottom, so check the order before you press the button. If you spot a mistake afterwards, open the result in Organize PDF to move single pages around, or use Compress PDF if the final file is too large to email.

Your files stay with you. This tool works inside your browser tab. Nothing you select is uploaded, stored or seen by us.

How to use Merge PDF in 3 steps

  2. Drag the files into the order you want, or use the arrows
  3. Click Merge and download the combined file

💡 Pro tips

  • Name your files 01, 02, 03 before uploading, then they usually arrive in the right order.
  • Merge first, then compress. One compressed file is easier to send than several.
  • Add page numbers after merging so they run through the whole document.

FAQ

Frequently asked questions

How many PDFs can I merge at once?

There is no fixed limit. The practical limit is your device's memory, because everything is processed in your browser. Dozens of normal files merge without trouble on a modern computer.

Will the quality change when I merge?

No. Pages are copied without re-compressing text or images, so the merged file looks identical to the originals.

Can I merge password-protected PDFs?

Not directly. Remove the password in the program that created the file first, then merge it.

Are my files uploaded anywhere?

No. The merge happens on your device inside the browser. Your documents are never sent to a server.
