One of the most commonly asked questions both online and offline is how to compress a PowerPoint presentation. Here's how:

Compress your images

Applies To: PowerPoint for Office 365, PowerPoint 2016
Reduce
    1. Select the image you want to compress. If you want to compress all images, click on any image.
    2. Go to the 'Format' menu displayed.
    3. Select the 'Compress' button under 'Picture Tools'.


  1. Select if you want to compress only the selected image or all images.
  2. Select one of the following in the 'Picture Quality' box:
    1. Print (220 ppi) - For printing purposes;
    2. On-screen (150 ppi) - For screen viewing - We recommend going for this option. If you can't check it, it means your images are below 150 ppi and you need to find higher-quality ones;
    3. Email (96 ppi) - For email sending;
    4. Click Use original quality - To keep the current resolution of the image/images and minimize changes.

Pro Tip 1: Resize the image before you insert it into your presentation. If you're downloading it from a free stock photo website, don't automatically download the highest resolution. Choose the size you need - for example, if you want to use the image for the full slide, you need to download the 2000x1300 px version, or something close to that. The goal is to get it at the smallest resolution while still retaining a qualitative aspect. If you have a very large image, use an imaging editing tool like Adobe Photoshop to resize it.

Pro Tip 2: If you’ve used the 'Crop' function for any of your images, you can further reduce the file size by checking the 'Delete cropped areas of pictures' box.

Pro Tip 3: You can also have PowerPoint automatically compress images within any future presentation. Go to File -> Options -> Advanced. Scroll to 'Image Size and Quality' and check 'Discard editing data'. Choose an appropriate target PPI value, which will be used to downsample any images you add thereafter.

Pro Tip 4: Un-check 'Apply only to this image' to speed up the process.
