What gets smaller, and what doesn’t
Most big PDFs are big because of the photos or scans inside them. We re-save those pictures at a lower quality and size; text, lines and fonts are copied unchanged, so they stay sharp and selectable.
A PDF that is mostly text is usually small already and may not shrink. In that case we tell you and you keep your original.
