PDF compression- We have PDF which contains more than 500 pages, it contains table, Images (Banners) and other symbols . now expectation here is to reduce the PDF size without compromising the quality. current PDF size is around 2 GB, expected is 200-500 MB.

What I have tried:

i tried with iTextsharp and Ghostscript 1) created PDF and tried compress 2) splitted PDF pages into png and tried to club it. no use. either quality is getting reduced or size is not reduced .

You will never compress 2GB of PDF into 500MB. PDFs do not lend themselves well to compression because they are already structured in a fairly efficient manner.

No, the magic you are looking for, simply does not exist.
PDF is already compressed, the only way to get further compression, is to reduce quality.
