Will compressing a PDF reduce its quality?

Our PDF compressor uses smart compression that significantly reduces file size while preserving readable quality for text and images.

Is there a file size limit for PDF compression?

No strict limit — compression runs entirely in your browser so it depends on available memory. Most PDFs up to several hundred MB work fine.
