Runs in your browser — your file never leaves your device.

Turn photos of paper into a clean, flat-looking PDF, on your device. Scan to PDF takes pictures from your camera or your files, crops each one to the page edges so it fills the sheet, and applies a scan style so a phone snap of a receipt looks like it came off a scanner. Choose colour, grayscale or high-contrast black and white, set the output quality and page size, and nudge brightness and contrast until the text is clear. Nothing is uploaded.

How to use Scan to PDF

Click "Use camera" to shoot pages as you go, or add photos you already have. Each picture becomes one page.
Pick a scan style. Colour keeps what was on the page, Grayscale gives a clean photocopier look, and B & W pushes for the smallest, highest-contrast file.
Set quality — High (300 DPI) is the recommended default. Leave "Crop to the page" ticked so the desk around a bright sheet is trimmed away, but note it is skipped when no clear edge is found.
Adjust brightness and contrast if the text is faint or the paper is grey. The preview updates as you move the sliders.
Choose a page size, then click "Save as PDF" and download.

Who it is for

Scan to PDF is for turning paper into a document with a phone instead of a scanner: a receipt for expenses, a signed form that has to be returned, a letter to file, or a page of a book needed for a quotation. It is also used to make a photographed document look deliberate rather than like a phone snap.

How it works

Photos from the camera or the file picker become pages, each fitted to a chosen paper size.
The scan style is applied per page — Colour keeps the original, Grayscale removes the colour cast from indoor light, and black and white pushes contrast hard so text is black and the paper white.
Brightness and contrast adjust the rendered result before the pages are written into the PDF.

What it cannot do

There is no perspective correction. Cropping trims to a bright page edge when it can find one clearly, but a page photographed at an angle stays skewed.
Auto-crop is skipped when no clear edge is found, which is what happens with a dark desk, low light or a page filling the frame.
Black and white can lose a coloured stamp or a pale-blue signature.
Everything is processed on the device, so a very long scan is limited by the phone's memory.

Frequently asked questions

Are my photos uploaded?

No. The pictures are read, straightened and written into a PDF entirely in your browser, so you can photograph a passport, a bank letter or a medical form without it leaving your phone.

Why is my scan a bit lopsided or not quite square?

"Crop to the page" trims to a bright page edge when it can find one clearly, and leaves the photo alone when it cannot. It does not correct perspective, so a page shot at an angle stays slightly skewed — reshooting flat, in good light and filling most of the frame is faster than fighting it.

What is the difference between the three scan styles?

Colour keeps the document as it looked. Grayscale converts to clean grey, which removes colour cast from indoor lighting and usually reads better. B&W pushes contrast hard so text is black and paper is white, which looks sharpest and compresses smallest — but it can lose a coloured stamp or a signature in pale blue.

Which quality should I choose?

High (300 DPI) for anything you might print or read on a screen later, which is most documents. Balanced (200 DPI) is fine for a form you will only read. Lossless is for archival copies where every pixel matters. Small file (150 DPI) is for something you only need to preview.

My landscape photo became a portrait page.

That is what "Force portrait pages" does, and it is off by default so a landscape photo normally keeps a landscape page. If your pages are mixed and you want them all upright, turn it on and check the preview.
