Merge PDF files

Combine two or more PDFs into a single document. Put them in the order you want, then download the result — with no watermark and no cap on how many pages you combine.

How to merge PDFs

  1. Choose the PDF files you want to combine.
  2. Reorder them with the arrows until the sequence is right.
  3. Select Merge and download.

Questions

Does the order matter? Yes — pages appear in the order the files are listed. Drag them into place before merging.

Is there a file-size limit? No fixed cap. Very large documents simply take longer, and go faster on a desktop machine.

Can I merge password-protected PDFs? Not yet — remove the password first. The tool will tell you if a file is protected rather than failing silently.
