SUMMARY
If you open and then save a PowerPoint presentation in Windows that was originally created on a Macintosh, you may notice that the file size increases significantly.



MORE INFORMATION
When you save a file in PowerPoint for the Macintosh and that file contains graphic images, the graphics are stored as native Macintosh graphic (QuickDraw) commands.

When you open the same file in PowerPoint for Windows, the file's size increases because the graphic images contained in the presentation are converted into Windows GDI (Graphics Device Interface) commands. If the graphics are bitmap-based, the GDI commands may require more disk space than the equivalent QuickDraw commands.

Likewise, if you open and save a file in PowerPoint for the Macintosh that was created in PowerPoint for Windows, the file size decreases.

The difference in file size may vary, depending on the number of graphics inserted into the presentation, the graphical resolution, and the number of colors.
