How to Scan a Document: Printer, Phone or Browser

November 4, 2026

To scan a document, you need something that can take an image of the page: a scanner or all-in-one printer connected to your computer, your phone’s camera with a scanner app, or a webcam and a browser. Place the page, capture it, then save it as a PDF or JPG. For most everyday paperwork, your phone is the quickest way to scan, and the result is good enough to email, upload or print.

Below are the three ways to scan, compared, with short steps for each and links to the detailed guides.

The three ways to scan, compared

Each method suits a different job. The table sums up the trade-offs.

	Scanner or printer	Phone	Browser and webcam
What you need	A scanner or all-in-one printer, plus a computer	Your phone	A laptop or desktop with a camera
Time for one page	Longer: warm-up, preview, scan pass	A few seconds	A few seconds
Multi-page documents	Easy with a document feeder	Easy, one page after another	Possible, one page at a time
Image quality	Best: flat, even light, fixed resolution	Very good with a scanner app	Fine for text, limited by the webcam
Best for	Photos, fragile or bound originals, archives	Forms, letters, receipts, IDs	Occasional pages when you’re at the computer

A decision chart: use a scanner if you have one and the original is a photo or fragile, otherwise use your phone, or a webcam in the browser — Pick the method by what you have and what you're scanning.

How to scan with a printer or scanner

Most all-in-one printers can scan, as long as the printer is connected to your computer by USB or the same Wi-Fi network.

On Windows 11

Check that Windows sees the scanner in Settings > Bluetooth & devices > Printers & scanners. Windows usually adds it automatically.
Open the Windows Scan app (search for it in Start; if it isn’t there, install it free from the Microsoft Store).
Put the page face down on the glass, or in the document feeder.
Choose the scanner, the source (flatbed or feeder) and the file type, then click Preview to check the page.
Click Scan. Unless you choose another folder, the file goes to Pictures > Scans.

Microsoft’s guide covers adding a scanner by hand if Windows doesn’t find it.

On a Mac

Open Image Capture from Applications, or open System Settings > Printers & Scanners, select the printer and click Open Scanner.
Put the page on the glass.
Click Show Details to pick the file type (PDF or JPEG), the resolution and where to save it.
Click Scan.

Many printer makers also have their own scanning app with more settings, but the built-in tools are enough for documents. For the settings themselves, 300 DPI suits almost any document; see the best DPI for scanning documents for when to go higher.

How to scan a document with your phone

Your phone is a scanner as long as you use a scanning tool rather than the plain camera. The scanner finds the page’s edges, cuts away the table, corrects the angle and makes the paper look white.

Lay the page flat on a surface darker than the paper, in even light.
Open a scanner: on iPhone, Notes (paper clip > Scan Documents) or Files; on Android, Google Drive (the camera button); or a scanner app.
Hold the phone over the page with all four corners in view, and hold still. Most scanners capture by themselves.
Check the page. Fix the corners or rotate it if needed, and add more pages.
Save it as a PDF, or share it straight from the scanner.

A page photographed at an angle on a wooden desk, beside the same page cut out, straightened and cleaned up — A phone scan: the page is found on the desk, straightened and cleaned up.

In Copier, the page’s outline appears live as you point at it, and with Auto on it takes the page once you’ve held still for about a second. Each page is straightened, including curled ones, and cleaned up on the phone. Copier is free for scanning and sharing pages as JPG, and PDF export is part of a one-time Copier Pro purchase. Nothing is uploaded and there’s no account.

How to scan in a browser

If you’re at a computer with no scanner, a browser-based scanner can use its webcam. Copier in your browser works this way, processing the page on your computer without uploading it. Hold the page up to the camera, or lay it flat and tilt the laptop screen down, and keep it still. A webcam has fewer pixels than a phone, so it’s best for typed text rather than small print. Scanning documents with a webcam has tips for getting a sharp page.

Tips for any method

Use PDF for documents and anything with more than one page, JPG for a single page you’ll view as a picture.
Scan in color only when the color matters, like stamps, signatures in blue ink or photos. Black and white keeps text documents small.
Name the file before you send it. “2026-11-04 lease renewal.pdf” is easier to find later than “Scan 14”.
Check every page before sending. A cut-off line or a page out of order is easier to fix now than after the form is submitted.

Questions

How do I scan a document to my computer?

Put the page on your scanner or printer's glass, then on Windows open the Windows Scan app and click Scan, or on a Mac open Image Capture, pick the scanner and click Scan. Without a scanner, scan it with your phone and send it to the computer.

How do I scan a document with my phone?

On iPhone, open Notes, tap the paper clip and choose Scan Documents. On Android, open Google Drive and tap the camera button. Hold the phone over the page, let it capture, then save as a PDF.

Is a phone scan as good as a scanner?

For letters, forms and receipts, yes. A recent phone has enough resolution and a scanner app straightens and cleans the page. A flatbed is still better for photos, fragile originals and anything you want at very high resolution.

What format should I scan a document in?

PDF for documents, especially with more than one page, and JPG for single pages you'll view or post as an image. Use color only when the color matters.
