How to use the Scan to PDF tool

  1. Tap the camera button and photograph the first page.
  2. Repeat for each page; they are added to the list in order.
  3. Reorder or remove any page with the arrows and the remove button.
  4. Choose the clean-up: black and white for text, greyscale for mixed pages.
  5. Press Create PDF and download it.

No app, and what that gets you

The camera button is an ordinary file input that asks your phone to open the camera. Your phone's own camera app takes the photograph, hands the image to this page, and the page does the rest. That is the whole trick, and it is why nothing has to be installed.

The practical difference against a scanner app is privacy and permissions. There is no app on your phone with access to your camera roll, no account, no cloud folder, no subscription, and no upload. The pictures go from the camera into this tab and out as a PDF.

It works on a computer too, where the same button simply lets you choose photographs you already have - useful when someone has emailed you pictures of pages and you need them as one document.

The clean-up, and which to choose

A photograph of a page is not a scan. It has uneven lighting, a grey cast where a flatbed would give white, and a shadow where your hand or phone blocked the light. Left alone it looks like what it is, and it makes a large, murky PDF.

Black and white uses a local threshold: for each pixel it compares the brightness with the average of the area around it, rather than against one fixed level. That is why a page that is bright on one side and shadowed on the other still comes out as clean black text on white. For printed text it is both the most readable option and by far the smallest file.

Greyscale keeps the shades and lifts the contrast. Use it for pages with photographs, diagrams, stamps or shading, where a hard black-and-white threshold would lose detail. Colour keeps everything and only adjusts the contrast, which suits ID cards, certificates and anything where the colour is the point.

Page order, page size and margins

Pages appear in the order you took them and can be moved with the arrows or removed individually, which matters because the one page everyone re-takes is the one that came out blurred.

A4 or Letter puts each photograph on standard paper, centred, which is what offices, portals and print shops expect. "Fit the page to the image" makes each PDF page exactly the shape of the photograph instead, which suits receipts and anything not on a standard sheet.

A small margin, six millimetres by default, keeps the text away from the very edge of the paper so nothing is clipped by a printer.

What it does not do

It does not find the edges of the paper and straighten the page. Commercial scanner apps detect the four corners of a sheet and correct the perspective, and that is a genuinely difficult job to do reliably; a bad guess produces a worse result than no guess at all.

So frame the page squarely, fill the viewfinder with it, and keep the camera parallel to the paper. If there is a border of desk around the page, Crop PDF will trim it afterwards in a few seconds.

It also does not read the text. If you need the document to be searchable, run the finished PDF through OCR PDF, which adds an invisible text layer.

Photographs carry more than you think

A phone photograph normally includes EXIF data: the date and time, the camera model, the settings, and on most phones the exact GPS position where it was taken. Emailing a photographed document to a stranger can quietly tell them where you live.

Because every photograph is drawn on a canvas and re-encoded for the PDF, none of that survives. What goes into the PDF is pixels only.

The pictures are also rotated correctly on the way in. A phone usually stores a photograph in the sensor's orientation plus a flag saying which way up it was, and this page honours that flag so your pages are not sideways.

Nothing is uploaded

Files are not uploaded - everything happens in your browser. The photographs are read locally, cleaned up locally and assembled into a PDF in memory on your device.

That is particularly worth knowing for this tool, because what people photograph is identity documents, bank paperwork, medical letters and signed agreements.

Images are processed one at a time with a progress bar, and each page is released before the next is handled, so a forty-page scan does not exhaust a phone's memory.

Frequently asked questions

How do I scan a document with my phone?

Tap the camera button here, photograph each page, choose the clean-up and press Create PDF. No app is needed.

Which clean-up should I use?

Black and white for ordinary printed text - it is the most readable and the smallest. Greyscale for pages with photographs or shading, colour when the colour matters.

Does it straighten the page automatically?

No. It cleans up the picture but does not detect the paper edges. Frame the page squarely, and use Crop PDF afterwards if you need to trim.

Is the location data from my photos included?

No. Re-encoding removes EXIF and GPS data, so the PDF holds pixels only.

Can I reorder the pages?

Yes. Use the arrows next to each photograph before creating the PDF.

Will the PDF be searchable?

Not on its own - it contains pictures. Run the result through OCR PDF to add a searchable text layer.

Are my photographs uploaded?

No. Everything happens in this browser tab, with no account and no server.
