Frequently asked questions
Does compression reduce quality?
You choose the level: a light setting keeps things crisp, a stronger one favours the smallest size.
Do my documents stay private?
Yes — compression runs in your browser, with nothing sent to a server.
How much smaller will it get?
It depends on the content (images, scans). Image-heavy PDFs compress the most.
