Free version of the program that allows you to convert Microsoft PowerPoint presentations into SWF files (Macromedia Flash), which can be later published, for example, on a website. iSpring Free fully integrates with PowerPoint and all its options are available from the PowerPoint menu. Support for the program is almost banal - after clicking on the Publish button, a small window appears with the default settings and the proposed location of the resulting file, and another click on Publish generates the file.

In the free version it is possible to set the dimensions of the animation, determine from which part of the presentation the animation is to be generated, as well as the intervals after which subsequent slides are to be displayed.
