Understanding mobile scanner

The scanner turns your phone's camera into a document capture device: you frame the page, capture it, and the shots are assembled into a multi-page PDF at full sensor resolution rather than the compressed preview size.

A modern phone camera at 12 MP resolves an A4 page at roughly 300 DPI, which is genuine scanner territory. Technique, not hardware, is what separates a good capture from a bad one.

Camera access is requested by the browser and the frames never leave the device — the PDF is assembled locally and downloaded straight to your storage.

When you would use it

—Scanning a signed contract without access to a scanner.
—Capturing receipts as you collect them during a trip.
—Digitising handwritten notes at the end of a meeting.
—Sending a document from a hotel room with only a phone available.

Practical tips

Hold the phone parallel to the page and fill the frame — that removes most perspective distortion before it happens.
Diffuse daylight beats overhead light; direct lamps create a hotspot in the middle of the page.
Pair the result with OCR PDF to make your scans searchable.

Troubleshooting

The camera does not start: Camera access requires HTTPS and an explicit permission grant. Check the browser's site permissions.
Pages look dark or washed out: Move to indirect natural light and avoid casting your own shadow over the page.
