Save PowerPoint Slides as 300 DPI High Resolution Image Files

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.

Microsoft Office 2007 and 2003

To enable the high-resolution feature, an optional registry parameter needs to be added into the Windows operating system registry. This is documented at Microsoft support website (http://support.microsoft.com/kb/827745). The optional registry parameter only works for Office 2007 (with Service Pack 2 installed) and Office 2003.

If you are running Office 2007, you need to make sure that Office 2007 Service Pack 2 is installed. The followings show you how to find the Office 2007 Service Pack level on your computer.

Open Microsoft PowerPoint 2007, click the Office Button at the upper left corner, and then click PowerPoint Options,

Click the Resources button

In the about Microsoft Office PowerPoint 2007, SP2 (red line below) means that your computer is running Office 2007 with Service Pack 2 already. You can proceed the next step “Adding the registry settings”. If you do not see SP2, you are required to install Office 2007 Service Pack 2. Please follow the link from Microsoft to download and install Office 2007 Service Pack 2.
