Microsoft PowerPoint, a part of the Microsoft Office suite, is a presentation program released on April 20, 1987.
The PowerPoint software allows users to create dynamic slideshows with texts, tables, charts, videos, audios, images, etc. It is suitable for projectors or big-screen TVs. Therefore, a lot of religious, corporate, and educational organizations prefer to use this tool to introduce visual information to groups or individuals. Some companies even regard it as a basic market skill.
Although you can make PowerPoint presentation interesting and powerful by inserting images, audios, and videos, it could be annoying that these media files would make your PowerPoint file larger. It takes up more disk space and might reduce playback performance. In addition, users might fail to send an email with a PowerPoint file as an attachment due to exceeding the file size limit.
In the following contents, you can learn about some tips on how to reduce PowerPoint file size.
Tip 1: Use PPTX Format for Your PowerPoint File
PPTX format was released by Microsoft in Office 2007. It has replaced the PPT format which was used by Microsoft PowerPoint previously, and it becomes the default format when users create a file with modern versions of PowerPoint. PPTX format compresses all the content within the PowerPoint file and it makes the file smaller than that using the PPT file type.
If your PowerPoint file is of PPT format, you should convert it to PPTX format to reduce PowerPoint file size. You just need to:
- Open the target file and click File from the top menu.
- Select Save as and select a location.
- In the pop-up window, select PowerPoint Presentationfor Save as type Then your PowerPoint file will be saved in PPTX format.
In my example, I convert my file to PPTX format and the file size is reduced by 1695KB. This should be an easy way to reduce PowerPoint file size, but the file size is depended on the contents inside the file eventually. If the PPTX file is still too large or your file has been created with PPTX format already, here are more tips that you might need in the following parts.
Tip 2: Insert Your Pictures Instead of Copying and Pasting
The JPG (Joint Photographic Experts Group) format is a lossy compressed file format for pictures. Usually, a picture of JPG takes less storage space than that of BMP (Bitmap) and PNG (Portable Network Graphic).
When you copy a picture and paste it to a PowerPoint file, the picture might be reformatted to BMP or PNG, which makes your PowerPoint file larger finally. So, you’d better add the picture to PowerPoint with the insert function which maintains the original format of the involved pictures.
When you save an image, you need to select an image format for it. If you choose between the PNG and JPG, learning the difference on PNG vs JPG is vital.
Tip 3: Do Not Edit Images in PowerPoint
Before inserting a picture in PowerPoint, you’d better make sure you don’t need to make any further edits for it. Any edits for the picture within the PowerPoint file will be saved as a part of the file, which means that a lot of extra stuff would be stored.
For example, when you change a colorful picture to black and white, PowerPoint retains the full-color image at the same time.
Therefore, if you need to edit a picture, please use an image editor and then insert it in PowerPoint. This could help you to reduce PowerPoint file size.
Tip 4: Compress Images in PowerPoint
Another method to reduce the picture size in a PowerPoint file is to compress the picture. You can compress images in PowerPoint one at a time or all at once. To compress all the images in the PowerPoint file, you need to:
Step 1: Click File from the top toolbar and select Save As. Then select the folder where you want to save the compressed file.
Step 2: Click the Tools option which is next to Save button. In the pop-up menu, select Compress Pictures.
Step 3: In the pop-up window, select “E-mail (96 ppi): minimize document size for sharing” under Resolution section. Then click OK to confirm that you want to compress pictures in PowerPoint.
Step 4: Click Save to save the compressed PowerPoint file.
If you want to compress a specific picture, you just need to select the picture in PowerPoint. Then click Format from the top toolbar and select Compress Pictures.
Tip 5: Remove Personal Information
Microsoft Office stores your personal information and hidden properties of your PowerPoint file, such as the author name, document properties, etc. Remove them could also help you to reduce file size in PowerPoint. Here are the detailed steps.
Step 1: Click File and select Info.
Step 2: Click Check for Issues. In the pop-up menu, select Inspect Document.
Step 3: The Document Inspector window will pop up, and you should make sure the “Document Properties and Personal Information” option in the list has been checked. Then click Inspect.
Step 4: In the following window, click Remove all for “Document Properties and Personal Information”.
Then save the file and it should be smaller. This could also help you when you need to prevent others from viewing your personal information for confidentiality.
If you find this doesn’t reduce the file size, please move on to the next tip.
Tip 6: Do Not Store a Thumbnail
PowerPoint allows you to save the thumbnail image so that you can preview the file when you search it in File Explorer. It is a useful feature to help you find the PowerPoint file you want quickly when there are many files with similar names, but this could increase the PowerPoint file size.
To disable the feature, you can:
Step 1: Click File > Info.
Step 2: On the right-hand side, click Properties and select Advanced Properties.
Step 3: In the pop-up window, switch to Summary tab. Then uncheck the option Save preview picture.
Step 4: Click OK to save the changes. Then save the PowerPoint file.
In my case, the file size is reduced by 10KB for me after I disable the thumbnail preview feature. It’s a pretty small save and might not help you. But if you have tried all the other tips and you are still unsatisfied with the PowerPoint file size, you can try this method.
Tip 7: Upgrade Your Storage Device
If it is hard for you to reduce PowerPoint file size and your disk is running out of space, which makes you unable to store more data on the disk, you might need to upgrade your disk to a larger SSD or HDD.
To replace your old disk with a larger one, you’d better transfer all the data. MiniTool Partition Wizard should be a helpful assistant. Here is how to migrate all the data on the old disk to the larger one with it. Please connect the larger disk to your PC and follow the steps below.
Step 1: Download MiniTool Partition Wizard by clicking the button below. Then install and launch it. To copy the system disk, you need to pay for the Pro Ultimate edition.
Step 2: When you get the main interface, click Migrate OS to SSD/HD Wizard under Wizard section in the left action panel.
Step 3: In the pop-up window, select Option A and click Next.
Step 4: In the following window, select the larger disk you prepared as the destination disk to store the copied data and click Next to continue.
Step 5: After selecting the destination disk, you can modify the Copy Options and Target Disk Layout. For an SSD, you’d better check Align partitions to 1MB. Then click Next.
Step 6: Read the pop-up note carefully which reminds you how to boot from the larger disk. Then click Finish. When you go back to the main interface, click Apply to execute the pending operations.
After copying the data, you can install the larger SSD or HDD to your PC and boot from it. You should get a lot of free space and you don’t need to reduce PowerPoint file size to save storage space now.
Further Tip: Extend the Drive Where the PowerPoint File Is Stored
