QPDF application package that enables developers to easily view, analyze and modify the structure of PDFs

Always useful to have options, webfork previously mentioned it - quoted below

Application package that enables developers to easily view, analyze and modify the structure of a PDF file such as merge, split, overlay/underlay, rotate etc. QPDF is also capable of creating linearized (also known as web-optimized) files and encrypted files.

Another PDF editor: QPDF

In particular, this program does a lot of things but I've had difficulty finding a freeware program that protects PDF documents with good encryption (everything uses old, weak RC4), there's a command-line tool with batch operations that you can use.

The program does an amazing array of other interesting things to do with PDF, including compression and merging, but also something I hadn't heard of before: "Linearization" which is:
... a variant on the PDF file layout as described previously. Linearization is also called “Fast Web View”. Linearization shuffles the contents of the PDF file to place all of the information needed to display the first page near the beginning of the file.

I thought of myself as that person, but I don't mind being supplanted or replaced. :)

We can definitely use more than one PDF guy!

Or a death match, I dunno.
