We’re using Aspose Slide for .NET (C#) DLL version 21.2
Very simple comparison between original PPTX file (above) and generated PDF (below)

We have already tried increasing value of PdfOptions.SufficientResolution but to no avail, even if I set it to as high as 9600, quality is still same as if it was set to 128
@smljoju,
Thank you for contacting support.
To investigate this case on our side and assist you, please share and specify the following:
You can zip the files and upload them here.
This was tested in Win10, with following minimal sample code
Presentation presentation = new Presentation(input_file_full_path);
PdfOptions options = new PdfOptions();
options.JpegQuality = 100;
options.SufficientResolution = 128;
presentation.Save(output_file, SaveFormat.Pdf, options);
Attached are input/output files, it seems that issue actually only happens (or maybe only significantly noticeable) if image is rotated, see sample files below
