Personally, I think this method is better because it can save the animation. You can use iSpring to convert PPT into flash file.

Method 2: Convert PPT into video format.

This method is also good. At present, there are many softwares that can provide this video interception function, such as CamStudio and Jing. Or you can directly install PPT20 10 version of the software and save it in wmv format, and you can convert PPT into video. You can also upload PPT to a series of video websites such as Youku in this way.

Method 3: Convert PPT into PDF file.

This method is the most commonly used and relatively easy. There are many softwares for converting PDF files on the Internet, such as Adobe Acrobat pro, PDF995 and online PDF conversion tools.

Method 4: Encrypt PPT file.

This method may be tough, so it is called tough because it almost deprives others of the right to browse. Hehe, only people authorized by you can browse. In the version of PowerPoint2007 above 2007, you can choose "Office-Prepare-Encrypt Document" to realize encryption.

Method 5: Add digital signature to PPT file.

This method is very interesting. Just give it a try in Office 2007. It is similar to the original file, but it cannot be modified. But it is also possible to really modify it, so I won't say this. In Powerpoint2007, you can choose "Office-Prepare-Add Digital Signature" to realize confidentiality.

All right, choose a secret passage you like.
