Scan a Document in Windows 10: Built-In Tools

Updated · Standard formula, shown below

You can scan a document in Windows 10 using the built-in Windows Scan app, the Windows Fax and Scan utility, or the scanning software that came with your printer. No extra downloads are needed for most scanners and all-in-one printers — just connect the device, open the right tool, and press the scan button.

What You Need Before Scanning

To scan a document in Windows 10, your scanner or all-in-one printer must be connected to your PC and turned on. The connection can be USB, Wi-Fi, or Ethernet. Windows 10 automatically installs basic drivers for most modern scanners, but if your device is older, you may need to install the manufacturer’s driver software from its support website.

Check that the scanner is recognized by Windows:

  • Open Settings > Devices > Printers & scanners.
  • Look for your device in the list. If it appears, it is ready to use.
  • If it does not appear, try reconnecting the cable or restarting the device, then click Add a printer or scanner.

Most flatbed scanners have a glass surface where you place the document face-down. Sheet-fed scanners take a stack of pages from a tray. Knowing which type you have helps you position the document correctly.

Using the Windows Scan App

Windows Scan is the modern app included with Windows 10 (version 1803 and later). It is the easiest way to scan because it has a clean interface and saves files automatically.

  1. Click the Start button and type Scan.
  2. Open the Windows Scan app from the search results.
  3. If you have more than one scanner, select the one you want from the Scanner drop-down at the top.
  4. Choose the scan type: Photo or Document. Document mode applies contrast and sharpening to make text clearer.
  5. Select the file type: PDF for multi-page documents, or JPG/PNG for single images.
  6. Click the Scan button at the bottom.
  7. After the scan finishes, a preview appears. You can rotate, crop, or delete pages.
  8. Click Save to choose a destination folder and file name.

The app saves files to your Scans folder inside Pictures by default. You can change this on the save screen.

Using Windows Fax and Scan

Windows Fax and Scan is an older desktop program that has been part of Windows for many versions. It still works in Windows 10 and offers more control over resolution and color settings.

  1. Press Windows Key + S, type Windows Fax and Scan, and open it.
  2. Click New Scan in the toolbar.
  3. In the dialog box, choose your scanner if it is not already selected.
  4. Adjust the Profile (Photo or Document), Color format, File type, Resolution (DPI), and Brightness/Contrast.
  5. Click Preview to see how the scan will look.
  6. Click Scan to produce the final image.
  7. Go to File > Save As to save the file.

This tool is especially useful if you need a specific DPI (dots per inch) for printing or archiving. For example, 300 DPI is common for documents that will be OCR’d, while 150 DPI is enough for simple viewing.

Using Your Printer’s Software

Most printer manufacturers include their own scanning utility. These often give you extra features like automatic document feeder (ADF) scanning, multi-page PDF creation, and direct email or cloud upload.

To find it:

  • Look for the manufacturer’s app in the Start menu (e.g., HP, Canon, Epson, Brother).
  • If you don’t see it, check the manufacturer’s website for the full driver package.
  • Open the app and look for a Scan or Scan to PC section.

These programs often let you choose a scan profile (like “Document” or “Photo”) and a destination folder. Some also have an OCR (Optical Character Recognition) feature that converts the scanned image into editable text, but that is usually a paid add-on.

How to Scan Multiple Pages into One PDF

If you need to scan a multi-page document into a single PDF file, the Windows Scan app makes this easy:

  1. In Windows Scan, select PDF as the file type.
  2. Click Scan for the first page.
  3. After it appears in the list, place the next page on the scanner and click Scan again.
  4. Repeat until all pages are scanned.
  5. Click Save — Windows combines all the pages into one PDF.

If you are using Windows Fax and Scan, you can scan multiple pages and then use File > Save As and choose PDF as the file type; it will merge them.

For a scanner with an automatic document feeder, you can load the whole stack and scan all pages at once. The software will create a single PDF if you select that option.

Common Scanning Problems and Fixes

Even with the right tools, scanning can fail. Here are the most frequent issues and how to solve them:

  • Scanner not detected: Try a different USB port, restart the printer, or reinstall the driver from the manufacturer’s site.
  • Scan is blank or black: The document may be placed face-down on the glass. Also check that the scanner lid is closed to block outside light.
  • Scan is blurry: Increase the DPI (300 or higher) and make sure the document lies flat on the glass.
  • Colors look wrong: Check the color format setting. Use “Color” for photos and “Grayscale” for text documents to avoid odd tints.
  • File too large: Lower the DPI or save as JPEG instead of PNG. For text, a 200-300 DPI grayscale JPEG is usually small and clear.
  • Windows Scan app missing: If you have an older Windows 10 version, update Windows or use Windows Fax and Scan instead.

If your scanner still doesn’t work, open Device Manager (right-click the Start button) and look under Imaging devices. If there is a yellow warning icon, the driver is not installed correctly — reinstall it.

What Resolution (DPI) Should You Use?

DPI stands for dots per inch — the higher the number, the more detail captured. But higher DPI also means larger files and slower scans. Here’s a practical guide:

  • 150 DPI: Good for quick previews or documents that will only be viewed on screen.
  • 300 DPI: Standard for text documents, forms, and anything you might print or run through OCR.
  • 600 DPI: Recommended for photos with fine detail or small text that needs to be enlarged.
  • 1200 DPI+: Only for film negatives or very small originals; produces huge files.

For most everyday documents, 300 DPI in grayscale or black-and-white is the best balance of quality and file size. If you are scanning a photo, use 300 DPI in color and save as JPEG.

Frequently Asked Questions

Why doesn’t my scanner show up in Windows 10?

Your scanner may not appear if the driver is missing, the cable is loose, or the device is turned off. Check the connection, restart the scanner, and try a different USB port. If it still doesn’t appear, go to the manufacturer’s website and download the latest driver for your model and Windows 10.

Can I scan to a PDF without extra software?

Yes. The Windows Scan app can save directly to PDF when you select PDF as the file type. Windows Fax and Scan also supports PDF output. Both are built into Windows 10, so no extra software is needed.

How do I scan a document from a printer that is not connected to my PC?

If your printer is on the same Wi-Fi network, Windows 10 can usually find it. Make sure the printer is connected to the same network as your PC. If it still doesn’t appear, use the printer’s own touchscreen (if it has one) to scan to a USB drive or email, then transfer the file to your computer.

What is the best file format for scanned documents?

For text documents, PDF is best because it preserves the layout and is easy to share. For photos, JPEG is smaller and works well for color images. PNG is lossless but creates larger files, so use it only when you need perfect quality, like for screenshots or line art.

Why is my scanned document so large?

Large file sizes usually come from high DPI or color mode. Reduce the DPI to 200-300 and use grayscale instead of color for text. Also, saving as JPEG instead of PNG will shrink the file significantly.

Can I scan a document using my phone instead of a scanner?

Yes, you can use the camera on your phone with a scanning app like Microsoft Lens (free) or Adobe Scan. These apps use the camera to capture the document, straighten it, and save it as a PDF. This is convenient for on-the-go scanning, but the quality may be lower than a dedicated scanner, especially in low light.
