Hi Team,

I am using Aspose.PDF API for .Net and trying to convert single page .tiff files to .pdf files. While doing so, the size the converted pdf file is getting increased a lot. I need help here.

Thank you for contacting support.

Would you please share narrowed down code snippet along with source and generated files so that we may try to reproduce and investigate further. Before sharing requested data, please ensure using Aspose.PDF for .NET 19.5.

Hi Farhan,

Thank you for replying back.

We have purchased the license for using Aspose.Pdf V19.5 and have been using it efficiently.

Below is the code that I am using for converting tiff to pdf. The output pdf file is lot more larger in filesize than the tiff file. Please help me here, as we have a plan to convert thousands of single paged tiff files to pdf and filesize is a concern.

                    Aspose.Pdf.Document doc = new Document();
                    // add blank page to pages collection of Document instance
                    doc.Pages.Add();
                    doc.PageInfo.IsLandscape = false;
                    // create Image object
                    Aspose.Pdf.Image image = new Aspose.Pdf.Image();


                    image.File = sourceFile;
                    // add image to paragraphs collection of PDF page
                    doc.Pages[1].Paragraphs.Add(image);
                    // save the file to the destination location, inside the folder (named as docid value)
                    doc.Save(destinationPDFfile);

The size of generated PDF document generally decreases when IsBlackWhite property of Image class is set to true. However, the program execution does not finish with your image file. Therefore, a ticket with ID PDFNET-46431 has been logged in our issue management system for further investigation and resolution. The ticket ID has been linked with this thread so that you will receive notification as soon as the ticket is resolved.

We are sorry for the inconvenience.

We have an active license for Aspose.Total, shouldn’t we get support by default?
Do we need to log a post while logging in from the corporate account that we have for Aspose?

You should set the IsBlackWhite parameter for the readed image to true.

var doc = new Document();            
doc.Pages.Add();
doc.PageInfo.IsLandscape = false;

var image = new Aspose.Pdf.Image();

image.File = dataDir + "46431.tiff";
image.IsBlackWhite = true;  // <------------  This line added.

doc.Pages[1].Paragraphs.Add(image);            
doc.Save(GetOutputPath("46431_out.pdf"));
