About Document Scanner
Document Scanner replaces the flatbed scanner with your phone. Point the camera at any document — an ID card, a certificate, a receipt, handwritten notes — and the app captures it with autofocus lock for maximum sharpness. Adjust the corners to crop precisely, pick the B&W document filter for that clean scanned look, and save or share a high-resolution PDF. Students scanning assignments, job seekers digitising certificates, shopkeepers archiving receipts: everyone gets professional scans without any hardware.
Every scan is enhanced on-device. The adaptive black-and-white filter handles shadows and uneven lighting, so text stays readable even from imperfect photos. Multi-page documents are supported — keep adding pages, then export everything as a single PDF. All processing happens on your phone; your documents are never uploaded anywhere.
Key Features
Smart Camera Capture
Autofocus lock before every shot, document guide overlay, and flash control for sharp captures in any light.
Corner Crop
Drag the corner handles to fit the document edges exactly — no background clutter in your scans.
Document Filters
B&W Doc, Grayscale and Enhanced filters. Adaptive threshold keeps text crisp even with shadows.
High-Res PDF Export
Export sharp PDFs at double resolution — perfect for printing or official submissions.
Import from Gallery
Already have a photo? Import it from the gallery and turn it into a clean scanned document.
OCR Text Scanner
Extract text from any image with built-in OCR — copy, share or save the recognised text.
Pro Tips
For sharpest scans
Take the photo with your phone's camera app, then use Import from Gallery — this gives the cleanest source image.
Hold steady
When using the in-app camera, wait for the "Focusing, hold steady..." message before the shot is taken.
Good lighting matters
Natural daylight gives the best results. Avoid harsh shadows across the document.
