No app to install. No account to make.
You need to scan a document — a receipt, a form, a letter — and send it as a PDF. But you don't want to install another scanner app, deal with watermarks, sign up for a trial, or pay $4.99 a month for what is essentially one button press. Your phone already has a camera and a browser. That should be enough.
It is. Open PDFThis in any phone browser, tap Take a Photo, point your camera at the document, and the page is detected and turned into a clean PDF in about five seconds. The result looks like a real scan — edges cropped, page deskewed, background removed, text crisp. Free, no watermark, no signup.
