What is Document scanner app?
A document scanner app uses a smartphone camera to photograph paper documents and convert them into digital files — typically PDFs. The app uses image processing to detect the document edges, correct perspective distortion (so a photo taken at an angle looks flat and straight), and enhance contrast for readable text. Advanced scanner apps also include OCR to make the resulting file searchable. PDF Scanner is a free document scanner app for Android that combines all these features in a single, lightweight app.
