Сканирование документов

The scanner is in the office, you are sitting at home, and the document has to go digital now. A phone photo is taken quickly but usually looks crooked: the page is distorted because you shot it from an angle, the edges do not run parallel. Document Scanner turns such a photo into a proper scan page, as if it came from a real device.

The trick is corner marking. You set the four corners of the document in the photo - top left, top right, bottom right, bottom left - and the tool computes out the perspective distortion. The skewed quadrilateral becomes a straight rectangle, cleanly cropped and straightened.

Presets tune the result to your case. Colour document keeps the colours, black-and-white text makes plain text crisp and high-contrast, photo is meant for pictures, receipt optimises narrow slips, whiteboard brightens photographed boards, and ID fits card formats. Grayscale and an adjustable threshold help with pale or unevenly lit originals.

Because rarely just one page comes up, there is batch scanning: photograph several pages one after another, deskew each individually and export them together at the end as a multi-page PDF. Alternatively you save as PNG or JPG when you only need a single image.

The demanding perspective deskewing is handled by the server, because it needs computing power that would be sluggish on a phone. The tool is set up as a Plus feature. You keep control over your images and end up with straight, readable pages instead of crooked phone photos.
