Last post Nov 12, AM by cparker Just because you tell iTextSharp to use compression when saving the PDF, it doesn't mean it will reduce it very much if at all. Until PDF 1. The difference is how the objects table is laid out and you can clean it up, that will only do so much though. The rest is actual image compression inside the PDF. A lot of people are against trying to do this yourself because any mishap and you corrupt the entire PDF file.
