The qpdf program is used to convert one PDF file to another equivalent PDF file. It is capable of performing a variety of transformations such as linearization (also known as web optimization or fast web viewing), encryption, and decryption of PDF files. It also has many options for inspecting or checking PDF files, some of which are useful primarily to PDF developers.

For a summary of qpdf’s options, please run qpdf --help. A complete manual can be found in /usr/share/doc/qpdf/qpdf-manual.html or /usr/share/doc/qpdf/qpdf-manual.pdf.
