PDF-PPTX conversion

PDF can preserve the original appearance of the source file very well, so there are many uses and audiences. Recently, many customers have reported that they need to add the function of converting PDF files to PPTX files. Of course, Aspose.Pdf for .NET has fulfilled this function. To achieve this requirement, you only need to instantiate an object of the PptxSaveOptions class and pass it as the second parameter to the Document.Save(. .) method.
