Why didn't my file get much smaller on Low?
Low only optimizes the file structure without touching images. For image-heavy PDFs, try Medium or High.
Will Medium/High affect quality?
They re-encode pages as images at a lower quality to save space, so text becomes non-selectable and quality is reduced.
