Use two simple commands to convert a protected pdf into an unprotected pdf.

Here in this example i assume the protected pdf file name to be ‘protected.pdf’.

Now open your terminal and type.

$ pdftops protected.pdf out.ps
$ pstopdf out.ps out.pdf

The out.pdf will be your unprotected PDF.

If you don’t have pstopdf and pdftops installed then type this at terminal to install them.
