Scan to PDF
Turn your phone camera into a document scanner — capture pages, enhance them for readability, and save one clean PDF. Everything runs on your device; nothing is uploaded.
Scan a document
Full-screen camera that finds the edges of the page, straightens it, and cuts away whatever it is lying on.
Captured pages show here — reorder, turn or delete them before you save.
Scanned entirely on your device. The camera stream and every page stay in your browser — nothing is uploaded. Your ID, your signature, your receipts never touch a server.

How it works

Each page is enhanced for readability and lined up in order — reorder or delete any before you save.
- 3
Save one clean multi-page PDF. Everything happens on your device; nothing is uploaded.
Frequently asked questions
Do my scans get uploaded?
No. The camera stream and every captured page stay in your browser — an ID, a signed contract or a receipt never touches a server. The PDF is assembled on your device.
What does “Enhance for readability” do?
It applies a light grayscale and contrast lift so a photographed page reads like a proper scan — paper brightens toward white, ink darkens. It’s deliberately gentle so faint text isn’t lost; turn it off for color documents or photos.
Can I use it on a laptop without a camera?
Yes — use “Add photos” to pick images you already have. It builds the same clean PDF from them.
Is there a page limit or a watermark?
No limit, no watermark, no signup — it runs on your device, so it stays free and unlimited.

Changes to this tool specifically, not the site.

Crop a scan without opening the preview first
Cropping lived only inside Preview, and not everyone opens Preview — plenty of people go straight from the shutter to Save PDF. A page whose edges could not be found is still the whole picture, desk and all, so that page went into the PDF uncropped and nothing had said so. The page list now marks those pages, says how many there are, and has a Crop button on every row that opens straight onto the corner handles. The scanner says it at the moment of the shot too.
- Improved
Undo a crop and place the corners again
Cropping by hand is a judgement, and until now it was one you could not revise — a corner dropped in the wrong place meant scanning the document again. A cropped page now has an Undo crop button in Preview, which puts the whole picture back so you can drag the corners where you actually wanted them. It always returns to the original capture, not to the attempt before, because placing the corners again is the point. It is only offered on a page that has been cropped, and it disappears once there is nothing left to undo.
- Fixed
Colour scans come out the right colour
Scanning something lit by a screen or a warm lamp came back tinted — a bluish page turned cyan. The cleanup was brightening all three colour channels by the same amount, and that cannot remove a colour cast: it amplifies one. A photo of a screen measured 178 red, 190 green, 206 blue; multiplying all three to bring the page up to white clipped green and blue at the top of the scale and left red trailing, which is a cyan page. Each channel is now balanced against its own background, so whatever the paper was lit by, the three come up to white together and the cast goes with them. Ink and stamps keep their own colour. And the Crop button in Preview now explains itself: when the edges were not found, the page says so and offers cropping as the next step rather than as an unlabelled option.
