How to change the export resolution of a PowerPoint slide

Important Follow the steps in this section carefully. Serious problems might occur if you modify the registry incorrectly. Before you modify it, back up the registry for restoration in case problems occur.

By default, the export resolution of a PowerPoint slide that you want to save as a picture is 96 dots per inch (dpi). To change the export resolution, follow these steps:
1.    Exit all Windows-based programs.

2.    Click Start, and then click Run.

3.    In the Open box, type regedit, and then click OK.

4.    Locate one of the following registry subkeys, depending on the version of PowerPoint that you're using:

PowerPoint 2013
HKEY_CURRENT_USER\Software\Microsoft\Office\15.0\PowerPoint\Options
PowerPoint 2010
HKEY_CURRENT_USER\Software\Microsoft\Office\14.0\PowerPoint\Options
PowerPoint 2007
HKEY_CURRENT_USER\Software\Microsoft\Office\12.0\PowerPoint\Options
PowerPoint 2003
HKEY_CURRENT_USER\Software\Microsoft\Office\11.0\PowerPoint\Options

5.    Click the Options subkey, point to New on the Edit menu, and then click DWORD Value.

6.    Type ExportBitmapResolution, and then press Enter.

7.    Make sure that ExportBitmapResolution is selected, and then click Modify on the Edit menu.

8.    In the Edit DWORD Value dialog box, click Decimal.

9.    In the Value data box, type the value of the resolution that you want such as 300. Or, use the parameters in the following table.

 

10  Click OK.

11  On the File menu, click Exit to exit Registry Editor.

Step 2: Export the slide as a picture
1.    In PowerPoint, open your slide presentation, and then open the slide that you want to export.
2.    On the File menu, click Save As.
3.    In the Save as type box, select one of the following picture formats:
o    GIF Graphics Interchange Format (.gif)
o    JPEG File Interchange Format (*.jpg)
o    PNG Portable Network Graphics Format (*.png)
o    TIFF Tag Image File Format (*.tif)
o    Device Independent Bitmap (*.bmp)
o    Windows Metafile (*.wmf)
o    Enhanced Windows Metafile (*.emf)


Note You may want to change the picture's save location in the Save in box. You may also want to change the name of the picture in the File name box.

4.    Click Save. You are prompted with the following dialog box:

Click Current Slide Only. The slide is saved in the new format and resolution, in the location that you specified in the Save in box.

5.    To verify that the slide is saved in the resolution that you specified, right-click the picture, and then click Properties.

Limitations
When you set the ExportBitmapResolution registry value in PowerPoint, there's a limitation to consider. The maximum resolution that PowerPoint can export is 3072 pixels, based on the longest edge of the slide.
