Hi Zixuan,
- Do you mean you choose File>Export to export the presentation as a pdf file?
A: no, I go to File>Print>PDF dropdown>Save as PDF.
- Please let us know the size of that presentation.
A: The presentation size is 2.1 MB. It is a pptx file.
- Please confirm whether this behavior occurs with all the presentations. You may create a new file to test.
A: Yes it occurs with all presentation. As an example, I printed different presentation. The pptx is 3.1 MB. The pdf I produced on Jan 8, 2018, 13:11 is 324Kb. The pdf I produced today is 1.2 Mb. There was no changes made to the presentation. Although
the problem is not that severe in this case, the size of pdf produced are consistently bigger (5x to 30x)
- Is there any special content in that presentation like pictures or video?
A: no videos, but several pictures, mostly graphics. Few ppt animations to make images or bullets appear.
5: Please provide your OS version as well.
macOS High Sierra version 10.13.2 Supplemental installed.
Thank you,
Vincent
