PowerPoint Error ‘Out of Memory’: Causes and Workarounds

When you see the “Out of Memory” error in PowerPoint, your presentation file is usually not too large. The error often appears when PowerPoint cannot allocate enough system memory to perform an action like inserting a high-resolution image or running a complex animation. This problem stems from how 32-bit versions of PowerPoint handle memory limits or from system resource exhaustion caused by large media files. This article explains why the error occurs and provides specific workarounds to resolve it.

Why PowerPoint Displays the Out of Memory Error

The error occurs when PowerPoint requests more memory than is available from the operating system. In 32-bit versions of Office, PowerPoint can use only up to 2 GB of virtual memory regardless of how much RAM your computer has. This limit is a hard ceiling imposed by the 32-bit architecture. When your presentation contains large uncompressed images, embedded videos, or many complex vector graphics, PowerPoint may exceed this limit and show the error.

Another common cause is the accumulation of image editing data. Each time you crop, resize, or apply effects to an image, PowerPoint stores the original high-resolution version along with the edited version. This hidden data can balloon the file size and memory usage. The error can also appear when you have many programs running simultaneously, leaving insufficient RAM for PowerPoint.

Workarounds to Resolve the Out of Memory Error

The following workarounds target the root causes of the memory error. Apply them in the order shown for the best results.

Discard Image Editing Data

1. Open File > Options
   In PowerPoint, click the File tab, then select Options at the bottom of the left pane.
2. Go to Advanced
   In the PowerPoint Options dialog, click Advanced in the left sidebar.
3. Find Image Size and Quality
   Scroll down to the Image Size and Quality section. It is near the bottom of the Advanced options list.
4. Enable Discard editing data
   Check the box labeled Discard editing data. This removes stored original image data that is no longer visible. Click OK to apply the change.

Compress All Pictures in the Presentation

1. Select any picture
   Click any image in your presentation to activate the Picture Format tab on the ribbon.
2. Click Compress Pictures
   On the Picture Format tab, click Compress Pictures in the Adjust group.
3. Choose resolution
   In the Compress Pictures dialog, select a lower resolution such as 150 PPI or 96 PPI. Uncheck Apply only to this picture if you want to compress all images in the presentation.
4. Click OK
   Click OK to compress the images. PowerPoint will reduce the file size and memory footprint immediately.

Reduce the Use of Embedded Media

Embedded videos and audio files consume significant memory. Instead of embedding, link to media files stored on your computer or network drive. To link a video, go to Insert > Video > Video on My PC. In the Insert Video dialog, click the arrow next to the Insert button and select Link to File. This keeps the video file separate from the presentation and reduces memory usage during editing.

Close Other Programs and Restart PowerPoint

Before working on a large presentation, close all unnecessary applications. Web browsers with many open tabs, design software, and virtual machines consume RAM that PowerPoint needs. After closing other programs, restart PowerPoint to clear its memory cache.

Switch to 64-bit PowerPoint

If you have a 64-bit version of Windows and a 64-bit version of Office, PowerPoint can use more than 2 GB of memory. To check your version, open File > Account > About PowerPoint. If it says 32-bit, you can uninstall Office and reinstall the 64-bit version from your Microsoft account. This is the most effective long-term solution for users who regularly work with large presentations.

If PowerPoint Still Shows the Out of Memory Error

PowerPoint Crashes When Opening a Specific File

If the error appears only with one presentation, the file may be corrupted. Try opening the file in PowerPoint Online at office.com. If it opens, save a copy to your local drive. This can remove corruption. Alternatively, use the Open and Repair feature: go to File > Open, select the file, click the arrow next to the Open button, and choose Open and Repair.

PowerPoint Runs Out of Memory When Adding Transitions

Complex transitions like Morph or 3D animations can trigger the error. Disable hardware graphics acceleration by going to File > Options > Advanced. Under Display, check Disable hardware graphics acceleration. Click OK and restart PowerPoint. This forces PowerPoint to use software rendering, which uses less memory.

The Error Appears on a New Blank Presentation

If the error occurs even with a blank presentation, your PowerPoint installation may be damaged. Run the Office repair tool: go to Control Panel > Programs > Programs and Features. Select Microsoft 365 or Office, click Change, and choose Quick Repair. If that does not help, run an Online Repair.

32-bit vs 64-bit PowerPoint: Memory Limit Comparison

Item	32-bit PowerPoint	64-bit PowerPoint
Maximum usable memory	2 GB	Up to system RAM limit (typically 8 GB to 2 TB)
Compatibility with older add-ins	Supports all 32-bit add-ins	May not support older 32-bit add-ins
File size handling	Struggles with files over 200 MB	Handles files over 500 MB without memory errors
Operating system requirement	Works on 32-bit and 64-bit Windows	Requires 64-bit Windows

The 64-bit version removes the 2 GB memory ceiling that causes most Out of Memory errors. If you rely on third-party add-ins, verify they have 64-bit versions before switching.

You can now reduce the memory usage of your PowerPoint presentations by discarding editing data, compressing images, and linking media files instead of embedding them. For persistent errors, consider switching to 64-bit PowerPoint to eliminate the 2 GB memory limit. As an advanced tip, use the Compress Media feature on the File > Info menu to reduce the size of embedded audio and video files without affecting their playback quality.
