You can change the export resolution in Microsoft PowerPoint by saving a slide in a picture format. There are two steps to this process: Use the system registry to change the default resolution setting for exported slides, and then save the slide as a picture at the new resolution.
Step 1: Change the export resolution setting
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:
Exit all Windows-based programs.
Right-click
Start
, and then select
Run
. (In Windows 7, select
Start
, and then select
Run
.)
In the
Open
box, type
regedit
, and then select
OK
.
Locate one of the following registry subkeys, depending on the version of PowerPoint that you're using:
PowerPoint 2016, 2019, PowerPoint for Microsoft 365
HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\PowerPoint\Options
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
Select the
Options
subkey, point to
New
on the
Edit
menu, and then select
DWORD (32-bit) Value
.
Enter
ExportBitmapResolution
, and then press Enter.
Make sure that
ExportBitmapResolution
is selected, and then select
Modify
on the
Edit
menu.
In the
Edit DWORD Value
dialog box, select
Decimal
.
In the
Value data
box, specify a resolution of
300
. Or, use the parameters from the following table.
Decimal value
Full-screen pixels (horizontal × vertical)
Widescreen pixels (horizontal × vertical)
Dots per inch (horizontal and vertical)
Step 2: Export the slide as a picture
In PowerPoint, open your slide presentation, and then open the slide that you want to export.
On the
File
menu, select
Save As
.
In the
Save as type
box, select one of the following picture formats:
GIF Graphics Interchange Format (.gif)
JPEG File Interchange Format (*.jpg)
PNG Portable Network Graphics Format (*.png)
TIFF Tag Image File Format (*.tif)
Device Independent Bitmap (*.bmp)
Windows Metafile (*.wmf)
Enhanced Windows Metafile (*.emf)
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.
Select
Save
. You will be prompted by the following dialog box:
Select
Current Slide Only
. The slide is saved in the new format and resolution in the location that you specified in the
Save in
box.
To verify that the slide is saved in the resolution that you specified, right-click the picture, and then select
Properties
.
Limitations
When you set the
ExportBitmapResolution
registry value in PowerPoint, there's a maximum DPI limitation to consider for some versions of PowerPoint.
Maximum DPI is dependent upon the slide size. The formula is as follows:
maxdpi = (sqrt(100,000,000 / (slide with * slide height)), where slide width and height are in inches.
For example, for a standard 13.3" x 7.5" slide, the equation would be:
sqrt(100,000,000 / (13.333 * 7.5) ) = 1000.
PowerPoint 2019, 2016, 2013, and 365
There is no fixed DPI limit. Slide export is limited only by how large the resulting bitmap gets. PowerPoint can support bitmaps up to 100,000,000 pixels (width x height). For standard widescreen slides (13.3" x 7.5"), this means a maximum DPI of 1,000. For the older style 10" x 7.5" slides, this typically means a maximum DPI of 1,155.
PowerPoint 2010 and older
The maximum resolution that PowerPoint can export is 3,072 pixels, based on the longest edge of the slide. For example, the standard 10" × 7.5" slide has a maximum effective DPI value of 307. The 3,070-pixel result (10 × 307 = 3070) falls within the 3,072-pixel limit. However, any DPI setting that's greater than 307 for a standard slide reverts to the limit of 3,072.
Decimal value
Pixels (horizontal × vertical)
Dots per inch (horizontal and vertical)
The 3,072-pixel limit also applies to saving the slide programmatically.
For example, the following code programmatically saves a picture that has the dimensions of 3072 × 2304 pixels:
ActiveWindow.Selection.SlideRange(1).export
"c:\<filename>.jpg","JPG",4000,3000
