How to scan a document to PDF on your phone

  1. Tap Scan with camera and take a photo of the page (or choose photos you already have)
  2. Check the 4 corners: they are found for you; drag a handle if one is off
  3. Tap Scan next page for more pages, or Done
  4. Pick a look: Magic colour, Original, Grey or Black & white
  5. Tap Download PDF, or Share PDF straight to WhatsApp or Gmail

Why scans look better than photos

A photo of paper is never flat: it is taken at an angle, the light is uneven and your hand casts a shadow. The scanner fixes all three. It finds the edges of the page and straightens it into a rectangle, then measures the light across the paper and evens it out, so the paper turns white and the writing stays sharp.

  • Magic colour keeps stamps, signatures and coloured pens. Best for certificates and forms.
  • Black & white gives the crispest text and the smallest file. Best for notes and printed pages.
  • Grey sits in between; Original keeps the photo as it was, only straightened.

Frequently asked questions

Quick answers about the scan to pdf tool.

Is my document uploaded?

No. The page is found, straightened and cleaned on your phone, and the PDF is made there too. ID cards, certificates and bills never leave your device.

How do I get the best scan?

Put the paper on a darker table, hold the phone straight above it, and use daylight or a bright room. Keep the whole page in the photo with a little table around it.

It did not find the corners. What now?

Drag the 4 round handles onto the corners of the page. A magnifier shows exactly where you are while you drag. Whole photo uses the full picture.

Can I scan many pages into one PDF?

Yes. After each page tap Scan next page. Change the order with the arrows and turn pages with ⟳. All pages go into one PDF.

How do I make the PDF small for an upload?

Choose File size: Small and the Black & white look. A page of text is then usually around 100–200 KB. Still too big? Use Compress PDF.

Is it free? Is there a watermark?

Free, with no watermark, no sign-up and no page limit.
