PDF Scanner turns photos of paper documents into a clean, straight PDF — like a scanner app, right in your browser. Take a photo or choose existing ones, drag the corners to the edges of the page, pick a filter to make text clear, and save all pages as one PDF.

How to scan a document to PDF

  1. Tap "Take photo" (on a phone) or "Choose photos".

Frequently asked questions

Which filter is best?

Black & white gives the clearest text for forms and letters and removes shadows. Magic colour brightens the paper but keeps stamps, signatures and colour. Use Original for photos.

Can I scan many pages into one PDF?

Yes. Keep adding photos — each one becomes a page. Use the arrows to change the order.

Tips for a good scan?

Use daylight or a bright room, place the paper on a dark surface, hold the phone straight above it and avoid your own shadow.

Is it really free? Do you add a watermark?

Yes, it is completely free with no sign-up, no watermark and no daily limits. The site is supported by a few non-intrusive ads.
