How do I compress a PowerPoint presentation?

To compress a PowerPoint presentation, follow these steps:

1. Open the PowerPoint presentation that you want to compress.
2. Click the “File” tab in the ribbon, and then click “Save As” in the left sidebar.
3. In the “Save As” window, select a location to save the presentation.
4. In the “Save as type” field, select “PowerPoint Presentation (*.pptx)” from the dropdown menu.
5. Click the “Tools” button in the “Save As” window and select “Compress Pictures” from the menu.
6. In the “Compress Pictures” window, choose the desired resolution and compression options. You can choose to apply the compression to all pictures in the presentation or only to certain ones.
7. Click “OK” to apply the compression.
8. Click “Save” to save the compressed presentation.

By compressing the pictures in the presentation, you can reduce the file size of the PowerPoint and make it easier to share or upload. However, be aware that compressing the pictures may also reduce their quality, so you may want to experiment with different compression settings to find the right balance between file size and image quality.
