Sometimes we need to export our PowerPoint slides as high-resolution images (JPEG or PNG format). This can be useful for when you are going to print slides, or upscale them for larger displays. The problem is that the default export resolution for images in PowerPoint is very low. To adjust this, you need to do some technical magic on your Windows PC. But it's very simple to get done, and you only need to do it once on your computer.

Here's how to change the export resolution setting

Step 1: Change the Export Resolution Setting

1. Close PowerPoint and other Windows-based programs

2. Right-click on the Start button and select "Run."

3. Type regedit in the Open box and click "OK."

   
   

4. Navigate to the PowerPoint registry subkey. Depending on your version of PowerPoint, locate the appropriate subkey. It will most probably be here:
   HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\PowerPoint\Options

5. Right-click on the Options subkey, select "New," then "DWORD (32-bit) Value." Name the new value ExportBitmapResolution and press Enter.

   
   

6. Double-click ExportBitmapResolution that you just created
   In the Value dialog box select Decimal and in the data box, type in 300 which is 300 DPI resolution (highest).
   Click "OK." It should look like below image.

7. Exit the Registry Editor and restart your computer.

Step 2: Export your slide as a high-resolution image

1. Open the PowerPoint presentation you want to export as image

2. Go to File > Save As

3. Choose the location to save the file.

4. In the Save as box, select the image format (e.g. JPEG format).

5. Click "Save" and select "Just This Slide" or "All Slides"

Your exported slides will now be in high resolution, making them perfect for detailed prints and high-quality displays. You can double-check this by right-clicking any of your exported JPEGs, and under "Details" menu you can see the image resolution.
