Reduce File Size in PowerPoint – Graphic Sizes Too

If you’re ever working on a PowerPoint presentation and notice that the file seems to get bigger for no reason, try this.

  1. Click File, Properties, General tab to see how large your file is. Close the dialog box.
  2. You can reduce the file size by up to 50 percent by resaving it under a different name. Click File, Save As, and rename the file.

Recheck the file size. If it doesn’t work the first time, try it again.

Compress Pictures to Make File Smaller. If you’ve embedded a lot of pictures, you can compress one picture or all of them. If you choose to compress all pictures, wait until you have inserted all of them so PowerPoint won’t attempt to recompress them.

  1. Click on the picture you want to compress, click to Show Picture Toolbar.
  2. Click the Compress Pictures toolbar button located on the Show Picture Toolbar (hold your mouse over each button to find it. It’s a square with a picture inside and four arrows pointing to each corner).
  3. Make desired selections.

If your file size doesn’t seem to be shrinking when you do the compress, turn off Fast Saves.

  1. Click Tools, Options, Save tab, untick Allow fast saves.
  2. Resave the file under a different name.
