Merging pdf files

This post is about combining pdf files. It complements 2 earlier posts on splitting pdf files - part 1, and 2.

I am using a tool named SimpleScan to scan in multiples pages of a document. Each page is scanned into a separate pdf file. I must find a way to stitch the pdf files together into one single pdf.

You can use either the pdftk command, or the gs command to merge pdf files. You may recall that they are the same commands you would use to split pdf files. In the examples below, the input files are T4a.pdf, T4b.pdf, and T4c.pdf; the merged output file is combined.pdf.

  • pdftk
    $ pdftk T4a.pdf T4b.pdf T4c.pdf output combined.pdf
    
  • gs (GhostScript)
    $ gs -sDEVICE=pdfwrite -dNOPAUSE -dBATCH -dSAFER -sOutputFile=combined.pdf T4a.pdf T4b.pdf T4c.pdf

P.S. You can also merge pdf files using ImageMagick. Refer to my post.
