QPDF is a program that can be used to linearize (web-optimize),
|
|
encrypt (password-protect), decrypt, and inspect PDF files from the
|
|
command-line. It does these and other structural, content-preserving
|
|
transformations on PDF files, reading a PDF file as input and
|
|
creating a new one as output. 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 understands PDF files that use compressed object streams
|
|
(supported by newer PDF applications) and can convert such files into
|
|
those that can be read with older viewers. It can also be used for
|
|
checking PDF files for structural errors, inspecting stream contents,
|
|
or extracting objects from PDF files. QPDF is not PDF content
|
|
creation or viewing software -- it does not have the capability to
|
|
create PDF files from scratch or to display PDF files.
