How to Compress Pictures in Powerpoint: A Step-by-Step Guide

Got a PowerPoint presentation with images that are too big? No worries, you can easily compress pictures in PowerPoint to make your presentation file size smaller. Whether you’re trying to save space on your computer or make your presentation easier to share, compressing pictures can help. Just follow these simple steps, and you’ll have your images compressed in no time.

Step by Step Tutorial: How to Compress Pictures in PowerPoint

Before we dive into the steps, let’s briefly discuss what we’re aiming to achieve. By compressing pictures in your PowerPoint presentation, you’re reducing the file size of the images without significantly impacting their quality. This allows for easier sharing and storage of your presentation. Here’s how you do it:

Step 1: Open your PowerPoint presentation

Open the PowerPoint presentation that contains the pictures you want to compress.

When you open your presentation, make sure you’re on the slide with the picture you want to compress. If you have multiple pictures to compress, you can repeat the process for each one.

Step 2: Select the picture

Click on the picture you want to compress.

Once you’ve selected the picture, you’ll notice that the “Picture Format” tab appears on the ribbon at the top of the PowerPoint window. This tab contains all the tools you need to edit and compress your picture.

Step 3: Click on the “Picture Format” tab

Navigate to the “Picture Format” tab.

In the “Picture Format” tab, you’ll find various options to adjust your picture, including cropping, adding effects, and, most importantly, compressing the image.

Step 4: Click on “Compress Pictures”

Find and click the “Compress Pictures” button in the “Adjust” group.

The “Compress Pictures” button usually has an icon that looks like two mountains with a downward-pointing arrow. Clicking this button will open a new dialogue box with compression options.

Step 5: Choose your compression options

In the dialogue box, select the compression options that best fit your needs.

You’ll have a few options in this dialogue box, including whether to apply the compression to just the selected picture or all pictures in the presentation. You can also choose the resolution you want for the compressed picture, with lower resolutions resulting in smaller file sizes.

After you complete these steps, your selected picture will be compressed according to the options you chose. Your PowerPoint presentation will now have a smaller file size, making it easier to manage and share.

  • Consider the purpose of your presentation when selecting compression options; higher resolutions may be necessary for professional or printed presentations.
