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
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:
Step 2: Export the slide as a picture
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.
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: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.
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:
More information
For information about changing the size of your slides, see Change the size of your slides.
Dots per inch or 'dpi' is a measurement of the quality of an image. Typically, the higher the dpi, the better the quality of the image. A high-quality image is important for printing posters or other large format images or graphics. Adobe Acrobat Professional files are called Portable Digital Format or 'pdf,' a high-quality digital file suitable for use in commercial offset printing. Converting your PowerPoint slide to a .pdf will make it acceptable for high-quality, larger format printing.
Step 1
Open the slide presentation in Microsoft PowerPoint. Click 'Print.'
Step 2
Click the drop-down menu arrow next to 'Name' in the print pop-up window menu. Select 'Adobe PDF,' as your printer. Click the 'Properties' button located right next to the printer name drop-down menu.
Step 3
Select the 'Adobe PDF Settings' tab. Place a check mark in the 'View Adobe PDF Results' box to allow Adobe Reader or Professional to open your .pdf file for viewing.
Step 4
Select the 'Layout' tab and click the 'Advanced' button. This will open up the 'Adobe PDF Converter Advanced Document Settings' pop-up menu. Click the 'Plus Sign' next to the 'Graphic' menu option to expand the graphic options.
Step 5
Click the 'dpi' setting next to 'Print Quality,' in the graphic options, to change the dpi. A drop-down menu should appear to allow you to change the dpi settings. Select '300 dpi' from the menu. Click 'OK' to close the options pop-up window. Next click 'OK' to close the 'Adobe Document Properties' pop-up window.
Click 'OK' once more to close the 'Print' pop-up window and open the 'Save As' window. Name your file in the 'File Name' dialog box and be sure to check that the 'Save As' type is set to pdf. Select the location to save the pdf file. Click Save to create your pdf. Once the conversion is complete, your pdf will open in your Adobe Acrobat program.
