Disable PDF protection using two simple commands in Ubuntu

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.

sudo apt-get install context

This is not a usual thing here… Just a tool in case you need it.
