Reduce PDF file size in C#

Hello, I can manually (by clicking File -> Save as -> Reduced Size PDF) reduce a pdf size from 86M to 3.5M. I need to reduce size using Aspose.PDF (version 9.0) in C#. How can I do that?

I tried to use pdfDocument.OptimizeResources(), but it only reduced size from 86M to 84M. that is not enough. Please help.

Hi Alea,


Thanks for contacting support.

Can you please share the resource file so that we can test the scenario at our end. As the file size it too large, so you may upload it to some free FTP and share the link. We are sorry for this inconvenience.
