@lpappachen I apologize for the inconvenience, but I was unable to reproduce the issue you mentioned. I successfully created the PDF file based on the presentation you provided.

I am currently using the latest version of the Aspose.Slides API (v23.5) and the following code:

Presentation presentation = new Presentation("C:\\Temp\\slides\\input.pptx");

var saveOpt = new Aspose.Slides.Export.PdfOptions() {
    EmbedFullFonts = true,
    EmbedTrueTypeFontsForASCII = true,
};

// Saves the presentation as a PDF
presentation.Save("C:\\Temp\\output.pdf", Aspose.Slides.Export.SaveFormat.Pdf, saveOpt);

If there are any specific steps or additional information you can provide to help replicate the problem, please let me know.

What could be the reason this issue happens? Even in our environment it changes ocasionally on what document causes the issue

@lpappachen that error can be challenging to solve. Please note that this specific exception is not an internal exception of the Aspose.Slides API. When GDI+ is unable to save files, it throws an error, which can be caused by various reasons such as a non-existent file path, file blocking, missing permissions, and so on. Could you please provide the stack trace of your exception so that we can investigate its origin?

The file that caused issue was PPT. You specified aspose.words api was that a typo?

@lpappachen yes, that was a typo. Sorry for the confusion, I’ll fix it.
