Frequently asked questions
Will compression reduce quality?
Higher compression levels reduce embedded image resolution and quality more aggressively. Low compression only optimizes file structure and won't visibly affect quality.
Why didn't my file get smaller?
Some PDFs — especially text-only documents — are already compact. We never return a file larger than your original.
