Optimizing PDF output file sizes

[fact0real]

Hello all,

The current issue with the output PDF files is their large size, which can be significantly reduced by at least 90% through optimization techniques for efficient storage and transmission in low capacity Remarkable devices.

For example look the following files:

Lists.pdf 2.4 MB
Sundays_L12.pdf 1.3 MB
Lists_L12.pdf 2.1 MB

Hello. Blank background versions for "leafs" pages (most numerous) is the simplest solution. Another is using PDF patterns if I'm right about name. I've tried those but they caused to show loader thing in the center of screen on navigation that I try to avoid. Anyway what are constraints (non abritrary)? There is no point in optimizing without measuring/defining first.
