How to scan documents with your phone (no app needed)

Step 1: Take a usable photo

Lay the document on a surface that contrasts with the paper — a dark desk works better than a white tablecloth. Stand directly above it if you can, fit all four corners into the frame, and make sure your own shadow is not falling across the page. Sharpness matters more than angle: a slightly tilted but crisp photo corrects perfectly, while a blurry one cannot be fixed afterwards.

Two habits make a visible difference. First, tap the screen to focus on the text before shooting — phones often focus on the background instead of the page. Second, hold still for a beat after tapping the shutter; most "blurry scans" are actually motion blur from lowering the phone too soon. If your kitchen table and the paper are both white, slide a dark book or folder under the document to give the detector a clean boundary.

Step 2: Let the scanner find the page

Open the photo in Scandut and the page boundary is detected automatically, with an outline showing the proposed scan area. If the outline misses a corner — common with cluttered backgrounds — drag that corner into place. A magnifier appears while you drag so you can align it to the exact paper edge.

If you are scanning several pages, add all the photos at once: each page appears as a card with its own detected area and a confidence badge, so you can review the whole batch, fix only the pages that need it, and then scan everything in one go.

Step 3: Straighten and enhance

One tap applies perspective correction: the tilted photo is remapped so the page looks scanned head-on, at the full resolution of your original photo. Then pick an enhancement mode. Document mode evens out lighting and darkens text, which is what you want for contracts and forms; Color keeps photos and stamps intact; B&W produces compact grayscale output.

Document mode also has a strength setting. The default suits most paperwork; switch to Strong for faint pencil or faded print, or Soft when the default looks too harsh. You can compare against the uncorrected original with one tap, and rotate any page that was shot sideways.

Step 4: Save as PDF or image

Save single pages as PNG or JPG, or scan several pages in a row and download them merged into one PDF — with an option to fit every page onto A4 for printing, and a quality switch for smaller files. Because Scandut runs entirely in your browser, the photos never leave your device — worth knowing when the paperwork is a contract, an ID or medical records.

If you need the words rather than the picture, run text extraction (OCR) on the results screen and download the content as a Text, Word or Excel file. Recognition also runs locally in your browser.

Common problems and quick fixes

The outline grabs the table instead of the page: drag the corners manually, or re-shoot against a higher-contrast background. Text looks gray and thin: use Document mode, and increase strength. The scan looks stretched: one corner was misplaced — even ten pixels off at a corner skews the whole page, so use the magnifier. Colors look dull on a photo-heavy page: switch that page to Color mode; modes are set per page, not per batch.

And the classic one — the file is huge: save as JPG instead of PNG, or choose standard quality for the PDF. A ten-page text document has no business being 50 MB.

FAQ

Do I need to install anything? No — it runs in the browser on any recent phone or computer. Does it work offline? After the page loads, the core scanning features work without a connection, which you can verify in airplane mode. Is there a page limit or watermark? No. Can I scan from the camera directly? Yes — on phones, the camera button shoots straight into the scanner, so the photo never needs to pass through your gallery.
