Hi Yuan,

I have observed your comments and like to share with you that the error appears while cloning the slides. For conversion, cloning is not required. Please try using below code on your end to serve the purpose. I have attached the generated html file for your kind reference (see 50个经典培训故事_16.3.0.rar).

Presentation pres = new Presentation(@"D:\50个经典培训故事.ppt");
pres.Save(@"D:\50个经典培训故事_16.3.0.html", SaveFormat.Html);

I hope this will be helpful. Please share if I may help you further in this regard.

Best Regards,

Hi：

Thank you for your reply,but I really need to convert each ppt page into another html.Because if the page of ppt has so many pictures,it is too slow when websites render page with the whole resource(files).

I have hoped that it can work more efficient when we use paging processing method.

By the way,Do the “Aspose.Slides” provide the service like paging processing? Or is there any way that you have to solve my issue（the results of html with too many files，the websites sender page too slowly and it need more resource of computer）

Once again, thank you for your help, I would appreciate if you have good news for me as soon as possible

Best Wishes!
