Is there any limitation on the number of slides in a PowerPoint presentation that can be published by iSpring?

Yes, there is a limitation of Flash technology and it only influences very large presentations. We tested the conversion of different presentations including more than 500 slide long presentations and iSpring products showed quite stable results. Problems with conversion of large presentations might be caused by:
  • insufficient resources of your PC because the conversion process requires a high amount of RAM. To fix the problem, please increase the virtual memory on your PC.
  • the limitation on the number of frames set for Flash. Any Flash file can contain no more than 65536 objects. This limitation was set by the creators of Flash format and you may read more about it here.
