QUESTION: What is a linearized PDF file?
ANSWER: A linearized PDF file is a
PDF file that
is structured in a way that allows the first page of the
PDF file to be displayed in a user?s Web browser before
the entire file is downloaded from the Web server. If
you're developing a Web-based system that creates large PDF
files for delivery to Web browsers over the Internet, you should try to
make sure that your system can generate linearized PDF files.
Your users might become frustrated and impatient if your system
creates large PDF files that are not linearized, because it
could take 30 seconds or even longer for a user?s Web browser
to display a large PDF file that is not linearized.
In this context, when we talk about "large" PDF
files, we're referring to PDF files that have lots of text
and graphics and contain more than one page.
If your PDF files will be small and relatively simple, you
probably don?t need to worry about linearization.
Note that there is no reason to concern yourself with
linearization unless you're creating a Web-based system that
is intended to display PDF files in a user's Web browser. For
example, if you are creating a system that emails PDF files
to recipients, there is no reason to linearize the PDF files.
