You can try LEADTOOLS Document SDK. With LEADTOOLS you can load, view, save, convert, and compress PDF files. Using the PDFOptimizerOptions Class and the Optimize Method you can efficiently reduce the size of PDF files while preserving as much of the original file's quality as possible. The code is as simple as this: using (RasterCodecs codecs = new RasterCodecs()) { string sourceFile = @"C:\Temp\1.pdf"; var info = codecs.GetInformation(sourceFile, true); pdfFile = new PDFFile(sourceFile); var currentOptions = new PDFOptimizerOptions(); currentOptions.AutoOptimizerMode = PDFAutoOptimizerMode.BestSize; pdfFile.OptimizerOptions = currentOptions; string exportFile = @"C:\Temp\OptimizedPDF.pdf"; pdfFile.Optimize(exportFile); } For more information, see the following links: https://www.leadtools.com/help/leadtools/v20/dh/pdf/pdffile.html https://www.leadtools.com/help/leadtools/v20/dh/pdf/pdfoptimizeroptions.html https://www.leadtools.com/help/leadtools/v20/dh/pdf/pdffile-optimize.html You can also find a forums post including a sample project, written in C#, to compress and optimize PDF file at the following link: https://www.leadtools.com/support/forum/posts/t12408-
