How To Change Resolution On Powerpoint For Mac

Try to open the PowerPoint program in a low resolution; Your screen might be too large. In order to go to a lower resolution, do the following: Exit out of the PowerPoint program. Go to your Mac’s System Preferences. Choose on Displays Panel. Select the lowest resolution and check the box near it. I want to increase the target resolution when exporting slides as images in PowerPoint 2011 for Mac. In other forums it says to go to Preferences - Save, and from there you can change the dpi.

PowerPoint presentations are designed to fill a computer monitor screen. If your PowerPoint slides aren’t doing that, you may have inherited an old PowerPoint presentation with slides that need resizing. In that case, follow these steps to choose a new size for the slides in your presentation:

1Click the Design tab.

You have to be in the Design mode to make changes to your slide sizes.

2Click the Page Setup button.

The Page Setup dialog box opens.

3Click the down-arrow on the Slides Sized For drop-down list and choose an On-Screen Show setting.

You can choose 4:3, 16:9, or 16:10. These settings determine the width-to-height ratio of slides when they are displayed at full-screen size during a presentation. The commands in the Page Setup dialog box apply to all the slides in a presentation.

4Click OK.

Most of the options on the Slides Sized For drop-down list pertain to printing slides on paper.


You can change the export resolution in Microsoft PowerPoint by saving a slide in a picture format. There are two steps to this process: using the system registry to change the default resolution setting for exported slides, and then actually saving the slide as a picture at the new resolution.

Step 1: Change the export resolution setting


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. Right-click the Start button and then Run. (In Windows 7, select Start, and then Run.)

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

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

    PowerPoint 2016


    PowerPoint 2013


    PowerPoint 2010

    If it crashes anyways, you may be looking at a hardware problem. Rufus for mac dmg.


    PowerPoint 2007


    PowerPoint 2003


  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, select 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.

    Decimal valueFull-screen pixels (horizontal × vertical)Widescreen pixels (horizontal × vertical)Dots per inch (horizontal and vertical)
    50500 × 375667 × 37550 dpi
    96 (default)960 × 7201280 × 72096 dpi
    1001000 × 7501333 × 750100 dpi
    1501500 × 11252000 × 1125150 dpi
    2002000 × 15002667 × 1500200 dpi
    2502500 × 18753333 × 1875250 dpi
    3003000 × 22504000 × 2250300 dpi


    See the Limitations section for more information when you set this value.

  10. Select OK.

  11. On the File menu, select 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, select Save As.

    This spreadsheet has been used by hundreds of thousands of people and remains one of my most popular budgeting tools. However, many people may not realize that I have created a few other variations recently. It will show you how to get started, how to customize your budget categories, how to enter budget amounts for each month, and how to tell whether you are under or over budget each month. Both of these provide additional features that the basic planner does not have.If you are new to Excel or new to budgeting, or both, take a look at the video demo below.

  3. 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.

  1. Select Save. You will be prompted with 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.

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


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:maxdpi = (sqrt(100,000,000 / (slide with * slide height)), where slide width/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 only limited by how big the resulting bitmap gets. PowerPoint can support creating 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 1000. For the old style 10” x 7.5” slides this means a maximum of 1155 DPI, but depending on slide size, this can be more or less.

PowerPoint 2010 and older

The maximum resolution that PowerPoint can export is 3072 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 3070-pixel result (10 × 307 = 3070) falls within the 3072 limit. However, any DPI setting that's greater than 307 for a standard slide reverts to the limit of 3072.

Decimal valuePixels (horizontal × vertical)Dots per inch (horizontal and vertical)
3073072 × 2304307 dpi

The 3072-pixel limit also applies to saving the slide programmatically.

For example, the following code programmatically saves a picture with dimensions of 3072 × 2304 pixels:
