The tool is designed to get that one job done without making you learn a full piece of software first.
Free · No sign-up · PrivateSmart / Local Tools
Turn a document photo into a clean scan.
Rotate it, balance brightness and contrast, choose colour, grayscale or black-and-white, then save a cleaner copy without uploading it.
Tip: grayscale is safest for most documents. Use black & white for clean typed pages, and keep colour when stamps, highlights or coloured annotations matter.
Private by design: all cleanup happens on your device using browser image processing.
Good for
Receipts, forms, printed notes, letters and documents photographed on a phone.
Which scan style?
Grayscale is the best general-purpose choice. Black-and-white works well for clean typed forms. Keep colour when stamps, highlighting or coloured notes are important.
Best results
Take the photo as straight-on as possible with even lighting and the whole page visible. The controls can clean tone and orientation, but very skewed or folded pages may still need manual cropping.
Useful to know
Do the job. Know what to check.
Short, practical guidance for this specific kind of task, without turning a tiny job into a tutorial marathon.
Best results
The cleanest source photo wins.
Check that small text remains readable and that signatures, stamps, highlights or coloured notes have not disappeared.
Photograph the page straight-on with even light and all four edges visible.
In plain English
What matters most.
A document scan is mainly about legibility. Grayscale suits most pages; colour is safer when coloured marks matter.

File size & formats
Big images use more memory than their file size suggests.
What can I use?
JPG, PNG and WebP are the safest choices. Other image formats work when your browser can decode them.
Is there a size limit?
There is no extra OutMonkey upload-size cap in the browser interface. Very high-resolution images can still hit your browser or device memory limit, especially when enlarging them or running local models.
If the file is huge
If an enormous image will not process, use a smaller copy or reduce its pixel dimensions first. Keep the original untouched.
