Scan documents with your iPhone or iPad — as many pages as you need. Easy Scanner finds the page in front of the camera, captures it as soon as you hold it steady, and straightens it into a clean, readable scan. Put down the next page and it captures again, so a whole stack goes in one page after another. Every scan is kept as a document you can name, reopen and add to whenever you like. Features • No page limit — scan a receipt, a contract, or a whole folder in one go • Automatic capture: the page is taken as soon as it's held still, hands free • Edges found for you, with the perspective straightened out • Adjust the corners by hand whenever a crop needs fixing, while scanning or later • Filters that whiten paper and sharpen text: Enhanced, Grayscale, Black & White, or the untouched photo • Searchable PDFs — text is recognised on your device, so you can search the PDF and copy from it • Copy the text of any page straight from the app • Drag to reorder pages, rotate them, delete them, or change several at once • Export as PDF, sized to your scan or to A4 or US Letter, in three file sizes • Share pages as images or save them to Photos • Import photos you have already taken Everything stays on your device. There is no account to create, nothing to sign in to, and nothing is uploaded.
