How to merge PDF files into one PDF

When several PDFs belong together, merge them into one document instead of sending or uploading each file separately.

Quick answer

Select the PDFs in the order you want, then merge them into one file.

The merge tool copies the pages from each selected PDF into one new document. Keep the files in the intended order before you start.

Combine PDFs in a few steps

  1. Choose the PDF files.Select at least two documents that should become one file.
  2. Check the file order.The selected file order controls which document appears first, second and so on.
  3. Merge the documents.Run the tool and download the combined PDF.
  4. Check the result.Open the merged file and confirm the page sequence before sharing it.
Merging is not compression

Combining documents does not necessarily reduce file size. Compress the merged PDF separately if an upload limit is the problem.

The originals stay separate

The tool creates a new merged file rather than replacing the source PDFs.

Common questions

Can I merge more than two PDFs?

Yes. Select multiple PDFs and they are combined in the selected order.

Will merging change the page quality?

Pages are copied into the new PDF rather than rendered as images.

Can I compress the merged file afterward?

Yes. Use Compress PDF if the combined document is too large.
