PDF Decrypter Command Line

You may protect your PDF documents with user password that anybody who does not know the user password cannot open the PDF file. However, there always are some protected PDF files having expired the protection period, and needing to be published without any restriction. Now you must need the tool PDF Decrypter Command Line that is excellent in removing user password of PDF.

The commands to remove a known user password of a PDF are in the following command line.

pdftoolbox protected.pdf -inputpassword UPWDTORM -outfile unprot.pdf

With the command line, program pdftoolbox uses the open password UPWDTORM to open the input PDF file protected.pdf and then saves a new PDF as unprot.pdf without user password. The option -inputpassword indicates the user password following it, and -outfile specifies the name to save the new PDF file. Now the newly saved PDF unprot.pdf is no longer protected by the user password, and anyone can open the PDF without inputting the user password.
