QPDF: A Content-Preserving PDF Transformation System
What is QPDF?
QPDF is a command-line program that does structural,
content-preserving transformations on PDF files. It could have
been called something like pdf-to-pdf. It also provides
many useful capabilities to developers of PDF-producing software or
for people who just want to look at the innards of a PDF file to
learn more about how they work.
QPDF is capable of creating linearized (also known as
web-optimized) files and encrypted files. It is also capable of
converting PDF files with object streams (also known as compressed
objects) to files with no compressed objects or to generate object
streams from files that don't have them (or even those that already
do). QPDF also supports a special mode designed to allow you to
edit the content of PDF files in a text editor. For more details,
please see the documentation links below.
QPDF is not a PDF content creation library, a PDF viewer, or
a program capable of converting PDF into other formats. In
particular, QPDF knows nothing about the semantics of PDF content
streams. If you are looking for something that can do that, you
should look elsewhere. However, once you have a valid PDF file,
QPDF can be used to transform that file in ways perhaps your
original PDF creation can't handle. For example, programs generate
simple PDF files but can't password-protect them, web-optimize
them, or perform other transformations of that type.
