Scan to PDF with your camera — no app needed
Scan to PDF from a photo or straight from your camera. Each page is found, straightened and evened out so it reads like a flatbed scan, then saved as one PDF — on your own device.
Where is this PDF going?
Fit Meter
Settings appear once you add a photo.
Color, grayscale and black & white even out shadows so the paper reads as white. Black & white makes the smallest file — ideal for text.
Still going. Your own device is doing this, so a long scan or a big batch takes as long as it takes — and none of it is being uploaded.

Every request this page makes is listed as it happens. You’ll see our own code loading, and for some formats a codec engine, but never your file going out.

How to scan to PDF with your phone
-
Add your photos
Press Use your camera and photograph each page, or choose photos you already took. Lay the page on something darker than the paper and fill most of the frame.
-
Check the settings
Each page is found, straightened and cleaned up. Tap Adjust on any page to move its corners, or turn it the right way up.
-
Save the result
Pick color, grayscale or black & white, then save one PDF with every page in order.
Why it doesn’t upload
What people scan is exactly what they should not hand to a stranger: ID cards, bank letters, signed forms, medical notes. Scanning apps upload to their cloud; this one never sends a photo anywhere — the camera feed and every page stay on your device.
Check it in your browser’s Network tabWorth knowing
- The page is found by its contrast with what is behind it. A white page on a white desk may not be detected — use Adjust to set the corners, or lay it on something darker.
- A page curled like an open book is straightened as a flat quadrilateral, so the curve near the spine stays.
- The text is not made searchable: that needs OCR, which is coming to the site but is not live yet.
- The camera needs a secure page and your permission; it works in current Chrome, Safari, Firefox and Edge on phones and laptops.
Under the hood
What happens to your file
Each photo is searched for the page: its edges and corners are found, the page is straightened with a perspective correction, and uneven light is evened out. Black-and-white pages are stored as 1-bit images, a fraction of the size of a color photo, and every page is placed in a PDF of the size you pick.

Questions
How do I scan to PDF on my phone without an app?
Open this page, press Use your camera and photograph each page. The pages are straightened and cleaned up here, in your browser, and saved as one PDF — nothing to install and nothing uploaded.
Can I scan to PDF with my laptop webcam?
Yes. The same button uses a laptop or desktop webcam. Hold the page flat and fill the frame; webcams are lower resolution than phones, so black & white usually gives the most legible result.
Why does my scan have shadows or a gray background?
It shouldn’t with Color, Grayscale or Black & white: the lighting across the page is measured and divided out, so the paper reads as white. Photo as taken keeps the photo exactly as it was.
Which look makes the smallest PDF?
Black & white, by a long way: each page is stored at one bit per pixel, usually 30–100 KB, where a color page is several hundred. Use it for text; keep color for anything with photos, stamps or highlighting.
Are my photos uploaded to scan them?
No. The camera feed and every photo are processed inside this browser tab. You can switch off Wi-Fi once the page has loaded and it keeps working.
Can I scan several pages into one PDF?
Yes — add as many as you need, by camera or from your photos, and put them in order with the arrows. They are saved together as one PDF.
