I have a PowerPoint file which exceeds the 20MB limit, what can we do to reduce the file size without removing slides or splitting up presentation?
It may be that your PowerPoint consists of many large images. Try compressing the images of your slides with PowerPoint to reduce the file size: Open PowerPoint presentation file Click File – Save As Click Tools from the upper right hand corner of “Save As” dialog box Select “Compress Pictures” Change Resolution to “Web/Screen (96dpi)”.
