Best Online Fax Services

5 Best Online Fax Services of 2023

Faxes? One question comes to mind when you hear this. “Who uses fax machines anymore?” Well, truth be told, there are still thousands of businesses that use faxes as a way to communicate. However, there is no physical fax machine involved. Instead, companies are using online fax services to send and receive faxes.

Chances are, you could still pay to use a physical fax machine at your local office supply store, but there is no need to do this if you start using electronic fax. There is a lot to consider when you are trying to narrow down the best online fax services available.

Below, we are going to go over what I think are the best ones out there. This way you have a place to start and have some to compare side-by-side. Before we do that, let’s talk about online fax services and some of the other things you need to know.

How Does Faxing Online Work?

Faxing online and traditional faxing are two very similar office functions that work in two very different ways. For decades, individuals and businesses used dedicated fax machines. These machines converted scanned documents into a digital audio tone. This conversion was then sent out over a dedicated telephone line.

When that data reached another traditional fax machine, the data received would be turned into a facsimile of the original document. The concept was a brilliant one.

However, the additional needs for things like extra machinery, a separate telephone line, ink, and paper, slowly drove up the cost of traditional faxing.

Since cost continued to go up, other ways of communication were put into place. Through all of this, internet fax services started to become more and more popular. In comparison, faxing online works one of two ways.

Most electronic fax service providers allow you to send digital attachments through your email client. This happens when you type the recipient’s fax number as part of a “special” email address. Email-based faxing can also be done through third-party integrations like Microsoft Outlook.

The second option you have is web-based clients. These use forms and upload prompts that happen on a proprietary website that handles all the incoming and outgoing messages.

There are even some online fax services that still integrate with the old-school physical fax machines. This is a way to bridge the gap between traditional and online faxing.

Benefits of Online Fax Services

There are several good benefits that present themselves when you choose to adopt an internet fax service. At the forefront of these benefits is the overall cost. Going this route will reduce costs significantly.

Think about it. A physical fax machine in an office can require constant attention, supplies, and care. Keeping up with regular maintenance, ink and toner, and dips in productivity while your employees stand around waiting to use the fax machine can really start to add up.

This entire cost and process can be eliminated by choosing one of the many excellent online fax services.

There is also a huge reduction in paper waste. You see, online fax services provide a way to store all your faxes in the cloud. This means no stuffing paper into file cabinets or anywhere else. This is also a great way to say your company in “going green.”

What to Look for in an Online Fax Service

Before we dig into the best online fax services out there today, let’s take a look at the things you should be looking for when choosing which electronic fax service to go with.

Remember, whether or not you need a HIPAA-compliant provider or only send faxes every now and then, the way messages are transmitted remains virtually the same. When researching online fax services, it is a good idea to take a closer look at what all is offered.

Some of the main things to look into and consider include:

Proprietary App Support: Since just about everyone has a smartphone these days, it is important to know whether or not the electronic fax service you choose has app support for your Apple or Android phone. This makes accessing all tools and sending faxes online much easier.

Encryption: Online security is as important as ever. Faxes oftentimes contain sensitive data and information. This information needs to be protected. The best online fax services will provide high-end encryption like SSL and PGP to protect your data.

Dedicated Fax Number: Most online fax vendors will provide you with a toll-free or local fax number that can be used. In addition, long-distance or international numbers can be added for a fee. That being said, if you already have a dedicated fax number, then most of the best online fax services will allow you to port that number over to your new service.

Cloud Storage: The amount of cloud storage you need to store all the faxes you will have coming in and going out depends on the size of your company and how often the system is being used. Always make sure that you have enough storage to save all your documents. You will also want to look at options regarding recovery, keyword search, and server uptime.

And last, look into email-to-fax-support and International faxing options.

They specialize in HIPPA-compliant faxing as well as a number of other features geared toward the health care industry.

As stated above, Sfax is on the more expensive side. You can lower the cost by paying for a year up-front.
