For various kinds of reasons, these netizens expect that others can just view the PowerPoint files but cannot edit them, so they naturally hope to find a method to protect their PowerPoint files by encrypting PowerPoint files.
Actually, it is incredibly easy. On one hand, Microsoft Office PowerPoint itself has provided us with a method to encrypt our PowerPoint files. On the other hand, many PPT masters also concluded good ways to encrypt PowerPoint files. Today, I would like to introduce 3 methods to encrypt your PowerPoint file, and I will take Microsoft Office PowerPoint 2010 as an example, hope it is useful to you！
Method 1 Encrypt PowerPoint File by Password
Microsoft Office PowerPoint 2010 allows its users to encrypt their PowerPoint File by setting Passwords. Clicking “File” > “Save AS” to open a new dialog box. Click the “Tools” button in the lower left corner of the dialog box and choose “General Options” in the drop down menu. Immediately you can see another dialog box in which you are enabled to set Passwords for the PowerPoint file. “Password for open” is used to view the PowerPoint file and “Password for modify” is used to edit the PowerPoint file.
Method 2 Save the PowerPoint Files as PPS format
Another easy way is to save the PowerPoint files as PPS format. Click “File” > “Save AS” and set “Save as type” as PPS format.
Method 3 Save the PowerPoint Files as PDF format
This method is similar to the above one, you just Substitute PPS format with PDF format.
