Do I need a fax machine to send a fax online?

No. Online faxing sends your document over the internet to the recipient's fax machine or fax line, so you never touch a physical machine.

Is sending a fax online free?

Yes. OnlyFaxes lets you send faxes for free with no signup. A dedicated number is available if you need your own line or higher page limits.

Sending a fax online replaces the machine, the phone line, and the busy signal with a web page. Here's how to send one for free with OnlyFaxes.

Open the fax tool: Go to the OnlyFaxes home page. The free fax tool loads right away - there's nothing to install and no account to create.
Upload your document: Drag in a PDF or image, or pick a file from your device. We convert it into a clean, fax-ready page automatically.
Enter the fax number: Type the recipient's fax number for the US, Canada, UK, or Mexico. You can add a cover sheet if you'd like one.
Send and confirm: Add your email so we can send a delivery receipt, then hit Send Fax. You'll know within minutes when it arrives.
