FAQ
Frequently Asked Questions
How do I remove shadows and gray background when taking a photo of paper?▼
The B&W Scanner mode applies local adaptive thresholding algorithms that detect illumination variations and convert uneven gray backgrounds into pure white (#FFFFFF), keeping only readable dark characters.
What is the difference between B&W and Document Color modes?▼
B&W mode converts everything to high-contrast monochrome. Document Color mode bleaches the paper background while preserving the authentic hues of blue ink signatures, colored notary stamps, or company logos.
Is it safe to scan sensitive personal documents here?▼
Absolutely. Because of our strict Zero-Server architecture, image adjustments run entirely via your browser's HTML5 Canvas and PDF-Lib APIs. No data is ever transmitted to cloud servers.
