How to Fax over WiFi — No Phone Line Required
Your WiFi connection is all you need. Open OneFaxNow on any device, upload a document, enter the fax number, and pay. No fax machine, no landline, no account. Your fax is delivered in minutes from any WiFi network — home, office, hotel, or coffee shop.
How WiFi faxing works
Traditional fax machines send documents over a phone line. WiFi faxing skips the phone line entirely. Instead, an online fax service converts your document into a fax-compatible signal and transmits it over the internet to the recipient's fax machine.
All you need is a device with a web browser (phone, laptop, tablet) and a WiFi connection. OneFaxNow handles the rest — upload your file, enter the destination fax number, and the service delivers it directly to the recipient's fax machine.
WiFi printer does not mean WiFi fax
A common misconception: many people assume their WiFi-enabled "all-in-one" printer can fax over WiFi. It cannot. The WiFi on your printer connects it to your computer for printing and scanning. The fax function still requires a phone line plugged into the wall. To fax without a phone line, you need an internet-based fax service like OneFaxNow.

Step-by-step: Fax over WiFi
Connect to WiFi and open OneFaxNow

Upload your document
Tap or click "Choose Files" to upload your document. OneFaxNow accepts PDF, DOCX, JPG, PNG, TIFF, and TXT files. You can upload up to 15 files (50 pages total) in one fax.
Tip: On your phone? Use the OneFaxNow app to scan a paper document with your camera. It auto-straightens and enhances for fax quality.
Enter the fax number and your email
Type the recipient's U.S. or Canada fax number. The form auto-formats as you type — just enter the digits.
Enter your email address to receive a delivery confirmation when the fax goes through.

Is faxing over WiFi secure?
Yes — and it is actually more secure than traditional phone-line faxing. Traditional faxes travel as unencrypted analog signals over phone lines. Anyone with access to the line can intercept them.
When you fax over WiFi with OneFaxNow, your document is encrypted with TLS during upload and transmission. Even on a public WiFi network (hotel, coffee shop), the connection between your browser and OneFaxNow is encrypted end-to-end via HTTPS.
Sending medical or sensitive documents?
Toggle HIPAA mode before sending. You get encrypted transmission, automatic file deletion after delivery, a full audit trail, and an instant Business Associate Agreement (BAA). HIPAA fax starts at $6.50 for 1-10 pages.

Frequently asked questions
Can I fax over WiFi without a phone line?
Yes. OneFaxNow sends your fax over the internet, not a phone line. Connect to any WiFi network, open OneFaxNow.com, upload your document, enter the fax number, and send. No phone line, no fax machine, no special hardware.
Can my WiFi printer fax without a phone line?
No. A WiFi printer uses WiFi to communicate with your computer for printing and scanning, but the fax function still requires a phone line. To fax without a phone line, use an online fax service like OneFaxNow instead of your printer's built-in fax.
Is faxing over WiFi secure?
Yes. OneFaxNow uses HTTPS/TLS encryption for all data transmission. This is actually more secure than traditional phone-line faxes, which transmit unencrypted analog signals. For medical documents, enable HIPAA mode for encrypted transmission, automatic file deletion, and an instant BAA.
Can I fax from public WiFi at a hotel or coffee shop?
Yes. OneFaxNow works on any WiFi network, including public networks at hotels, coffee shops, airports, and libraries. Your connection to OneFaxNow is encrypted via HTTPS, so your document is protected even on shared networks.
How much data does faxing over WiFi use?
Very little. A typical fax uses less than 5 MB of data — comparable to sending a few photos. Even a slow WiFi connection is more than fast enough to fax.

No. You do not need a fax machine, a phone line, a printer, or any hardware. Just a device with a web browser (phone, laptop, tablet) and a WiFi connection. Go to OneFaxNow.com and send.
