Quick Summary: In 2026, you don't need a phone line to fax. The most efficient method is using a web-based service like mFax.to. It works on any OS, handles PDF/Word files, and ensures your documents are encrypted during transit.
In 2026, the "paperless office" is finally a reality for most, yet the fax remains a staple in legal, healthcare, and government sectors due to its status as a legally binding form of communication.
If you're sitting at your desk wondering how to send a document to a 10-digit fax number without a physical machine, you’re in the right place. This guide covers the three primary ways to fax from your computer today.
Why Do We Still Fax in 2026?
Despite the rise of secure client portals, faxing remains relevant for three reasons:
- Legal Admissibility: Many jurisdictions still prioritize faxed signatures over unencrypted email attachments.
- Security: Unlike email, which can sit on multiple servers, a secure fax (especially via mFax.to) provides an end-to-end audit trail.
- Legacy Interoperability: Thousands of institutions still rely on fax infrastructure.
Method 1: The Modern Way (Web Browser) — Recommended
This is the universal solution. Whether you are on a Windows PC, MacBook, Linux machine, or even a Chromebook, the web version of mFax.to allows you to send faxes as easily as sending an email.
How to Send a Fax Online in 60 Seconds:
- Access the Dashboard: Navigate to mFax.to.
- Upload Document: Drag and drop your PDF, DOCX, or JPG.
- Input Recipient: Enter the fax number (include the country code for international faxes).
- Add a Cover Page (Optional): Type a brief note for the recipient.
- Click Send: The system converts your digital file into a fax signal.
- Get Confirmation: You will receive a digital receipt once the recipient's machine confirms delivery.
Try it now: Drag your PDF to mFax.to to see how easy it is to prepare a fax.
Method 2: Windows 10 & 11 (Windows Fax and Scan)
Windows still includes the "Windows Fax and Scan" app, but there is a significant hurdle for modern users.
The Requirement: To use this, your computer must have a physical fax modem and be connected to a physical analog phone line.
- The Reality: Most modern laptops haven't had internal modems for over a decade.
- The Cost: By the time you buy a USB fax modem and pay for a monthly landline, you could have sent thousands of faxes via mFax.to.
Steps if you have the hardware:
- Open the Start Menu and type "Windows Fax and Scan."
- Click New Fax in the toolbar.
- Follow the modem setup wizard.
- Compose your fax and click Send.
Method 3: Faxing From a Mac (macOS)
Apple removed fax support from its "Printers & Scanners" settings in recent macOS updates as they moved toward a fully wireless ecosystem.
The Solution: Mac users are the primary demographic for web-based faxing. Because macOS handles PDFs natively (via Preview), using mFax.to is seamless.
- Save your document as a PDF.
- Open Safari/Chrome and go to mFax.to.
- Upload and send.

| Feature | mFax.to (Online) | Windows Fax & Scan | USB Modem (Mac) |
|---|---|---|---|
| Phone Line Required | No (Internet Only) | Yes (Analog) | Yes (Analog) |
| Hardware Needed | None | Fax Modem | USB Modem |
| Setup Time | 30 Seconds | 30 Minutes | 20 Minutes |

Advanced Security: Is Your Fax Protected?
When sending documents like medical records or legal contracts from a computer, security is non-negotiable.
Traditional fax machines are often located in communal office spaces where anyone can pick up a printed page. By using the mFax.to web version, you ensure:
- Data at Rest Encryption: Your documents are stored securely.
- Data in Transit Encryption: Faxes are sent via encrypted protocols.
- Audit Trails: Know exactly when a document was sent, received, and by whom.
