PDF files larger than necessary


Using Syncfusion.Pdf.Base v.10.403.0.71

After I produce a Syncfusion PDF file, I open it in Adobe PDF Reader. If I print it to a PDF Print Driver, it is significantly smaller in file size and seemingly the same quality/size.

Here are the Syncfusion PdfDocument properties that I set:


Private Syncfusion.Pdf.PdfDocument doc = new Syncfusion.Pdf.PdfDocument(PdfConformanceLevel.Pdf_A1B);

doc.FileStructure.CorssReferenceType = PdfCrossReferenceType.CrossReferenceStream;

doc.ColorSpace = PdfColorSpace.GrayScale;

doc.Form.Flatten = true;

doc.EnableMemoryOptimization = true;

doc.Compression = PdfCompressionLevel.Best;

I've tried every combination of CompressionLevel with no change. I've tried with and without Conformance with a very small change. I've tried with and without ColorSpace with no change. I've tried EnableMemoryOptimization on and off with no change.

Please help. I have to produce millions of PDF's and space is not plentiful.

Hi John,

Thank you for your interest in Syncfusion products.

The size of the PDF document is based on the elements it contains like text, image etc. Could you please send us a sample document so that we can check the elements and get back to you with details?

The simplest is to re-save your file as a reduced-size PDF. In the latest version of Adobe Acrobat, open the PDF you wish to re-save as a smaller file, choose File, Save as Other, and then Reduced Size PDF.
