Scan Document

The difference between a photograph of a page and a scan of it is what happens in the second after the shutter. A photo is taken at an angle, so the rectangle becomes a trapezoid; it includes your desk, your hand and the shadow of your head; and it arrives as a large image file that opens differently on every device. None of that is acceptable on something going to a landlord, a university or an accountant.

Scan Documents corrects all of it. Point the camera at a page and the edges are found automatically, the perspective is squared up, and everything outside the page is cropped away. Capture is at full quality, so small print stays legible rather than dissolving into compression.

Multi-page capture is the part that saves real time. A six-page contract is one session and one PDF, not six photographs for somebody else to reassemble in the right order. Keep going until the document is finished, then save once.

All of this happens on your phone. The pages are not uploaded, the finished PDF is stored on the device alongside the rest of your scan history, and the whole process works with no connection at all — which matters more than it sounds when you are scanning something in a basement office or on a train.

From there the document is ready to use: sign it without printing, merge it with other files into one attachment, or simply share it. The usual reason to open a scanner app is that something needs to go out by email in the next five minutes, and that path is short on purpose.
