You may have known already that most of publishers do not accept PowerPoint slides as figures. By default, when you save a PowerPoint slide as an image file, the resolution is 96 DPI. However publishers require 300 DPI or higher for figures. It will be very time consuming to recreate figures by using other graphic software, e.g., Adobe PhotoShop.

This paper shows you step-by-step how to save PowerPoint slides as 300 DPI high resolution images (.jpg, .tiff, et al) directly from PowerPoint.

To enable the high-resolution feature, an optional registry parameter needs to be added into the Windows operating system registry (regedit.exe).

Special note

By changing registry setting allows you to save a PPT slide to an image with 300 DPI resolution, however there is no guarantee if the resolution of originally embedded images in PPT slides is less than 300 DPI. In other words, you CANNOT bump up the image resolution from low to high.

However you will be guaranteed your saved images from PowerPoint have true 300 DPI if the embedded images in PPT slides are vector graphics.
