Let’s say we want to merge three pdf files head.pdf, body.pdf, and foot.pdf into one file named all.pdf. Using pdfunite we can effortlessly merge all those pdf files like so

pdfunite head.pdf body.pdf foot.pdf all.pdf

And that’s literally the only thing we need to do to merge all those pdf files into one single file, the order of the merged file would follow the order in the source file, so the above command will resulted a pdf file with the following order head.pdf, body.pdf, foot.pdf.

Stay safe!
