Is there an easy way to "launder" a PDF file so that it won't appear to have been generated from LaTeX?
(I have a good reason for wanting to do this: I just tried to post an article to the arXiv, but the arXiv software isn't processing my latex source correctly, so I have to circumvent the usual way the arXiv creates a PDF from a source file. I plan to give the arXiv the source file too; I just don't want to get into a long argument with any humans about what I'm doing and why.)
I know this is more of a stackexchange sort of question, but I couldn't find it addressed there, and it strikes me as the sort of issue that mathematicians may face more often than others.
