Image Degradation on Saving

PowerPoint automatically compresses images when saving a presentation. This is generally “a good thing” in that it reduces the size of your file. However, if you are using high resolution photos, you may not want to lose that definition. You can prevent PowerPoint from compressing images in a presentation by following these steps:

  1. Select “Save as
    The “Save as” dialog box is displayed
  2. Click on “Tools” at the bottom left of the box
    Save options will be displayed
  3. Select the “Compress Pictures” option
  4. Click on the “Options” button
  5. Uncheck the “Automatucally perform basic compression on save

Uploading a PowerPoint File in Moodle

Q: My professor assigned us a PowerPoint presentation to upload to Moodle, but I cannot upload it – it is too big!

A: There are several reasons this might happen. Most often it is because of very large images or multimedia that have been included in the PowerPoint presentation. This is especially true of pictures added without resizing them from digital cameras. To fix this:

For Images:

  1. The best strategy is to resize your pictures before you put them in the PowerPoint presentation. Load you picture into a graphics editor such as PhotoShop and resize the image something close to 400 – 600 pixels wide and 70 -85 dpi.
  2. If you need the images to retain the higher dpi, you can try just resizing the image and leaving the dpi untouched.
  3. If the file is still too large, try compressing your entire PowerPoint presentation into a zip file. Upload that and people can download and unzip it.
  4. If that file is still too large, try “Saving As” a PDF file

If all of these options still fail to reduce your file to a size that can be uploaded, you have two options:

  • Contact your professor and ask them to request a larger file size limit in whatever onlince application (Moodle, Confluence, WordPress) they are using
    OR
  • Divide your file into smaller sections or chapters and upload each one individually

For Video and Audio:

  • Use a multimedia editor to compress your multimedia file before you embed it in PowerPoint
  • Break your presentation into smaller sections and upload them separately
  • More help compressing audio and video can be obtained from the LRC Lab  (fourth floor of Lovejoy)
