Sometimes we thought iPhone as a mini PC, but I notice that when some one want to view their PowerPoint (maybe for business speech, maybe for review the courseware) on iPhone, it is very inconvenient. Most people have to save their PowerPoint files to pictures and then view those pictures on the iPhone. Now I’d like to tell people how to make it work.

The quick and inexpensive way to view your PowerPoint on iPhone is using PPT to video. PPT to video is an app which can join iPhone and PowerPoint together. Below are the details about how to put your PowerPoint file on iPhone.
1.Download the program PPT to video, For most users, the free version is enough. Then install it on your computer.
2.Run the program, and import the PPT file, then start to convert it to MP4 format, PPT to Video can convert PowerPoint to MPEG, AVI, MP4, MOV and 3GP with excellent quality. And with this tool, you can view your PowerPoint on PSP, iPod, pocket PC, and blackberry. You can also upload your PowerPoint to YouTube.
3.Put the converted file to your iPhone, all things are OK!
Then the second way is convert your PowerPoint to PDF format and then open your PDF file on iPhone with PDF viewer or Safari. Compared to the method above, it cannot remain the animations and sounds from your computer.
1.Download the PowerPoint to PDF converter and install in on your computer.
2.Convert your PowerPoint into PDF format then put it in your iPhone.

There are, of course, many other ways to do this, I was just talking about something very quick and inexpensive that would get the job down.
