Think back to the last time you sat around on one of those huge, clunky fax machines.

It's probably been a while, right? While this old school hardware is undoubtedly out of date, faxing is by no means dead.

It is actually very much alive. Fortunately, we have better technology.

The best online fax services make sending secure faxes a breeze for individuals and businesses of all sizes, without the need for ugly, expensive, or tricky hardware.

However, there are dozens of providers to choose from, so making the right choice is often more difficult than actually using the service. To make your decision easier, I've narrowed it down to my six top recommendations and reviewed them.

The top 6 options for online fax services

  1. mFax – best online fax services for multiple users
  2. RingCentral Fax – premier all-in-one online fax service
  3. HelloFax – best for cloud storage integrations
  4. SRFax – the most secure online fax service
  5. FaxBurner – the best online mobile fax service
  6. Biscom 123 – the cheapest online fax service

How to choose the best online fax service for you

There are dozens of online fax service providers to choose from. Hence, it is difficult to know which one is perfect for your business, especially if you are not entirely sure what to look for.

All of the options on this list are excellent. However, they may not work for everyone.

So don't forget to consider the following factors as you go through the decision-making process to narrow things down and find the perfect fit.

Number of users

As a business, you likely need multiple user accounts. Different services have different pricing plans. Hence, it is important to consider the number of accounts you will need.

Some options can limit the number of users without getting past it. Others may offer additional user accounts with an additional monthly fee. So this plays a huge role in how much you can pay each month.

Even so, most of the smaller businesses don't have any issues with account restrictions.

However, large companies with multiple departments that require fax capabilities can run into problems with low-limit plans.

Cloud storage integrations

Most businesses rely on cloud storage tools. Whether you depend on Microsoft 365 or Google's G Suite, your employees likely use these tools on a daily basis to create and archive documents.

Therefore, it is important to consider these integrations if you and your team need to store documents that you send or receive via online fax.

This can help streamline your document management processes.

Page restrictions

Most providers charge an additional fee if you exceed the number of pages in your plan. So you need to consider your company's needs when it comes to monthly fax volume.

Many vendors set low thresholds for this to encourage you to upgrade to a better plan.

So, it's important to choose a plan that has enough pages per month, plus a reasonable fee for page overruns (just in case). However, online unlimited-plan fax services are a better option for businesses that want to send and receive high volumes every month.

Document archiving

If you are using an online fax service to send and automatically digitize documents, it should also come with the document filing system. This can significantly streamline and automate your document management processes.

Some online fax services offer online databases so that users can easily save faxes. However, some offer no archiving functionality and some do not offer any archiving functionality. Without this, you'll have to print, scan, and save everything by hand.

Which … can be an incredibly time consuming process.

So, pay close attention to this in your decision, especially if you need it now or in the future.

Industry-specific use

There are many different general purpose online fax services available. However, sometimes certain providers are more suitable for certain industries.

Healthcare is a great example of this as you deal with sensitive information and legal requirements in dealing with it. So you need a service that is secure and meets these requirements.

Healthcare isn't the only industry of its kind, however, so it's important to consider your industry's requirements and regulations before making your final decision.

The different types of online fax services

Not all online fax services are created equal.

Before we get into the reviews, let's dig into the different types of online fax services so that you know exactly what to look for as you go through the process.

Web or cloud based services

The most common online fax services are cloud or browser-based. All you have to do is create an account and you're good to go.

Web-based fax services are known for high quality faxes and ease of use.

And they often offer a wide range of cloud-based integrations with platforms like G Suite and Dropbox that make life easier when you want to archive your communications in the cloud.

Mobile fax services

With mobile fax services, users can fax directly from their smartphone. Mobile faxing is essentially as convenient and easy as taking a photo.

Plus, you don't have to wait to be at your computer or rely on team members to sit in front of a desktop to send and receive messages.

Some providers may also support desktop or web-based use, while others are mobile-only.

So keep that in mind when deciding which provider is best for you and your team.

RingCentral Fax is another popular online fax service. With a solid feature list, flexible user numbers, and a robust security suite, this is my first recommendation for an online fax service.

But their paid plans are affordable, starting at $ 9.99 per month.

# 4 – SRFax Review – The Most Secure Online Fax Services

SRFax is a great option for companies with high security concerns. The transmission of information over the Internet always carries the risk of eavesdropping.

And for certain industries like healthcare, safety is even more important.

Healthcare providers rely on faxing to transfer sensitive patient information. Therefore, the fax services they use must comply with the Health Insurance Portability and Accountability Act (HIPAA).

SRFax offers multiple levels of data encryption while maintaining a user-friendly interface, making it an excellent choice for high security industries.

In addition to HIPAA compliant fax services, SRFax has multiple tiers and plans to suit all security levels and business sizes.

The prices are affordable. Monthly plans start at $ 3.29 per month. Or, you can sign up for a 60-day non-health trial to try it out before you commit.

# 5 – FaxBurner Review – Best Online Mobile Fax Service

FaxBurner differs from other online fax services because of its well-designed, easy-to-use IOS and Android apps. FaxBurner makes sending faxes as easy as taking a photo and receiving them straight to your inbox.

Setup is quick and easy. In addition, the platform offers users a temporary fax number that expires after 24 hours without upgrading to a paid plan.

# 6 – Biscom 123 Review – Cheapest Online Fax Services

If your business only needs to send faxes occasionally, Biscom 123 is an incredibly affordable option. As a leading telecommunications company, Biscom simplifies online faxing for both companies and private individuals with a clear interface.

You can also try it for free for 30 days to see if it's right for your business without the need for a credit card. However, no archive records of your communications are kept. So keep that in mind.

Depending on your faxing needs, Biscom 123 offers different plans that allow you to send up to 300 pages with support for multiple team members.

However, this does not mean that they are suitable for everyone in every situation.

So don't forget to consider the factors we talked about and get free trials as you go through the process of choosing the best online fax services for you and your team.
