Condense removes dead-weight, optimizes images, and subsets fonts - best for most PDFs. Photon converts pages to images - ideal for photo-heavy/scanned PDFs but makes text non-selectable.
Balanced (recommended) offers great size reduction with minimal quality loss. Use Light to preserve maximum quality, Aggressive for smaller files, or Extreme for maximum compression.
