I can’t read the text on some slides.
Sometimes the original slides for a presentation contain text that is very small and difficult to read. Consequently, in the process of converting the slides to a usable format for the Internet, this small text becomes illegible.
To enlarge the slide for easier viewing, click on the “Zoom” button (if available) located near the slide controls. This will launch a new window with a larger version of the slide. To enlarge the slide even more, click the “Zoom In” button (if available) located in the bottom right corner of the zoomed window.
Does this solve your problem? If not see some other options below.
