Send fax online without a fax machine

The simplified fax service for your modern business.

These days, it’s possible to send and receive faxes without having to touch an actual fax machine. Thanks to internet faxing or online fax technology, it’s now possible to fax over the world wide web by means of sending any document you create through email or with the use of dedicated software on your computer or devices.

Email to fax is actually one of the more common ways to send a fax from a computer. With this technology, you can attach documents such as Microsoft® Word documents or PDF files to a regular email and then send them to a specific fax number so that the other party can receive them via their fax machine or email inbox. To do this, you need to subscribe to one of the third-party online fax services available in the market and get assigned a fax number.
