  1. Settings

    Choose a conversion engine first. The default conversion engine is compiled from open-source codes. The exclusive conversion engine is designed by our software team. It differs from conversion engine created by other companies. The exclusive engine is much slower but may have better results. The third conversion engine uses the official Microsoft Office PowerPoint software to perform conversion. When your PowerPoint file is uploaded, Microsoft PowerPoint software will be launched to open your PowerPoint file and save it as PDF file. Try all three conversion engines if you are not sure which one is more suitable for your task. You can close "Settings" section by clicking the "X" on the right if you use default settings.

The big change in PowerPoint 2007 was that the stable binary file format of 97-2003 (.ppt files) was replaced as the default by a new zipped XML-based Office Open XML format (.pptx files). Microsoft's explanation of the benefits of the change included: smaller file sizes, up to 75% smaller than comparable binary documents; security, through being able to identify and exclude executable macros and personal data; less chance to be corrupted than binary formats; and easier interoperability for exchanging data among Microsoft and other business applications, all while maintaining backward compatibility. Here are main presentation formats supported:

Microsoft Office PowerPoint presentation format.
Old Microsoft PowerPoint 97-2003 binary presentation.
Microsoft PowerPoint slide show format.
As Microsoft Office PowerPoint, but with macro support. The replacement for .PPT format.
The Open Document Format for Office Applications (ODF).
