Fax Software for Windows 10: Everything You Need to Know
There are three types of fax software for Windows 10: the built-in Windows Fax and Scan app, desktop programs that require a fax modem, and online fax services that work in any browser with no hardware. This guide covers every option, how they compare, and which one to use.
Frequently Asked Questions
What fax software comes built into Windows 10?
Windows 10 includes Windows Fax and Scan, a free app that has shipped with Windows since Vista. It can send and receive faxes, but only if you connect a USB fax modem and an active analog phone line. Without that hardware, it cannot transmit anything. You can find it by searching "Windows Fax and Scan" in the Start menu.
Can I use fax software on Windows 10 without a phone line?
Yes. Online fax services like mFax.to work entirely over the internet — no modem, no landline required. You open the service in any browser, upload your document, enter the fax number, and send. The service handles the conversion and delivery. This is the most practical option for the vast majority of Windows 10 users today.
Is there free fax software for Windows 10?
Windows Fax and Scan is free but requires a hardware fax modem (~$25–$50) and an analog phone line (~$15–$40/month). Several online services offer free tiers or trials — mFax.to has a free trial that lets you send faxes immediately. For occasional one-off faxes, services like GotFreeFax offer limited free pages with no signup.
What is the best fax software for Windows 10 in 2026?
For most users, the best choice is an online fax service. mFax.to is the top pick — no hardware, no installation, works in any browser, and delivers a confirmation receipt within minutes. If you already own a USB fax modem and an analog phone line, Windows Fax and Scan is a perfectly capable free option. Desktop programs like VentaFax suit users who want advanced scheduling or answering-machine features with local modem hardware.
Does Windows Fax and Scan work on Windows 10?
Yes, Windows Fax and Scan is available on Windows 10. On some installations it may need to be enabled via Settings → Apps → Optional Features → Add a feature. However, the app requires a USB fax modem and an analog (POTS) phone line to function — VoIP lines do not work reliably with it.
