Can this program keep all the originals of my PPT file, like preset timings, animations, video and audio, all transitions?

Generally, Leawo Products are capable of keeping all the PowerPoint originals, e.g., animations, transitions, video clips and sound tracks. In case your PPT file is rather complicated, and that causes loss of an effect, please report the error file to us via emailing to support#leawo.com(replace#with@).
