Stretching text area on pdf

[Todd32817009vyaz]

Hi friends, I'm trying to stretch lecture slides. My lecturer hasn't exported their slides properly resulting in a very small area with the slide and the rest is blank. All I want to do is enlarge the slides to fill a quarter of the page each and essentially end up with four slides per page. When I crop all and drag, it doesn't enlarge the text. Is there a way to flatten? the slide and simply drag to enlarge whilst keeping the text searchable? Thanks in advance 🙂

In Acrobat DC Pro scale the pages with the preflight tool.

Thanks for the response. Is this the only way to enlarge the slides whilst maintaining their structure? No ability to drag and stretch?

Try this:

In Edit mode select the text and change the font size.

No. PDF files were never meant to be edited in this way, and doing what you described is certainly not possible with them.
