DOCSCAN - Smart PDF Scanner

DOCSCAN is a powerful, smart, and 100% private document scanning application built to turn your Android device into a portable high-definition scanner. Scan documents, receipts, ID cards, notes, invoices, and certificates instantly with automatic edge detection and high-speed image enhancement!

🔥 KEY FEATURES

⚡ REAL-TIME AUTO-CAPTURE & EDGE DETECTION
Powered by OpenCV computer vision, DOCSCAN automatically detects document boundaries and frames paper edges in real time. Simply point your camera over any paper, hold steady, and DOCSCAN auto-captures the shot with zero latency!

🎨 COLOR PRESERVATION & FILTER INTENSITY CONTROL
Unlike basic scanner apps that strip away original pen ink colors, DOCSCAN features an interactive Filter Intensity Control slider. Adjust filter strength from 15% to 100% to preserve original signatures, blue pen ink, red stamps, and highlights while whitening background paper.

📄 HIGH-DEFINITION MULTI-PAGE PDF & ZIP EXPORT
Convert your scans into crisp, multi-page PDFs or high-quality image ZIP packages. Customize page order, re-crop saved pages, rotate images, and share branded PDFs directly via email, WhatsApp, Drive, or print.

📂 LOCAL DOCUMENT CATEGORY ORGANIZATION
Keep your files organized with automatic on-device category filtering:
• 🧾 Receipts & Tax Bills
• 📄 Invoices & Purchase Orders
• 🪪 ID Cards, Passports & Licenses
• 📝 Handwritten Notes & Letters
• 🎓 Certificates & Legal Contracts

💡 SMART CAMERA GUIDANCE & FLASH ASSIST
Never take a bad scan! DOCSCAN provides live directional feedback:
"Move closer", "Move back", "Hold device level", and auto-activates flashlight when low light is detected in dark environments.

🔒 100% PRIVATE ON-DEVICE PROCESSING
Your documents remain 100% safe on your phone. All image processing, edge detection, and PDF generation occur entirely offline on device with zero cloud uploads or data tracking.
