Hi Mike,


Thanks for contacting support.

One way of compression the PDF file size is to compress the images (change their type) within the PDF document. Please try using the following code snippet to accomplish your requirement.

[C#]

Document pdfDocument = new Aspose.Pdf.Document(“c:/pdftest/Memory+Test.pdf”);<o:p></o:p>

foreach (Page page in pdfDocument.Pages)

{

int idx = 1;

foreach (Aspose.Pdf.XImage image in page.Resources.Images)

{

using (var imageStream = new MemoryStream())

{

image.Save(imageStream, System.Drawing.Imaging.ImageFormat.Png);

imageStream.Seek(0, SeekOrigin.Begin);

page.Resources.Images.Replace(idx, imageStream);

}

idx = idx + 1;

}

}

pdfDocument.Save(“c:/pdftest/Compressed_output.pdf”);
