Frequently Asked Questions
How does compression work?
Our tool uses PDF.js and PDF-lib to render pages, optimize images, and rebuild a smaller PDF. All processing is done locally in your browser.
Are my files secure?
Absolutely. Files never leave your device. Everything happens client-side, ensuring complete privacy and security.
What do the levels mean?
Extreme: 72 DPI, max compression. Recommended: 144 DPI, balanced. Less: 200 DPI, highest quality retention.
Can I compress multiple PDFs?
Currently, we process one file at a time for best performance. Batch processing is on our roadmap.
Will text remain searchable?
Canvas-based compression renders pages as images, so text becomes non-selectable. This is the trade-off for maximum size reduction.
Is it mobile friendly?
Yes! The tool is fully responsive and works on smartphones and tablets. Compress PDFs on any device.
How long does it take?
Most files are processed within seconds. Larger files or extreme compression may take longer depending on your device.
Is the output a standard PDF?
Yes! The compressed file is a fully compliant PDF that works with all readers including Adobe Acrobat, browsers, and mobile apps.
