Scanning a document is simple once you know a few basics; this guide shows you how.
You have a stack of papers that need to become digital files, and you want to know how to use a scanner to get it done without a headache. Whether you have a dedicated flatbed scanner or just your smartphone, the core process is the same: place the document correctly, pick your source, start the scan, and save it as a PDF. This guide walks through each method with exact steps that work today.
Getting Your Scanner Ready on Windows
Most modern scanners work with Windows the moment you plug them in. Microsoft’s current guidance says that for a standard USB or wireless connection, you simply connect the scanner to your computer and it’s ready for use. For Windows 11, if it doesn’t appear automatically, you’ll find it in Settings > Bluetooth & devices > Printers & scanners. There, use the Add device button next to Add printer or scanner.
Once Windows recognizes the hardware, open the built-in Scan app from your Start menu. The key step is confirming you have the right Scanner chosen at the top of the app window. If you have more than one device, the wrong one being selected is a common cause of failure.
Choosing the Right Scan Source
Selecting the correct Source is the single most common mistake people make. The Scan app gives you three choices that must match where you physically placed the paper:
- Flatbed – for a single page placed face down on the glass.
- Feeder – for a stack of pages loaded into the automatic document feeder.
- Auto-configured – lets the scanner detect the input type itself.
If you put paper in the feeder but leave the source on Flatbed, your scan will fail or capture the wrong thing. Placement orientation also matters—your scanner’s own documentation is the authority on whether it wants pages face up or face down. Double-sided pages require a scanner that specifically supports duplex scanning; otherwise, you’ll flip them manually for a second pass.
How to Scan With Your Phone (iPhone and Android)
When a dedicated scanner isn’t nearby, your phone does the job with zero extra hardware. On an iPhone or iPad, Apple’s built-in method lives in the Notes app. Open a note, tap the camera control at the bottom, and select Scan Documents. Hold the device over the page; in Auto mode it captures on its own, or you can press the shutter button manually. Once captured, drag the corners to fit the page and tap Keep Scan.
Cropping out the background in the preview step gives you a cleaner file. Android users on most current Samsung, Pixel, and other handsets have a similar scanning mode built into their default camera app, often labeled Document, which automatically detects page edges.
What to Do Before You Scan
A few minutes of preparation separates a clean scan from a frustrating one. Straighten folded corners and repair torn pages with tape on the back side so the front reads cleanly.
When you save, choose PDF for almost everything. The one exception is a single photo you want to edit later, where JPEG or PNG makes sense; the Windows Scan app lets you pick this file type in its settings. If you need to search or copy text later, enable OCR (optical character recognition) at scan time. This makes the text machine-readable instead of a static image. Resolution matters, too—
Finally, the Windows Camera app also has a Document mode that works like a phone scanner—but only if your webcam supports it. If you don’t see the option, that camera lacks the feature.
The right scanner makes this entire process faster on a regular basis. For the models that balance speed, document feeders, and OCR quality, our roundup of the best document scanners for home offices breaks down the top picks by volume and budget.
Securing Your Scanned Files
Sensitive documents deserve care after scanning. The State Department recommends emailing scans to a trusted account you control or saving them to secure cloud storage rather than leaving them on a shared device. For physical security, shred the paper original once you’ve verified the digital copy is readable and backed up.
