Frequently Asked Questions

Is my PDF file secure?
Yes, completely secure. All processing happens directly in your browser. Your PDF files are never uploaded to any server.
How much can I reduce the file size?
Results vary depending on the PDF content. PDFs with many images typically see the best results. Text-heavy PDFs may see smaller reductions.
Will compression affect the quality?
The 'Low' compression maintains best quality with moderate size reduction. Higher compression levels may slightly reduce image quality for better size savings.
Why is my PDF not getting smaller?
Some PDFs are already well-optimized. If your PDF contains mostly text or is already compressed, there may be limited room for further reduction.
