Step-by-step guide
Open OneFaxNow in your browser
Open any browser — Chrome, Safari, Firefox, or Edge — and go to OneFaxNow.com. Click "Send a Fax" to open the fax form.
No account creation, no sign-up, no software to install. This works identically on macOS, Windows, ChromeOS, and Linux.
Upload your document
Click "Choose Files" or drag and drop from your desktop. You can select:
- PDF — from your desktop, Downloads folder, or cloud storage
- Photo — JPG or PNG scans and images
- DOCX / TXT — Word documents or plain text files
PDFs are automatically optimized for fax quality — converted to grayscale at 300 DPI for the sharpest output. Word files are converted on the server, so you do not need to export to PDF first.
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.
Optional: toggle "Add Cover Page" to include sender/recipient details and a message on the first page of your fax.
Pay and send
Review your fax details — number, email, page count, and price — then click "Pay & Send".
Pay with a credit or debit card, Apple Pay, or Google Pay. Your payment is authorized but not charged until the fax is delivered successfully.
Pay-on-success guarantee: If the fax fails after 3 automatic retries, the authorization is released and you're never charged.
Track your delivery
After payment, you'll see a live status page that updates in real time: Sending → Delivered.
- Watch transmission progress live in your browser
- Automatic retries if the line is busy (up to 3 attempts)
- Email confirmation when delivery is complete
Faxing from Mac vs. Windows vs. Chromebook
OneFaxNow works identically on every platform because it runs in your browser. But here is what you should know about each:
Mac (macOS)
Apple removed built-in fax modem support in macOS Sierra (2016). There is no native fax utility in any current macOS version. Browser-based faxing through OneFaxNow is the simplest method — no drivers, no hardware, no workarounds.
Windows PC
Windows 11 still includes "Fax and Scan" as an optional feature, but it requires a USB fax modem and a phone line — hardware most computers no longer have. OneFaxNow works in Chrome, Edge, or Firefox without any extra hardware.
Chromebook
ChromeOS has never had native fax support. OneFaxNow runs entirely in the Chrome browser — open the site, upload, and send. Nothing to install.
Computer faxing tips
Use PDF for best quality
PDF preserves formatting exactly. If your document is a Word file, OneFaxNow converts it automatically — but starting with PDF gives you the most control over how the fax looks.
Drag and drop from your desktop
On any computer, you can drag files directly from your desktop or file manager into the upload area. Faster than clicking "Choose Files" when you have multiple documents.
Multi-page documents
Upload up to 15 files per fax (50 pages total). OneFaxNow automatically merges them into one transmission in the order you add them.
Medical or sensitive docs?
Toggle HIPAA mode before sending. You get encrypted transmission, auto-deletion of files, full audit trail, and an instant BAA.

How do I fax from a Mac?
Open Safari or Chrome on your Mac, go to OneFaxNow.com, upload your document, enter the fax number, and pay. Apple removed native fax support in macOS Sierra (2016), so browser-based faxing is now the standard method for Mac users.
Does Windows Fax and Scan still work?
Windows Fax and Scan is still available in Windows 11 as an optional feature, but it requires a USB fax modem and a phone line — hardware most modern PCs do not have. Using an online fax service like OneFaxNow is simpler and requires no additional hardware.
