Export high resolution images from PowerPoint
PowerPoint makes it easy to produce professional looking graphics quickly. Sometimes I need to export high quality versions of those slides. By default, PowerPoint limits exports to a resolution of 96 DPI (by comparison, many printers use 300 DPI). However, it is possible to change the default DPI by creating a registry entry.
For Office 2007, browser to
HKEY_CURRENT_USERSoftwareMicrosoftOffice12.0PowerPointOptions
And create a new DWORD value called ExportBitmapResolution
. Finally set the value to the DPI you want, e.g., 300
.
Now you can export high quality slides by saving them as images.
Instructions for Office 2003 and a list of DPI values and their corresponding image sizes is available at http://support.microsoft.com/kb/827745
