Edit PDF metadata
Read and rewrite the title, author, subject and keywords a PDF carries — or empty them all.

Every PDF carries a small dictionary about itself, and most people never look at it until it embarrasses them: a document titled "Untitled 3", an author field naming whoever owned the laptop the template came from, a producer string advertising the software that made it. Search engines read the title, some readers show it in the window bar instead of the filename, and anyone who opens the properties dialog sees the rest.
The fields are read out of the file when you drop it in, so you are editing what is actually there rather than filling in a blank form. Clear all empties every one of them at once, which is the common case for a document about to be sent outside the company.
The document itself is untouched. It is loaded and saved rather than rebuilt page by page, so the outline, the links, the annotations and the form fields all survive an edit that should never have gone near them — which is not true of tools that put the pages through a merge to change a title.

Questions
Does this remove everything identifying?
It clears the document information dictionary. It does not touch metadata embedded inside images, nor anything written into the page content itself.
What is the producer field?
The software that wrote the file, filled in automatically. It is the field most likely to say something you did not intend to publish.
Are the pages changed at all?
No. The file is loaded and saved with a different information dictionary; the pages, links and form fields are the ones that went in.
