How to merge PDF files

  1. Click Select PDF files and choose two or more PDFs, or drop them on the page.
  2. Drag the files into the order you want, or sort them A–Z.
  3. Click Merge PDF and download the combined file.

Merging is useful for putting an application together, combining scanned pages, or sending one file instead of many.

Private by design

Merge PDF runs entirely in your browser. Your file is processed on your own device and is never uploaded, so it stays private. It’s free, with no sign-up and no watermark.

Frequently asked questions

How many PDFs can I merge?

As many as your device can hold in memory. Dozens of files at once is normal.

Will the pages keep their quality?

Yes. Pages are copied as they are, so text stays sharp and selectable.

Can I merge password-protected PDFs?

Yes, if you know the password. You’ll be asked for it when you add the file, and the merged PDF won’t have a password.
