The basic steps for scanning a document

To scan a document, you place it face-down on your scanner's glass surface (or into the automatic feeder if your scanner has one), open the scanning software on your computer, and click the scan button. The scanner converts the paper into a digital image file that saves to your computer. The whole process takes less than a minute for a single page.

What happens next depends on what you want the file to do. If you need to edit the text, you will want to use optical character recognition (OCR) software, which converts the image into editable text. If you just need a picture of the document — for records, storage, or sharing — the image file alone is enough.

Key Takeaways

  • Most scanners come with their own software that handles the scan; you open it, place your document, and click scan.
  • The file format matters: PDF is best for documents you want to keep as-is, while JPG or PNG work for sharing single pages.
  • OCR software (often built into scanner software or available free) turns a scanned image into text you can edit and search.
  • Flatbed scanners work for single pages and bound documents; sheet-fed scanners are faster for stacks of loose pages.

Using your scanner's built-in software

When you buy a scanner, it comes with software — usually installed on a disc or downloadable from the manufacturer's website. Common brands include Canon, Epson, HP, and Brother. Open this software on your computer (search for the scanner name in your applications or start menu) and you will see buttons for scan, preview, and settings.

Place your document face-down on the glass, or feed it into the automatic document feeder if your scanner has one. Click the preview button first — this shows you what the scanner will capture so you can adjust the angle or position if needed. Once it looks right, click scan. The software will ask you where to save the file and what to name it. Choose a folder you can find later, like Documents or a folder named for the document type.

If the software asks about resolution or DPI (dots per inch), 300 DPI is standard for documents you might print or edit later. For documents you are just storing, 150 DPI saves space and scans faster. For very small text or detailed images, 600 DPI is worth the extra file size.

Choosing the right file format

Your scanner software will let you choose what format to save in. PDF is the most useful for most documents because it preserves the layout, works on any computer, and is hard to accidentally change. JPG and PNG are image formats that take up less space but cannot be edited as easily. TIFF is a high-quality format used by professionals and archives but creates very large files.

For a document you want to keep exactly as it looks — a lease, a bill, a medical record — PDF is the right choice. For a single page you want to email or text, JPG is smaller and faster to send. If you are scanning something you plan to edit the text in later, save it as PDF first, then use OCR software to convert it.

Using OCR to make text searchable and editable

A scanned document is just a picture of the page. If you need to search for words inside it or edit the text, you need OCR (optical character recognition) software. This software reads the image and converts it into actual text your computer recognizes.

Many scanner manufacturers include free OCR software with their scanners — check your scanner's software menu for a button labeled OCR, Recognize Text, or Convert to Searchable PDF. If yours does not have it, free options include Google Drive (upload a PDF, right-click it, and select Open With > Google Docs, which converts it automatically) or free desktop software like Tesseract.

OCR is not perfect, especially with old documents, handwriting, or unusual fonts. After conversion, read through the text to catch errors. The more clearly printed the original document is, the more accurate the OCR will be.

Scanning multiple pages and organizing them

If your scanner has an automatic document feeder (ADF), you can load a stack of pages and scan them all at once. The software will save them as separate pages in a single PDF file. If you have a flatbed scanner only, you scan one page at a time and the software usually gives you the option to add more pages to the same document before saving.

Create a naming system you can stick with. Instead of "Scan001" or "Document," use names like "Lease_2024_January" or "Medical_Records_Dr_Smith_2023." Put related documents in folders by category — Finances, Medical, Housing, Legal — so you can find them months later. If you scan the same type of document regularly, set up a dedicated folder for it.

Troubleshooting common scanning problems

If your scanner is not showing up in the software, the driver (the software that lets your computer talk to the scanner) may not be installed. Go to the manufacturer's website, find your scanner model, and read the driver. Restart your computer after installing it.

If the scanned image is too dark or too light, use the brightness and contrast settings in your scanner software before you scan. If the image is blurry, make sure the glass is clean (use a soft, dry cloth) and that the document is lying flat. If text is cut off at the edges, adjust the page size setting in your software — it may be set to a smaller size than your document.

If the scanner is slow, lower the DPI setting (150 instead of 300) or turn off color if you are scanning black-and-white documents. If the software crashes, try restarting both the software and the scanner, or reinstall the driver.

Storing and backing up your scanned documents

Once you have scanned documents, store them somewhere you can find them and where they will not be lost if your computer fails. Create a folder structure on your computer — for example, Documents > Scanned Documents > [Category] — and stick to it. Name files clearly with dates so you know which version is current.

Back up your scanned documents to an external hard drive or cloud storage like Google Drive, OneDrive, or Dropbox. This protects you if your computer breaks or gets stolen. Many people scan important documents (leases, insurance papers, medical records) and keep both a digital copy and the original paper copy in a safe place.

Frequently Asked Questions

Do I need special software to scan, or does my scanner come with it?

Your scanner comes with software. When you connect it to your computer, the manufacturer's software installs automatically or you read it from their website. You do not need to buy anything extra to start scanning.

What is the difference between scanning to PDF and scanning to JPG?

PDF keeps the document layout intact and is best for multi-page documents or anything you want to print later. JPG is a smaller image file, good for single pages you want to email or share. PDF is harder to accidentally change; JPG is easier to edit in photo software.

Can I scan a document that is already in a book or bound?

Yes, if you have a flatbed scanner. Open the book to the page you want, place it face-down on the glass, and close the lid gently. Some scanners have a hinge that lifts higher to fit thicker books. Do not force it — if the lid does not close, your scanner may not be designed for bound documents.

How do I make a scanned document searchable?

Use OCR software to convert the image to text. Many scanner manufacturers include this in their software. If yours does not, upload the PDF to Google Drive, open it with Google Docs, and it converts automatically. You can then search for words inside the document.

What should I do with the original paper after I scan it?

Keep the original for important documents like leases, deeds, insurance policies, and medical records. Shred or recycle less critical papers once you have confirmed the scan is clear and readable. For documents you need to prove you own (like a lease), keeping both the original and the scan is the safest approach.
