Frequently Asked Questions
How does PDF compression stay private?

It depends on the level you choose. Balanced and Strong modes can reduce image quality to make the file smaller, while Light mode keeps better quality with smaller size savings.
Does this work on large PDFs?

Is this PDF compressor free?
