The simplest way to scan a document
The fastest route is to use your scanner's software, which came with the device or is available free from the manufacturer's website. Place your document face-down on the glass, open the software on your computer, and click the scan button. The document appears as an image file on your computer within seconds.
If your scanner did not come with software, or you cannot find it, most computers have a built-in scanning tool. On Windows, search for "Windows Scan" in the Start menu. On Mac, open the "Image Capture" process in your Applications folder. Both work with any scanner connected by USB cable or network.
The document will save as a PDF or image file (usually JPG or PNG) in a folder you choose. You can then move it, email it, print it again, or store it in a cloud service like Google Drive or OneDrive.
Key Takeaways
- Most scanners come with their own software, which is the easiest method — place the document and click scan in the program.
- Windows has a free "Windows Scan" tool and Mac has "Image Capture" built in, so you do not need to install anything if your scanner software is missing.
- Your document saves as a file (usually PDF or JPG) in a folder you pick, and you can move or email it afterward.
- A USB cable connects most home scanners; network scanners connect through your WiFi and may require setup the first time.
- Flatbed scanners work best for single pages and documents; automatic feeders are faster if you have many pages to scan at once.
Using your scanner's own software
Open the software that came with your scanner. The name varies by brand — it might be called "Canon IJ Scan Utility", "Epson Scan", "HP Scan", or something similar. If you do not see it on your computer, check the manufacturer's website and read it for free using your scanner's model number.
Place your document face-down on the glass surface of the scanner. Close the lid gently. In the software window on your computer, you will see a preview of what the scanner sees. Check that the document is straight and fully visible in the preview.
Click the button labeled "Scan", "Start", or a similar word. The scanner will make noise and light up as it reads the document. When it finishes, the scanned image appears in the software window. Choose where to save the file — the software will ask you to pick a folder and give the file a name. Click "Save" and the file is now on your computer.
Using Windows Scan or Mac Image Capture
If you cannot find your scanner's software, Windows and Mac both have free tools built in. On Windows 10 or 11, click the Start button, type "Windows Scan", and open the app that appears. On Mac, open Finder, go to Applications, then Utilities, and double-click "Image Capture".
In Windows Scan, you will see a dropdown menu at the top that says "Scanner". Click it and select your scanner from the list. Place your document on the scanner glass and click the blue "Scan" button. The scanned image appears in the window. Click "Save" at the bottom, choose a folder, and the file is saved.
In Image Capture on Mac, your scanner appears in the left sidebar under "Devices". Click it to select it. Place your document on the scanner and click the "Scan" button. Choose where to save the file in the dialog that appears, then click "Save". The file is now on your computer.
Understanding file types and where files save
Your scanned document will save as one of three types. A PDF is best for documents you want to keep looking exactly the same — text, forms, and contracts all stay formatted. A JPG is a photo-like file that works everywhere but takes up more space. A PNG is similar to JPG but slightly better quality; it is less common for scanning but some software offers it.
When you scan, the software asks you to choose a folder where the file will live. Most people save to "Documents" or "Desktop" so they can find it easily. You can move the file later by dragging it to a different folder, or by right-clicking it and choosing "Move".
If you scan the same document many times, give each file a clear name so you can tell them apart. Instead of "Scan001", try "Lease_2024" or "Tax_Return_2023". The software usually lets you type a name before you save.
Scanning multiple pages into one file
If your scanner has an automatic feeder — a tray that holds a stack of pages — you can scan many pages at once. Load all pages into the feeder face-up, with the first page on top. In your scanner software, look for an option that says "Continuous Scan", "Batch Scan", or "Multiple Pages". Select it, then click Scan. The scanner will pull pages through one at a time and combine them into a single PDF file.
If your scanner only has a flatbed (the glass surface), you must scan one page at a time. Scan the first page, then place the second page on the glass and scan again. Most software will ask if you want to add another page to the same file. Click "Yes" or "Add Page", and the pages combine into one document.
When all pages are scanned, click "Save" and choose your folder. The entire document — all pages together — saves as a single file. This is much easier than having separate files for each page.
Connecting your scanner to your computer
Most home scanners connect by USB cable. Plug one end into the back of the scanner and the other into an open USB port on your computer. Windows and Mac will recognize the scanner automatically. If the software does not open on its own, search for it by name and open it manually.
Some newer scanners connect through WiFi instead of a cable. Turn on the scanner and look for a WiFi setup button or menu on the scanner's screen. Follow the on-screen steps to connect to your home network. On your computer, open the scanner software and it should find the scanner on the network. This takes a few extra minutes the first time but means you do not need a cable.
If your computer does not recognize the scanner after plugging it in, restart both the scanner and the computer. If it still does not appear, visit the manufacturer's website, read the latest driver software for your scanner model, and install it. A driver is a small program that teaches your computer how to talk to the scanner.
Fixing common scanning problems
If the scanned image is too dark or too light, look for a brightness or contrast setting in your scanner software before you scan. Most software has a preview window where you can adjust these settings and see the result before you commit. Scan again with the new settings.
If the image is blurry, make sure the document is lying flat on the glass and the lid is closed. Dust or fingerprints on the glass can also blur the image — wipe the glass gently with a soft, dry cloth before scanning. If the document itself is wrinkled or damaged, the scan will show those flaws too.
If the scanner is not appearing in your software, unplug the USB cable, wait ten seconds, and plug it back in. If it still does not appear, restart your computer. If you are using a network scanner, make sure your computer and scanner are on the same WiFi network.
Frequently Asked Questions
Can I scan directly to email or cloud storage like Google Drive?
Some scanner software has a button to send scans directly to email or cloud services, but not all do. Check your software's menu for options like "Send to Email" or "Save to Cloud". If your software does not have this, scan to your computer first, then open the file and email it or upload it to Google Drive manually — this takes only a few extra seconds.
What is the difference between scanning at 300 DPI and 600 DPI?
DPI (dots per inch) controls how detailed the scan is. 300 DPI is fine for most documents, forms, and contracts — the text is clear and readable. 600 DPI or higher is better if you are scanning old or faded documents, or if you plan to print the scan later. Higher DPI makes the file larger, so it takes longer to scan and uses more storage space.
Do I need special software to scan, or can I use what came with my scanner?
The software that came with your scanner is usually the best choice because it is made for that specific model. If you do not have it, Windows Scan and Mac Image Capture work with almost any scanner and are free. You do not need to buy anything.
Can I scan a document that is larger than the scanner glass?
No, the scanner can only see what fits on the glass at once. For large documents, scan the parts that fit, then move the document and scan the next section. You will have multiple image files that you can arrange or combine later using a PDF editor or image software.
How do I organize scanned documents so I can find them later?
Create folders on your computer for different types of documents — one for taxes, one for medical records, one for contracts, and so on. Save each scan with a clear name that includes the date or document type, like "Tax_Return_2024" or "Lease_Signed_Jan2024". This makes searching much faster than looking through files named "Scan001".
