FAQs – Compress PDF

Does compression reduce PDF quality? ▼
At "Recommended" level, quality loss is minimal and usually invisible to the eye. Higher compression reduces image quality more but makes smaller files.
Is my PDF safe? ▼
Yes. Files are processed locally in your browser using PDF-lib. No data is sent to any server.
How much can I compress a PDF? ▼
Compression rates vary. PDFs with many images can be reduced by 50-80%. Text-only PDFs compress less since text is already compact.
