This article was previously published under Q140559 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.
