If you want to only share specific pages of a large PDF file, you have a couple of options:
1. Use screenshot to capture 1 section of a PDF you want to share.
Using screenshot is a very quick and flexible way of sharing material on your device. All you need to do is open up the desired PDF on your computer and then take a screenshot of the material you want to be shared.
To take a screenshot on Mac devices hold down ctrl-cmd-shift-4 and then press cmd-v to paste into your Room.
On a Windows device use the Snipping Tool: https://support.microsoft.com/en-gb/help/13776/windows-10-use-snipping-tool-to-capture-screenshots
Shortcut is windows-shift-s and then ctrl-v to paste.

2. You can use a Split PDF tool
If you've got a large PDF on your device but only want to share a section of it, rather than uploading the whole thing you can split it and only upload the relevant part.
Here's a link to a tool which will let you split the PDF: https://smallpdf.com/split-pdf
