I need to remove some restrictions from a .pdf document:

enter image description here

I can't zoom or use any other buttons. The toolbar just isn't available. I never saw a .pdf file like this one.

    Point us to a PDF link if you want a remotely useful answer. – Mike Fitzpatrick Nov 14 '10 at 11:53
  • If the PDF is protected, there's very little you can do to unprotect it. –  Nov 14 '10 at 21:02
  • You can try this if the PDF has permission pswd => gswin64c -dSAFER -dBATCH -dNOPAUSE -sDEVICE=pdfwrite -sFONTPATH=%windir%/fonts;xfonts;. -sPDFPassword=123456 -dPDFSETTINGS=/prepress -dPassThroughJPEGImages=true -sOutputFile=OUTPUT.pdf INPUT.pdf – dns Nov 04 '15 at 13:23

You have two options:

  • with ghostscript:

    gs -q -dNOPAUSE -dBATCH -sDEVICE=pdfwrite -sOutputFile=%stdout% -c .setpdfwrite -f locked.pdf > unlocked.pdf

  • with pdf2ps and ps2pdf (slower):

    pdf2ps locked.pdf - | ps2pdf - unlocked.pdf

    If the unlocked PDF contains error, try to decompose the commands (ps2pdf have sometimes problems with a streamed input):

    pdf2ps locked.pdf unlocked.ps
ps2pdf unlocked.ps unlocked.pdf

  • Alternatively => gswin64c -dSAFER -dBATCH -dNOPAUSE -sDEVICE=pdfwrite -sFONTPATH=%windir%/fonts;xfonts;. -sPDFPassword=123456 -dPDFSETTINGS=/prepress -dPassThroughJPEGImages=true -sOutputFile=OUTPUT.pdf INPUT.pdf – dns Nov 04 '15 at 13:22
