It is common practice to include images within MS PowerPoint (PPT) presentations to demonstrate key points and support classroom discussions. Often, these images are of high quality and resolution. However, when these images are included in the PPT file, they become a part of the file (a process called embedding), which increases its overall size.

In addition, many faculty members like to share their PowerPoint presentations in Blackboard, but they prefer to do so as PDF files. If the PowerPoint presentation is very long, or has many image files, this can cause the PDF file to become so large that it becomes difficult to upload into Blackboard. If you have large PDF files to upload to Blackboard, we have a workaround for you.

Mac Users

  1. Save the PowerPoint as a PDF or export the PowerPoint as a PDF.
  2. Using the Preview app on your Mac, open the PDF, then choose File>Export.
  3. Click the Quartz Filter menu, then choose Reduce File Size.
  4. When you are prompted to give the file a name, be sure to change the name of the file so you know which PDF version is the original size and which is the reduced file size.

PC Users

  1. Save the PowerPoint as a PDF or export the PowerPoint as a PDF.
  2. Using Adobe Acrobat Pro, open the PDF file.
  3. Click on File in the editing ribbon. In the drop down menu click on Save As Other, and then click on Reduced Size PDF.
  4. Click OK to reduce the file size.
  5. In the file name, be sure to change the name of the file so you know which PDF version is the original size and which is the reduced file size.

You now have a smaller file that Blackboard will have an easier time uploading.
