About this app

PDF Document Scanner turns your phone camera into a portable document scanner. Capture any document — receipts, contracts, notes, whiteboards — and export a clean, flat PDF in seconds.

HOW IT WORKS
Point your camera at a document and PDF Document Scanner automatically detects the edges and corrects the perspective, so every page comes out flat and straight. Add as many pages as you want, arrange them, then export the whole document as a PDF.

FEATURES

📷 Live Camera Scanning
Capture documents instantly using your device camera. The live viewfinder shows you exactly what you're scanning so you can frame the shot perfectly before capturing.

📐 Automatic Edge Detection & Perspective Correction
The scanner automatically detects the document edges and applies a perspective transform so the final image looks flat — no more trapezoidal distortion from shooting at an angle.

📄 Multi-Page Documents
Scan multiple pages into a single document. Rearrange or delete individual pages in the page manager before exporting.

📤 PDF Export
Export any document as a standard PDF. Save it directly to your Downloads folder for easy access via the file manager, email, or any other app.

🔍 Pinch-to-Zoom Preview
Review each page at full resolution using pinch-to-zoom before exporting. Zoom in to check sharpness and framing.

🔒 Fully On-Device
All scanning, edge detection, perspective correction, and PDF rendering is done locally on your device using pure Kotlin — no images or documents are ever sent to a server.
