Document Scanner Online — Free, No Signup
Turn a photo of a document into something that looks scanned. It flattens the lighting, lifts the contrast, and pushes the page towards clean white with dark text — the difference between a snapshot and a document someone will accept.
How to do it
- Photograph the page, then drop the photo onto the upload box.
- Let the scanner find the page edges and correct the perspective.
- Pick black and white for text, or greyscale to keep photographs on the page readable.
- Download the cleaned-up scan.
Why a photo of a page looks wrong
Three things separate a phone photo from a scan. Lighting is uneven, so one side of the page is bright and the other is in shadow. The paper is grey rather than white, because the camera exposed for the whole scene and paper is the brightest thing in it. And the text is grey rather than black for the same reason. A flatbed scanner sidesteps all three by lighting the page evenly from a fixed distance. This tool corrects for them afterwards instead, which is not quite as good but is available on any device you already have.
What the processing does
The image is converted to a contrast-normalised form where local brightness variation is removed, so shadow across one half of the page stops mattering. Then the tonal range is stretched so paper goes to near-white and ink goes to near-black. The result is a high-contrast page that reads cleanly on screen, prints properly, and compresses to a fraction of the original photo's size, because a mostly-white image with black text is exactly what compression handles best.
Take a better photo first
The processing can fix lighting; it cannot fix geometry or focus. Hold the camera parallel to the page rather than at an angle, or the text on the far side stays smaller and harder to read. Get the whole page in frame with a small margin. Avoid casting your own shadow across the middle, which is the single most common problem — move so the light comes from behind you at an angle rather than over your shoulder. Tap to focus on the text before shooting; a soft photo cannot be sharpened into a legible one.
What it does not do
There is no text recognition. You get a clean image of the page, not a searchable or editable document, and nothing extracts the words into a file you can copy from. There is also no automatic perspective correction, so a photo taken at an angle stays at that angle — crop and straighten it beforehand if that matters. And it produces a single image per run rather than assembling a multi-page PDF; for multiple pages, process each and combine them in whatever tool you use for PDFs.
Limits
Input up to 5 MB, with the long edge capped at 2000 pixels — comfortably enough for A4 text to stay legible. Everything runs in your browser, which matters more here than for most tools: contracts, medical letters, bank statements, and identity documents are exactly the things people scan, and none of them are uploaded anywhere.
Frequently asked questions
Does it convert the document to text?
No. There is no text recognition. You get a clean image of the page, not a searchable or editable document.
Will it straighten a photo taken at an angle?
No. There is no automatic perspective correction. Crop and straighten before processing if the angle matters.
Can I make a multi-page PDF?
Not here. It produces one image per run. Process each page, then combine them in a PDF tool.
Why is my scan still grey?
Usually a very underexposed source or a heavy shadow across the page. Retake the photo with light coming from behind you at an angle.
Is my document uploaded?
No. Everything runs in your browser, which is the point for contracts, medical letters, bank statements, and identity documents.
What resolution do I get?
The long edge is capped at 2000 pixels, which keeps A4 text comfortably legible on screen and in print.
