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

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

Follow me irl for more compression techniques.

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

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