You’ll need something custom, at leeast that’s how I solved it
I added an extra file field so people could upload the file, using hook_node_insert/hook_node_update I intercepted the upload, converted it, and store the result in the other file field.
You could do it using a custom file field widget as well, just extend the current one (have a look at the image field widget, it extends the file widget)

Subject: [development] File upload and convert
I have a content type with TWO file fields, in which I will designate TWO PDFs. On upload completion I want to run something like: "exec(pdftk f1.pdf background f2.pdf output f1.pdf)". This will "brand" f1.pdf.
I don't see any standard mechanism and so I'm not sure how to go about this. I have a general understanding, but that doesn't answer the question. I am sure I don't want to intercept all possible uploads; just the uploads from this specific content type. So, can I define a file upload hook which is scoped to this specific content type? I haven't seen anything that makes me believe I can. Can I create a custom file field to use any time I need to perform a conversion? Can my custom file field "extend" the existing file field, so I don't have to port improvements/bugfixes to my custom file field version?
So many questions... (-:
Thanks for the help,
