Stupid BUT: making the font in LibreOffice bigger saves space. so having 11 is readible but by changing the font size to like 500 it can save some mb per page
I dont know how it works, i just noticed it at some point

Edit: i think it was kb, not mb

per page

I mean, yes. obviously.

If you had 1000 bytes of text on 1 page before, you now have 1byte per page on 1000 pages afterwards

Have a macro that decreases all font size on opening and then increases all again before closing.

Follow me irl for more compression techniques.

You could always diff the XML before and after to see what's causing it.
