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 a free service called SmallPDF, then use that file to create a proof.
Note: You can also do this using Adobe Acrobat by following these instructions.
To merge multiple PDFs into a single PDF using SmallPDF
Step 1
Step 2
Drag and drop the PDF files onto the drop area. Then click merge PDF.
Don’t forget to save and download your PDF file.
