One file at a time

Rasterize re-renders each page as a compressed image and rebuilds the PDF — it shrinks the most, but text stops being selectable/searchable, so quality depends on the level you pick. Bumping the level up (or targeting a larger size) preserves noticeably more detail. Optimize only keeps every page as real, sharp vector text and just rebuilds the file's internal structure more efficiently — savings are smaller, but there's zero quality loss, so it's the better choice for text documents that just look a little blurry after compression.

Works best on photos with a clear subject (people, products, animals). Fine detail like flyaway hair or busy edges may come out a little rougher than a manual cutout.
