About this V1

Lossless Optimize preserves the original PDF structure and avoids intentional image-quality reduction. Balanced and Maximum rebuild pages as compressed images for stronger file-size reduction, so selectable text, links, forms and other interactive features may be lost.

Digitally signed PDFs are intentionally not modified, because rewriting a signed PDF would invalidate its signature.
