Most of the work you do in PowerPoint will likely be exported in high resolution (high res), whether this is for a widescreen presentation, a printed document, or a high-definition video. Let’s at a look at how you can check and set up your files for high res exports so that you’re producing the best quality work possible.
High Res PDF
To export a high res PDF, first ensure that all the images in your PowerPoint document, if any, are already at their highest resolution. To do this, click on one of your image files in the document, then in Picture Format, click on Compress Pictures.
In this window, select the highest resolution possible; HD 330 ppi is preferable, or High Fidelity, which will preserve the original quality of the image, but Print 220 ppi will also be okay if that is the highest quality the original image was imported in. Anything less than this can become pixelated when printed or viewed onscreen. Then uncheck the Apply only to this picture setting, so that this will be applied to all the other images in your document. Then click OK, which will convert all your images to their highest quality.
To ensure everything is also exported at their highest quality, check your Adobe PDF export settings. Go to File, and then Print. In this menu, change the Printer to Adobe PDF, and then click Printer Properties to access the settings. You’ll get a pop-up window for Adobe PDF Document Properties. Now your Default Settings will be on Standard. To check exactly what these settings are, click Edit.
Now you’ll get another window called Standard Adobe PDF Settings. These are where all the detailed settings of your PDF exports are. Have a look through all the sections in this window to find out exactly how everything is exporting. We’re focusing on Images, so click on the Images subfolder to bring up all your image export settings.
In these settings, you’ll want to ensure your Colour, Greyscale and Monochrome images are exporting at least at 300 dpi for a high quality print. Once you’re done, either Save As to save out a new custom setting, or just click OK for this one document. Then click OK again to exit the Adobe PDF Document Properties Window. Now when you click Save as Adobe PDF, PowerPoint will use these settings to export your file.
High Res Video
Exporting a high-res video is quite simple. You’ll find your video export settings in File, then Export, then Create a Video. Here in the drop-down menu, you can see the different export options for video. For a high quality render, Full HD 1080p is the recommended minimum setting you should use. This will look good on most monitors and projectors. For even higher quality, you can choose the Ultra HD 4K export, but know that this will take a lot longer to render out.
Once you have chosen a setting, click Create Video. Now your video will begin to render. You can see the loading bar at the bottom of your normal slide view. Once the bar is completed, then your video will have finished rendering.
High Res JPG/PNG
Changing the export settings for a jpg or png is a little more complex than the previous processes. The default export for these images is 96dpi. If you want to change this, you’ll have to change the settings in the PowerPoint system registry.
First, ensure you’ve exited all Windows programs to avoid corrupting any working files. Then right-click on your Windows Start button and choose Run from the menu that pops up.
A new window will pop up. Where it says Open, type ‘regedit’. Then hit OK.
Now a file browsing window will open. To navigate to the PowerPoint system registry, use the folders on the left.
First click HKEY_CURRENT_USER.
Then choose the Software subfolder.
From that menu, Microsoft, then Office.
Now choose the highest number in these subfolders- this is your most updated version of PowerPoint. For most of you, it should be 16.0. Then click PowerPoint, and finally Options.
Now in the menu at the top, click Edit, then hover over the New button. Select DWORD Value from the dropdown menu there. This will create a new file in Options and automatically ask you to enter a name.
Type ExportBitmapResolution then hit Enter to finish renaming.
With ExportBitmapResolutions still selected, click Edit again, then Modify. This will open a new popup window.
Select the Decimal setting first. Now you can enter your desired resolution in the Value box. For most of you, this will be 300, which is the standard print resolution. Then click OK.
Exit the Registry Editor by clicking File, then Exit.
Now when you export slides as jpegs or pngs, they will export at your new resolution.
You can check this afterwards by right clicking your jpeg and clicking Properties. The dpi will be listed under Details.
If that was a little too complicated for you, an alternative is to export to a high-res PDF first, then exporting JPGs and PNGs from there.
Open your PDF, then click File, Export to, then Image. From there, choose any of the image file formats you need. You can adjust the resolution in the browser window that pops up when you click on Settings.
On the other end of the spectrum, we’ve got compressing PowerPoint files, reducing the features and quality from high res to something more manageable, which is great for sharing a PowerPoint file across Teams or with other users.
