Windows Fax and Scan is a free built-in tool for sending faxes and scanning documents on Windows 10 and 11. This guide covers setup, how to send and receive faxes, scanning tips, troubleshooting, and modern alternatives.
Frequently Asked Questions
Does Windows Fax and Scan require a phone line?
Yes. Windows Fax and Scan requires a traditional analog landline (POTS) and a hardware fax modem. It cannot send faxes over WiFi, VoIP, or the internet. If you don't have a landline, use an online fax service like [mFax.to](https://mfax.to) instead.
Is Windows Fax and Scan available on Windows 11?
It was available as an optional feature in early Windows 11 builds, but Microsoft has progressively removed it — particularly in Windows 11 Enterprise 24H2 and all ARM64 devices. Use Settings > System > Optional Features to check if it's available on your build.
How do I install Windows Fax and Scan on Windows 10?
Go to Settings > Apps > Optional Features > Add a feature, search for "Windows Fax and Scan," and click Install. On Windows 11, go to Settings > System > Optional Features > View features and search for it there.
Can Windows Fax and Scan scan to PDF?
Not natively. Windows Fax and Scan saves scans as TIFF, JPEG, PNG, or BMP. To get a PDF, use your printer's software, Microsoft Print to PDF, or a free tool like [mFax's document converter](https://mfax.to/document-converter/).
How do I fax from Windows without a modem or phone line?
Use an online fax service. [mFax.to](https://mfax.to) works in any web browser on Windows 10 or 11 — upload a document, enter the recipient's fax number, and send. No modem, no phone line, no hardware required.
