LensUp - Free online document scanner that turns photos into clean PDFs
LensUp is a free online document scanner that runs entirely in your browser. Photograph any paper with your phone and turn it into a clean, printable scanned PDF: crop, perspective correction, de-shadow, erase handwriting from worksheets, compress to an exact size like 200 KB for form uploads, ID-card front-and-back layout, and searchable PDFs with built-in OCR. No app to install, no sign-up, no watermark - and your files are never uploaded to a server. Works on phones, tablets and desktops in 14 languages.
