Frequently Asked Questions
Common questions and answers regarding Document Scanner:
Is this document scanner safe for sensitive or financial documents?
Yes, 100% safe. Since ScanBox Pro runs completely offline inside your local browser memory sandbox, no documents or image files are ever uploaded to any servers. Your private files never leave your device.
Does the scanner support multi-page documents?
Absolutely. You can scan and capture as many pages as you need. They will be added to a list where you can reorder pages and merge them into a single compiled PDF file.
How does the shadow removal and auto-clean filter work?
We use client-side canvas filters to automatically threshold colors, adjust brightness/contrast, and strip shadow gradients, giving you clean black-and-white pages that look like official scans.
