How to scan documents with your phone (no app needed)
You do not need a flatbed scanner — or even a scanner app — to digitize paperwork. A phone camera plus a browser-based tool can produce scans that look flat, straight and print-ready. Here is the whole workflow, from taking the photo to saving a PDF.
Step 1: Take a usable photo
Lay the document on a surface that contrasts with the paper — a dark desk works better than a white tablecloth. Stand directly above it if you can, fit all four corners into the frame, and make sure your own shadow is not falling across the page. Sharpness matters more than angle: a slightly tilted but crisp photo corrects perfectly, while a blurry one cannot be fixed afterwards.
Step 2: Let the scanner find the page
Open the photo in Scandut and the page boundary is detected automatically, with a green outline showing the proposed scan area. If the outline misses a corner — common with cluttered backgrounds — drag that corner into place. A magnifier appears while you drag so you can align it to the exact paper edge.
Step 3: Straighten and enhance
One tap applies perspective correction: the tilted photo is remapped so the page looks scanned head-on. Then pick an enhancement mode. Document mode evens out lighting and darkens text, which is what you want for contracts and forms; Color keeps photos and stamps intact; B&W produces compact grayscale output.
Step 4: Save as PDF or image
Save single pages as PNG or JPG, or scan several pages in a row and download them merged into one PDF. Because Scandut runs entirely in your browser, the photos never leave your device — worth knowing when the paperwork is a contract, an ID or medical records.
