Scan to PDF

Point your camera at any document, receipt, or contract. We automatically enhance the image — boosting contrast and converting to grayscale — so it looks like it came straight out of a real scanner.

How it works

Take a photo of any document — a contract, receipt, form, or note — and this tool will convert it into a clean, professional-looking scanned PDF.

The scanner enhancement converts the image to grayscale and boosts contrast to remove backgrounds and make text sharper, just like a real document scanner.

Everything runs in your browser using PDF-lib. Your images are never uploaded to any server.
