how are scribbles saved when you write on a PDf? a file per page?
might be possible to find an open source PDF editor, add code to insert scribbles inside PDF itself
Separate binary files (called "1", "2", "3" etc.), one per page of the PDF that you've scribbled on, inside a folder named after the PDF. It should be quite easy to translate the current format into another vector (or even raster) format, then use one of the free tools such as jpdftweak to stamp the results into the source PDF (all on a desktop PC of course).
