PowerPoint is great for designing leaflets, posters and other forms of advertising. It is a great, powerful but easy tool to generate your documents and graphics. High-end software like Adobe Photoshop or Adobe Illustrator is not needed. In this article, we will learn how to convert PowerPoint to JPEG.

Before you start creating high resolution or high definition presentations, there is an important option that you must set in PowerPoint, before you start importing and using your first image. We have spent a whole article on that. As a recap, in PowerPoint, go to File, Options, Advanced. And check the option Do not compress images in the file at the Image Size and Quality group. With this option set, your high resolution images, will remain high resolution, when they are stored within your presentation. When you forget this option, your high resolution images will loose its quality and high definition for sure on the first save.

For some occasions, you want to create a presentation in PowerPoint, and then export the presentation as individual images, an image per slide, for example to be used as images on a SD card on your television, as a cheap method to run the advertising in your shop.

Let’s see what will happen. Insert a high resolution image on your slide, or even set this image as your slide background.

The size of the original image was 4.08 MB, with a dimension of 5835 by 3890 pixels. When we save the presentation, it’s file size is 4.11 MB. So, we can conclude that no image information was removed, nor compressed by the PowerPoint save action.

Now click File, Save as. As file type, select JPG or even the uncompressed version of an image, BMP. Hit the Save button. Explore the generated image in your File Explorer.

You will see that your image probably has a dimension of 1280 by 720 pixels, while the original size was 5835 by 3890 pixels. How is that possible? The original size of the image in the presentation is kept when we save the presentation, while when we export a slide to an image, it drops to less than 25% of the original quality.

So, while the convert Powerpoint to JPEG worked, the image is not as high quality as we want.

Default export resolution

Well, that is the default resolution of PowerPoint when you export to images. So with a default of 1280 by 720 pixels, which corresponds to 96 dpi (dots or pixels per inch) , you have a lower image resolution than HD or high-definition quality of 1920 by 1080 pixels. That is a resolution that we don’t want to use for high-quality images for our advertising purposes. So we have to change that!

Change export resolution

There is a method to change the resolution of the images that you export in PowerPoint. The standard for high-quality images in the professional printing industry is set to 300 dpi. So we want our PowerPoint to JPEG conversion to be set to these printing standards.

To change the export resolution, use the registry editor. Click the Windows button and R on your keyboard, and type in regedit at the open option. Hit OK to execute the open command.

start the registry editor via windows key and R key
This will open the Windows Registry Editor for some special settings that you can change. It looks like this:
regedit registry editor opened

Use the tree view at the left and open the folders HKEY_CURRENT_USER, Software, Microsoft, Office.

Depending on the version of Office that you have installed (and are using), you have to open 14.0 for Microsoft Office version 2010, 15.0 for Microsoft Office version 2013 or 16.0 for Microsoft Office version 2016. Those are the internal version numbers as Microsoft have set them.

We are using Microsoft Office 2016, so we open the 16.0 node or folder.

After that, continue down to PowerPoint and then finally Options.

powerpoint advanced options in registry editor
In the pane at the right, right click and choose New, DWORD (32-bit) Value from the pop up menu.
add a new entry DWORD to the registry

Name this new entry ExportBitmapResolution and hit ENTER. Double-click this new entry and set the Base to Decimal and set the Value data to 300. Click OK to confirm. At this time already, this entry is physically added to the registry. There is no option to save this ‘document’ as you might expect with other type of documents.

When this setting is not present in the registry (this is the default situation), then a value of 96 is assumed and this results in an image export in a 1280 x 720 pixel resolution. This higher the value you use here, the higher your pixel resolution will be. As written before, 300 is a value that is commonly used for professional prints and advertisements.

Restart PowerPoint and open your last presentation again with that high-resolution photo inserted. Once more, click File, Save as and choose to export to the image format like e.g. JPG. Verify the image resolution of the generated file again and you will see that the export image now has a resolution of 4000 by 2250 pixels. This is a high-resolution exported image from your PowerPoint design and it much better looking that the original or default PowerPoint settings.
