Below is a full working C# 2010 WinForms app targeting iTextSharp 126.96.36.199. It takes an existing JPEG on your desktop called LargeImage.jpg and creates a new PDF from it. Then it opens the PDF, extracts the image, physically shrinks it to 90% of the original size, applies 85% JPEG compression and writes it back to the PDF ITextSharp compress images in PDF. iTextsharp - PDF file size after inserting image, this confirms that iTextSharp is doing a simple, nice, generic lossless compression. It seems that PDF requires the png to be transcoded to something else, jpeg, most probably The rest is actual image compression inside the PDF. In this aspect iTextSharp will not make any noticable compression, and you will need to actually use iTextSharp to manually access each and every image stored as XObjects and extract them, recompress them, then overwrite the current XObject with the compressed image I used iTextSharp to create the PDF, and I'm pretty happy with the solution that I came up with. There were only two functions required: one that converts an image to a smaller size & lesser quality and one that combines the images into PDF. Here's the code: /// <summary>. /// Takes a collection of BMP files and converts them into a PDF. 1) The should be pdf Linearized. 2) The pdf should be compressed (PdfWriter.CompressionLevel = PdfStream.BEST_COMPRESSION) Inorder to really optimize your PDF, you really need to know the PDF format.
