Scan a document — from a photo of it
Straighten a page shot at an angle, kill the shadow across it, and save several pages as one PDF. None of it leaves your device.
A photo of a page is not a scan. It is shot at an angle, so the page is a trapezoid, and it is lit by whatever was in the room, so one side is bright and the other sits in the shadow of your own head. Increasing the contrast never fixes the second problem — it just turns the dark half solid black. This tool maps the four corners you place back onto a rectangle, then decides light-or-dark for every pixel against its own neighbourhood rather than one cutoff for the whole page, which is the only thing that survives uneven lighting.
Is my document uploaded?
No. The photo is opened, straightened and cleaned up entirely in your browser, and the PDF is written there too. The uploads counter in the top bar stays at 0. That matters here because the things people photograph are contracts, passports, tenancy agreements and medical forms.
Why doesn't increasing the contrast work?
Because the problem is not global. A photographed page is lit unevenly — bright on one side, shadowed on the other — so any single brightness cutoff turns the dark half solid black while the bright half washes out. This tool compares every pixel with the average of its own small neighbourhood instead, so a shadow across the page stops mattering.
Does it find the corners automatically?
No, deliberately. Corner detection fails on busy backgrounds and low contrast, and when it fails it quietly crops the edge off a document — which on a contract is the signature. The four handles start as a rectangle and take about three seconds to place, and the preview shows exactly what you are getting before you commit.
Can I scan more than one page?
Yes. Each photo you add becomes a page, and they come out as a single PDF in the order you added them. A contract is not one page.
What happens to the EXIF data?
It does not survive. The output is built from a fresh bitmap, so the GPS coordinates and camera details from the original photo are not carried into the scan.
Do I need an account?
No. No signup, no watermark, and no limit on pages.
Get the text out of it
A scan has no text layer, so searching it does nothing until something reads the pixels. Image to text runs an OCR engine on your device — and a straightened, evenly-lit page is dramatically easier for it to read than the original photo was.
Black something out, or sign it
Redact a PDF destroys the text underneath rather than covering it, and Sign a PDF stamps a signature on the page. Neither uploads the file.
Split it or merge it
PDF Tools will merge this with another document, pull pages out, rotate or compress it.
