Windows
Sending faxes from your Windows 10 computer doesn’t require a bulky fax machine—it’s built right into your system. ⚡ I’ve helped dozens of friends digitize their faxing process, and the Windows Fax and Scan app handles everything from scanning to sending without needing a printer.
The best part? It’s free, and you’ll be faxing documents in under 10 minutes once you get the hang of it.
You’ll need either a scanner or a modern smartphone to digitize your documents, plus a working internet connection if you’re using an online fax service.
Windows Fax and Scan works with most scanners, but if you’re scanning from your phone, apps like Microsoft Lens or Adobe Scan make the process even simpler.
For online faxing, services like eFax or MyFax integrate directly with your email, turning any PDF into a fax with just a few clicks.
Once set up, you’ll send faxes directly from your desktop, track delivery status, and even receive faxes as PDFs in your email inbox. No more waiting by the machine or dealing with paper jams—just clean, digital faxing that works like modern email.
I’ll walk you through both the built-in Windows tools and the easiest third-party alternatives, so you can pick what fits your workflow best.
The biggest stumbling block is usually driver issues or network setup for online faxing, but I’ve included troubleshooting steps for both. Whether you’re faxing medical forms, legal documents, or old-school business paperwork, this method keeps everything digital and hassle-free. Let’s get started—your first fax is just a few clicks away.

Step-by-step instructions for sending faxes digitally in Windows 10
Here's how to fax documents directly from your Windows 10 PC without needing a fax machine.
🖥️ Step 1: Set Up Windows Fax and Scan
Open the Start menu and search for "Windows Fax and Scan." This built-in tool lets you send faxes using your internet connection. If you don't see it, you may need to enable it through the Windows Features panel—search for "Turn Windows features on or off" and check the box for "Fax Services."
Once installed, launch the application. You'll need to configure your fax account first. Click "Fax" in the top menu, then "Fax Account Settings." Here, you can set up your outgoing fax number (this is what recipients will see as the sender ID). Use a number that matches your phone service or a virtual fax number if you're using an online service.
Click "Add" to create a new account. Enter your name, the fax number you want to appear on outgoing faxes, and any other details. Save the settings when done. This step ensures your faxes will be properly identified when received.
⌨️ Step 2: Prepare Your Document for Faxing
Open the document you want to fax in Microsoft Word, Adobe Acrobat, or any other application. Save it as a PDF or image file (JPEG, PNG, or TIFF) before proceeding. Faxes work best with black-and-white or grayscale documents—color faxes can sometimes appear faded or distorted when received.
In Windows Fax and Scan, click "New Fax" to begin. You'll be prompted to add a recipient. Enter the fax number you're sending to, along with any cover page details. The cover page is optional but recommended—it includes your contact information and a brief message about the document.
Click "Add" to attach your document. You can drag and drop files directly into the fax window or browse your files to select them. For multi-page documents, arrange the pages in the correct order before sending. This ensures the recipient gets the complete document in the right sequence.
💡 Step 3: Send the Fax and Verify Delivery
After attaching your document, click "Send" to begin the faxing process. Windows will convert your digital document into a fax format and send it through your internet connection. The process may take a few minutes, depending on the document size and your internet speed.
You'll receive a confirmation dialog when the fax is successfully sent. However, to ensure delivery, check your email for a notification from Windows Fax and Scan. Some internet fax services also provide a delivery report, which confirms whether the recipient's fax machine received the document.
If you don't receive a confirmation, wait 24 hours before resending. Some fax services may take time to process the transmission, especially if the recipient's fax line is busy or experiencing issues. Keep a record of sent faxes by saving the confirmation emails for your records.
💻 Step 4: Troubleshoot Common Issues
If your fax fails to send, first check your internet connection. A stable connection is critical for digital faxing. Restart your router if needed, or try switching to a wired connection for better reliability.
If the recipient's fax doesn't print, verify the fax number is correct. Some numbers may be formatted differently (e.g., with or without a country code). Also, ensure the recipient's fax machine is powered on and ready to receive faxes. Some businesses disable incoming faxes during off-hours.
For persistent issues, try sending a test fax to a known working number first. If that fails, consider using a third-party fax service like eFax or MyFax, which often provide better reliability and additional features like email-to-fax capabilities.
Tips & tricks for perfect digital faxing in Windows 10
Here's what I learned after helping dozens of people navigate Windows 10's built-in fax tool—these tricks save time and frustration.
The Setup Secret: If "Windows Fax and Scan" isn't showing up in your Start menu, you're not alone—this happens to most people. The fix is simple: search for "Turn Windows features on or off" and check the "Fax Services" box. This built-in tool works great once enabled, but many overlook this first step. I always double-check this before troubleshooting any other issues.
Document Prep Tip: For best results, save your document as a PDF or black-and-white image before attaching. Color documents often come out faded or distorted when faxed digitally. I've seen this happen with scanned receipts—always convert to grayscale first. Pro tip: Use the "Print to PDF" option in your document's print menu if you don't have Adobe Acrobat.
Delivery Confirmation Strategy: The 24-hour waiting period mentioned in Step 3 is crucial—don't skip this! Some fax services take time to process transmissions, especially if the recipient's line is busy. I recommend sending a test fax to your own number first to verify everything works. Save those confirmation emails—they're your receipt and proof of delivery.
Troubleshooting Shortcut: When your fax fails to send, my first move is always to check the internet connection. A stable connection is non-negotiable for digital faxing. As a last resort, try a wired connection instead of Wi-Fi—this has saved me countless times when wireless was acting up. Remember, faxing uses your internet connection just like any other data transfer.

Frequently asked questions
Got questions about faxing from your Windows 10 computer? You’re not alone! Here are some of the most common concerns—and their quick solutions—to help you fax like a pro without a printer.
Can I fax from Windows 10 for free?
Most free fax services online (like eFax or RingCentral) require an internet connection and may limit features. Windows 10 itself doesn’t have a built-in free fax tool, but you can use third-party apps like Microsoft Fax (if available) or online fax services with free trials. Always check for hidden costs or ads!
How long does it take to fax from a computer?
Faxing speed depends on your internet connection and the service you use. A standard fax (1-2 pages) usually takes 10-30 seconds to send. However, busy fax lines or slow networks can delay delivery. For urgent faxes, use a reliable paid service or check the recipient’s fax number for delays.
What file formats can I fax from Windows 10?
Most online fax services accept PDF, Word (DOC/DOCX), JPG, PNG, and TXT files. If your document isn’t in a supported format, convert it using free tools like Adobe Acrobat Reader or Microsoft Word. Always preview your fax before sending to avoid formatting issues!
What if my fax doesn’t send or gets rejected?
Troubleshooting steps:
- Check your internet connection—unplug and reconnect if needed.
- Verify the fax number is correct (no typos!).
- Ensure the file size isn’t too large (some services cap at 5MB).
- Try a different fax service if the issue persists.
Is faxing from a computer safer than using a fax machine?
Yes! Computer faxing reduces paper waste and eliminates the risk of jammed machines or ink shortages. However, always:
- Use secure fax services with encryption (look for HTTPS or VPN options).
- Avoid sending sensitive info via free public fax services.
- Double-check the recipient’s number to prevent misdelivery.
