Here are some simple instructions on how to combine multiple PDFs into a single PDF using Adobe Acrobat DC.
Please note, it’s quick and easy to combine multiple PDFs (and images) into a single proof in PageProof by following these instructions. When reviewers download the original proof file, they will download a zip file containing the PDFs used to combine together to make the proof.
However, if you want to combine several PDF files into a single PDF first so that your reviewers download a single pdf file, you can use Adobe Acrobat, then use that file to create a proof.
To combine multiple PDFs into a single PDF using Acrobat
Open Acrobat Pro DC and click Tools (found on the upper left corner of the app).
Click Create PDF.
Select Multiple Files and click Next. You can now drag and drop the PDF files that you want to combine together onto the dashboard.
Click Combine to create a single PDF file. Then you can download the new file you’ve just created.
