How to Convert Multiple Embedded PNGs to JPEGs in PowerPoint File? - Filter PNGs by Size

PowerPoint is a powerful tool for creating presentations, and it allows you to insert various types of images into your slides. By default, PowerPoint supports the PNG image format, which is great for high-quality images with transparent backgrounds. However, sometimes you may need to convert multiple embedded PNGs to JPEGs in a PowerPoint file. In this article, we will show you how to do that easily.

Before we begin, it's important to note that converting PNGs to JPEGs may result in a loss of image quality, especially if the PNGs have transparent backgrounds or contain text. JPEGs use a lossy compression algorithm, which means that some image details may be lost during the conversion process. Therefore, it's recommended to make a backup of your PowerPoint file before proceeding.

Step 1: Open your PowerPoint file

Start by opening the PowerPoint file that contains the embedded PNGs you want to convert to JPEGs. You can do this by double-clicking on the file icon or by opening PowerPoint and selecting "Open" from the File menu.

Step 2: Select the PNGs you want to convert

In PowerPoint, each embedded image is treated as an individual object. To select multiple PNGs at once, hold down the Ctrl key on your keyboard and click on each PNG you want to convert. Alternatively, you can click and drag your mouse to create a selection box around the PNGs.

Step 3: Copy the selected PNGs

Once you have selected the PNGs, right-click on any of the selected images and choose "Copy" from the context menu. Alternatively, you can press Ctrl+C on your keyboard to copy the images.

Step 4: Paste the PNGs as JPEGs

Now, open an image editing software like Paint or Photoshop. Create a new image file by selecting "New" from the File menu. The new image file should have a white background and the same dimensions as your PowerPoint slide.

Next, paste the copied PNGs into the new image file by selecting "Paste" from the Edit menu. The PNGs will be pasted as separate layers or objects in the image editing software.

Finally, save the new image file as a JPEG by selecting "Save As" from the File menu. Choose the JPEG file format and give the file a name. Make sure to select a location on your computer where you can easily find the saved JPEG file.

Step 5: Replace the PNGs in PowerPoint

Now that you have converted the PNGs to JPEGs, it's time to replace the PNGs in your PowerPoint file with the new JPEGs.

Go back to PowerPoint and select the first PNG you want to replace. Right-click on the PNG and choose "Change Picture" from the context menu. A file selection dialog will appear.

Navigate to the location where you saved the JPEG file in Step 4. Select the JPEG file and click "Insert" or "Open" to replace the PNG with the JPEG.

Repeat this process for each PNG you want to replace in your PowerPoint file.

Filter PNGs by Size

If you have a large number of PNGs in your PowerPoint file and only want to convert certain ones based on their size, you can use a simple trick to filter the PNGs before converting them to JPEGs.

Follow these steps:

1. Make sure you have copied all the PNGs you want to convert to JPEGs as explained in Step 3.
2. Open a new PowerPoint file and paste the copied PNGs into the new file.
3. Go to the "File" menu and select "Save As". Choose a location on your computer where you can easily find the saved file and give it a name.
4. Close the new PowerPoint file without saving any changes.
5. Now, navigate to the location where you saved the new PowerPoint file. Change the file extension from .pptx to .zip. For example, if the file name is "presentation.pptx", rename it to "presentation.zip".
6. Extract the contents of the ZIP file to a new folder on your computer.
7. Open the extracted folder and navigate to the "ppt" folder. Inside the "ppt" folder, you will find a "media" folder.
8. Open the "media" folder, and you will see all the embedded PNGs from your original PowerPoint file.
9. You can now filter the PNGs based on their size and delete the ones you don't want to convert to JPEGs.
10. Once you have filtered the PNGs, follow Steps 4 and 5 from the previous section to convert the remaining PNGs to JPEGs and replace them in your original PowerPoint file.

By following these steps, you can easily convert multiple embedded PNGs to JPEGs in a PowerPoint file. Just remember to make a backup of your original file and be aware of the potential loss of image quality during the conversion process.
