FAQ
Common questions.
Can I compress a PDF without losing quality?
Yes. Our Medium compression level reduces file size significantly while keeping text sharp and images visually identical. Use Low compression for maximum quality retention.
How much can I reduce a PDF file size?
Results vary by content. PDFs with large images can be reduced by 70–90%. Text-heavy PDFs typically compress by 20–50%. We show the before/after size so you always know exactly how much was saved.
Is there a file size limit for PDF compression?
We support files up to 100MB per upload. For larger files, splitting the PDF first and compressing each part separately works well.
Will compressing a PDF add a watermark?
Never. PDFGeneratorFree does not add any watermarks, logos, or branding to your compressed files. What goes in comes out — just smaller.
