Save PowerPoint slides as high-resolution images

In this article, we cover the process of exporting PowerPoint slides as images at high resolution and present a new solution that gives greater precision over image resolution and output formats. This post covers both the direct PowerPoint method and an easy and powerful option using a tool called Slidewise.

Export slides (PowerPoint method)

To export slides using the built-in PowerPoint feature, you have to choose to export all slides, or just the current slide. You cannot select specific slides and extract only these to images using PowerPoint. To control the precise dimensions of your exported images, you need to edit your registry. Microsoft provides instructions for editing your registry to export at higher resolutions.

If this is a one-off requirement and/or you are happy editing your registry, just follow the instructions above, and then follow the steps here to save a slide as an image from PowerPoint.

Export slides (Slidewise method)

To export slides easily and flexibly with complete control over image resolution and slide selection, use Slidewise. Download the trial for 30 days of full, unrestricted access. Simply install the software, pick your slides, and convert them into high-resolution images in just a few minutes.

Slidewise gives you 2 key advantages over using PowerPoint:

1. You can choose to export selected slides only

2. You have full control over the size of your exported images

Once installed, select the slides that you want to export from the thumbnail panel, or in the Slide Sorter view (you can choose any number of slides from 1 to all of the slides in the deck). Then right click on the slide thumbnail and choose Export Slides As, or click the button on the Slidewise ribbon

This opens the Export Selected Slides dialog, where you can choose the format you’d like to export to - either PNG, JPEG, PPTX or PDF.

For the image formats, you can then choose the Image size that you’d like to target. You have 4 unit options to choose from when specifying the size:

1. Pixels

2. Percent

3. Inches

4. Centimeters

Pixels

Enter the width or height in pixels and the other dimension will recalculate to match. Slidewise defaults to 1920px x 1080px based on a standard 16:9 presentation. If your presentation has different dimensions the default will adjust accordingly.

NOTE: The aspect ratio is always locked to prevent your images from  becoming skewed. If you need to change the aspect ratio, you will need to adjust the size of the presentation.

Percent

This option allows you to skip the calculations if you simply want the slides to be, for example, scaled up to 300%, or scaled down to 50%.

Inches and Centimeters

These units are provided so you can export images to match a specific physical size, for example, if they are to be placed into a document for print. Set the Width, Height and Resolution (DPI) to your requirements and Slidewise will automatically calculate the pixel dimensions required to meet your physical dimensions.

Once you are happy with your dimensions, click the Export button and choose where to save the exported images. Images will be saved with the presentation name followed by the slide number e.g. Presentation name.pptx - Slide 0014.png.

Export selected slides as PDF/PPTX

All you need to do with this option is to click Export and choose where you want to save your new PDF or PPTX file and what you want to name it.
