Frequently asked questions
How does the compression work?
Scan-based pages are re-rendered as compressed images, which dramatically cuts the size of heavy, image-only PDFs.
Is my PDF uploaded?
No. Compression happens entirely in your browser and your file stays on your device.
Will quality drop?
You choose the trade-off with a compression level. Higher compression gives lighter files, while lower compression keeps pages sharper.
Your files never leave your device
