Step by Step Tutorial: Compressing Audio and Video in PowerPoint 2010

Before diving into the steps, let’s clarify what we’re about to accomplish. By following these instructions, you will reduce the size of your audio and video files in PowerPoint 2010, which can help with file management and ensure smoother playback during your presentation.

Step 1: Open your PowerPoint presentation

Open the presentation you want to compress the media files in.

Opening your presentation is the first step. Make sure you have saved all your work before proceeding with the compression process to avoid any data loss.

Step 2: Select the file you want to compress

Click on the video or audio file that you would like to compress.

Once you’ve selected the file, you’ll notice that the format-specific options become available in the menu ribbon, which is where you’ll find the compression tool.

Step 3: Access the compression settings

Click on the “Format” tab in the menu ribbon, then select “Compress Media”.

The “Compress Media” option is specifically designed to reduce the file size of your media without having to leave PowerPoint. It’s a convenient feature that can save you time.

Step 4: Choose the compression quality

Select the desired video quality from the options provided: “Presentation Quality”, “Internet Quality”, or “Low Quality”.

Each quality setting has its own benefits and trade-offs. “Presentation Quality” maintains the highest quality but offers the least compression, while “Low Quality” will give you the maximum compression but at the cost of video clarity.

Step 5: Wait for the compression to complete

After selecting your quality preference, PowerPoint will compress your media files. This may take a few moments depending on the size and number of files you’re compressing.

Once the compression is complete, PowerPoint will display how much space you’ve saved with the compression. It’s always a good idea to preview your video or audio to ensure the quality is still acceptable.


Reduced File SizeCompressing your media files can significantly reduce the overall size of your PowerPoint presentation, making it easier to share via email or upload to the web.
Smooth PlaybackWith smaller file sizes, your audio and video are more likely to play without hiccups, keeping your audience engaged.
Time SavingBy compressing within PowerPoint, you avoid the hassle of using outside software to optimize your media files, saving you precious time.


Quality LossDepending on the level of compression, you may notice a decrease in audio or video quality which could affect the effectiveness of your presentation.
Time ConsumingLarge files or numerous media pieces can take a while to compress, which could be inconvenient if you’re pressed for time.
Compatibility IssuesSome older or less common media formats may not compress as well or at all, potentially causing problems.

Additional Information

While compressing your media files in PowerPoint 2010 is generally straightforward, there are a few extra things to keep in mind. For starters, always make a backup of your original files before compression, just in case something goes wrong. It’s also worth noting that the more you compress a file, the lower its quality will become, so try to strike a balance between file size and clarity.

Another tip is to consider the purpose of your presentation when selecting the compression setting. If it’s for a professional setting, you may want to opt for higher quality despite the larger file size. However, for more casual or internal use, lower quality might be acceptable for the sake of convenience.

Lastly, remember that compression isn’t always necessary. If your presentation is running smoothly and file size isn’t an issue, you might not need to compress at all. But when sending that presentation via email or ensuring a smooth playback experience, compression in PowerPoint 2010 can be your best friend.
