Internet fax (also known as online fax or cloud-based fax) is a technology that uses Internet Protocol (IP) to send and receive faxes online. Instead of using fax machines or fax servers, which require telephone networks and landline phones, online fax uses IP for transmission and users get access to their faxes from almost any internet-enabled device.

Web fax, mobile fax, email fax, and fax API are some of the different ways to use internet fax for sending and receiving documents online. Depending on the online fax provider you choose, you may be offered some or all of these tools and services.

Say Goodbye to Your Traditional Fax Machine

As mentioned earlier, traditional fax machines use telephone networks to establish the connection between two fax devices in order to transmit documents and copies in the form of pulses (Wikipedia). To send and receive faxes using this old-school method, you are going to need a working fax machine (with papers, toner, and ink),  a landline phone, some extra space to place your machine, and some extra time and energy to set up the device. When it comes to receiving, you must be beside the fax machine to receive them, and most importantly, you don't get to choose which document to print and which not.

Disadvantages of using traditional fax machines:

  1. They need a landline phone number
  2. They don’t support multitasking
  3. They cannot be reached easily
  4. They cannot be moved easily
  5. They are not as secure
  6. They may charge you for international calling
  7. They are not environmentally-friendly

Different Ways to Send and Receive Faxes with Internet Fax

Note that, for sending and receiving faxes through a cloud-based faxing solution, either the sender, the receiver or both should have a valid internet fax subscription, and you can easily send faxes to any fax machine or fax server with your online faxing account.

Web Faxing: For this method, you get to use a desktop or web-based application to do all your faxing. All your documents will be stored in the cloud and you just need to have a PC or laptop with an internet connection to have access to your faxes. Usually, you'll be informed with a notification via Email or Push when there is a new fax message in your inbox.

Mobile Faxing: For this method, your Android or iOS phone/tablet turns into a fully functional fax machine, and you even get to use your device's camera to scan physical documents and turn them into ready-to-send documents via fax.

Email Faxing: For this method, sending a fax is as easy as sending an email. You get to send faxes from any mail server including Gmail, Yahoo, and Outlook, to any fax machine or internet fax. On the other side, your received faxes can be found in your emails.

Fax API: The programmable fax web service enables you to do all your faxing activities from virtually any application, software, or system.


While sending a fax seems to be outdated and odd, most lawyers, insurance companies, healthcare organizations, regulated industries, and government agencies still send and receive documents over fax.

While fax machines are so inconvenient, people still need faxing. That's where the Internet faxing solutions emerge and make faxing a more pleasant and productive experience. Online faxing offers a secure and reliable solution to transmit documents digitally and enables its users to store their documents in a safe cloud storage and access them from anywhere anytime.
