How to reduce the size of a Google Slides presentation?

While Google Slides, being an online presentation platform, doesn’t take up room on your Google Drive, that handiness only goes so far. If you need to download the presentation to share with others, you may feel the need to lower the presentation’s size to reserve space and avoid running into space issues.

In this tutorial, you’ll learn a few different methods to reduce the size of a Google Slides presentation to make it more manageable for download.

Reducing the ratios

One thing you can do to lower the file size of a Google Slides presentation is by altering the dimensions. While it is a small change, it can make a difference.

  1. First, go up to File in the top left of your screen.
  2. Then go down to the “Page setup” option.

3. When the window appears, click the dropdown arrow and select “Custom.” Then you can enter in the particular dimensions you need your presentation to be.

Keep in mind that the lower the dimensions, the smaller the file, but reducing them too much may lead to a Google images issue.

Export as a PDF

One of the easiest methods of reducing the size of a Google Slides presentation is transforming the file into a PDF.

To make this transformation, follow these three basic steps:

  1. Go to “File” located at the top left of your screen.
  2. Scroll down to the “Download” option.
  3. Choose “PDF Document.”

Keep in mind that although this way is the most basic, this type of file cannot be altered. This option is useful if you’re simply trying to share the presentation, but not helpful if you need it to present on a screen or share with a team to edit.

Reduce the image size

Another way to lower the space the presentation takes up is to reduce the Google image size. The quickest way to do this would be to choose the right image file from the beginning when the image is inserted into the slide.

To insert an image that takes up less space, follow these steps:

  1. Click “Insert’ on your toolbar.
  2. Choose “Image.”
  3. Then choose to “Upload from computer.”

4. To ensure the image is the most condensed, choose the “JPG” format rather than the larger file option “PNG.”

Embedding videos

Suppose you have videos inserted in your Google Slides presentation, similarly to how you reduce the Google image size. In that case, you can reduce the space the videos take up by embedding them. Embedding is a smarter route to minimize space taken up overall instead of inserting it when you go to download your slides.

To insert an embedded video, follow these steps:

  1. Go up to “Insert.”
  2. Choose “Video.”
  3. Find the desired video from YouTube, as a URL, or from your Google Drive, and select it.

Choosing to utilize one or all of these skills will help lower the amount of space your Google Slides presentation takes up when it’s downloaded.

  1. Aside from “just pick a better image”, is there a way to reduce file size of an image that’s already there? It’s a few clicks in PowerPoint but a huge headache in Google Slides. Can’t even same

    1. Good evening! No, unfortunately Google Slides does not yet have the ability to reduce the size of already inserted images. I usually reduce the size of the image ahead of time using the Tinypng service.

  2. Can I compress videos directly in Google Slides or do I need to use other programs?

    1. Unfortunately, Google Slides does not provide tools to compress videos. It’s best to compress the video using third-party programs before inserting it into your presentation.
