You can also change the density (pixels per inch) of the images saved. Keep in mind that this option will only be set for the current presentation, which means you have to do this over again when you work on another presentation.

  • To enable this for all the presentations you make, you need to turn to the Registry (back up your Registry before proceeding). Start the Registry Editor.
  • Navigate to HKEY_CURRENT_USER\Software\Microsoft\Office\12.0\PowerPoint\Options.
  • Create a new DWORD here. Call it AutomaticPictureCompressionDefault. The default value will be 0.
  • This disables the automatic compression of pictures. If at anytime you want it enabled, double-click the DWORD and change its value to 1.
