The answer depends on the input and the desired output. There are few ways to do that, like resize the file dimensions, convert the PDF file to text and drop any images, convert the images inside the PDF file to black and white, etc…

Using LEADTOOLS can reduce the size by manipulating the PDF file properties. And the code is as simple as this:
string sourceFileName = @"C:\Users\Public\Documents\LEADTOOLS Images\Leadtools.pdf";
string destinationFileName = @"C:\Users\Public\Documents\LEADTOOLS Images\LEAD_OptimizerOptions.pdf";
PDFFile pdfFile = new PDFFile(sourceFileName);
PDFOptimizerOptions myOptimizerOptions = new PDFOptimizerOptions();
myOptimizerOptions.AutoOptimizerMode = PDFAutoOptimizerMode.BestSize;
myOptimizerOptions.ColorImageDownsamplingMode = PDFDownsamplingMode.Average;
myOptimizerOptions.GrayImageDownsamplingMode = PDFDownsamplingMode.Bicubic;
myOptimizerOptions.MonoImageDownsamplingMode = PDFDownsamplingMode.Bicubic;
myOptimizerOptions.ColorImageDownsampleFactor = 2.0;
myOptimizerOptions.GrayImageDownsampleFactor = 2.0;
myOptimizerOptions.MonoImageDownsampleFactor = 2.0;
myOptimizerOptions.ColorImageDPI = 150;
myOptimizerOptions.GrayImageDPI = 150;
myOptimizerOptions.MonoImageDPI = 150;
myOptimizerOptions.ColorImageCompression = RasterImageFormat.Jpeg;
myOptimizerOptions.GrayImageCompression = RasterImageFormat.RasPdfLzw;
myOptimizerOptions.MonoImageCompression = RasterImageFormat.Jbig;
myOptimizerOptions.EmbedAllFonts = false;
myOptimizerOptions.SubsetFonts = true;
pdfFile.OptimizerOptions = myOptimizerOptions;
pdfFile.Convert(1, -1, destinationFileName);
