    pdftk A=1.pdf B=2.pdf cat A B output 12.pdf 
  • or (Using Wildcards):

    pdftk *.pdf cat output combined.pdf 
  • Split Select Pages from Multiple PDFs into a New Document:

    pdftk A=one.pdf B=two.pdf cat A1-7 B1-5 A8 output combined.pdf

    pdftk in.pdf cat 1E 2-end output out.pdf 
  • Rotate an Entire PDF Document’s Pages to 180 Degrees:

    pdftk in.pdf cat 1-endS output out.pdf 
  • Encrypt a PDF using 128-Bit Strength (the Default) and Withhold All Permissions (the Default):
