How to scan a document with your phone and get a clean PDF
We built Scan to PDF for the moments when there is no scanner nearby: a signed form that has to go out today, a receipt for an expense claim, or a few pages of notes. On a phone, the tool opens your camera so you can photograph each page in turn; on a desktop, you pick existing image files. Every page is placed on an A4 sheet and exported together as a single PDF, and because it all runs in your browser, the photos never leave your device.
Document mode is the switch we recommend for text pages. It raises contrast and converts the image to grayscale, which turns a grey, slightly shadowed photo into crisp dark text on a light background and usually makes the file smaller. Leave it off for color documents, photos or anything where a stamp or signature color matters.
To be straightforward: the tool does not detect or crop page edges automatically. The best results come from shooting straight from above, in good even light, with the paper on a dark table so the page stands out, and filling the frame with the page. The scan also contains no text layer; if you need to search or copy text, run the finished PDF through our OCR tool afterwards to make it searchable.
Our take
We use Scan to PDF mostly for paperwork that has to go out quickly: a signed contract page, a delivery note or a stack of receipts at the end of the month, all combined into a single file.
Our routine is simple: paper on a dark desk, phone held flat above it, document mode on for text, and one quick check of each photo before adding the next. That removes most of the blur and shadows that make phone scans look amateur.
It is not a replacement for a flatbed scanner when you need archival quality or automatic edge cropping. For long documents we would also run OCR afterwards, so the PDF can be searched later.
