LensUp Scanner

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; its free tools process your files on your device. 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. Everything opens in the browser, and the site is available in 20 languages.
