LensUp Scanner is a free, browser-based document scanner that turns phone photos into clean, printable PDFs and includes ID-card copy and PDF tools. To scan, take a photo of a page with your phone, then crop it, correct the perspective and remove shadows so the page comes out flat and even. You can scan several pages in a row and save them together as one multi-page PDF. The ID-card copy tool places the front and back of a card on a single printable sheet. For documents you already have, there’s a PDF editor along with tools to merge several PDFs into one and to add a signature. Every tool is free, and files process on your device.
