Hello,
Thanks for your patience.
Regarding the issue SPIREPPT-1505, you installed our Spire.Presentation via NuGet, right? If so, kindly note that install our product via NuGet, your project will use the .NETStandard dlls by default, which will take a long time to convert the PPT file to PDF. After further investigation, we found that this is due to the limitations of the .NETStandard library itself and it is difficult to optimize.
However, when using our .NETCore dlls, the conversion speed will be greatly improved. Therefore, we suggest you install Spire.Office.NETCore package to use the .NET core dlls of our Spire.Presentation.
If there is any question, please feel free to write back.
Sincerely,
Brian
