The Best Online Fax Services of 2021

When choosing an online fax service for your small business, you should consider which features matter the most to you. If your company only needs to receive faxes from time to time, you don't need a service with a high monthly page allotment for sending faxes. If you run a medical practice, it would behoove you to seek out a service with stringent data protection measures.

After extensively researching the online fax industry, we noted several basic features that are widely available and beneficial to most businesses. If you're shopping around for an online fax service, keep an eye out for these features in the average service plan:

• Intuitive interface: Usability is paramount in today's high-tech world, and online fax services are no different. Without an easily understandable interface, users are often left wondering if their faxes were in the right file format, included a cover letter or were even sent at all. An online fax company should offer an understandable web interface, with some also including mobile apps in the mix. If you can easily navigate a company's system, you will spend less time with customer support and more time getting your documents and messages where they need to go.
  
  
• Included fax number: Many of today's online services include a fax number, with the option to purchase additional ones on the side. While most online fax services can operate by email these days, a dedicated fax number allows others to easily send messages to your account through a traditional fax machine. Some companies offer to include or charge an additional fee for a toll-free, local or vanity number. Whether those specialty numbers are an important feature depends entirely on your company's needs.
  
  
• App support: Nearly everyone has a smartphone, so any company that provides a mobile app instantly gets a leg up on its competition. The ability to access your online fax account anywhere can be a major help if you and your employees are often on the go. Being able to scan and send faxes through a mobile device is also helpful for that purpose. When looking at this feature, make sure that the app supports your mobile device's operating system.
  
  
• Number of users: Some companies need more than one or two employees to access the online fax account. We found that only certain vendors offer group plans, which come at a higher premium.
  
  
• Electronic signature capabilities: Sometimes a digital fax needs to be signed before it can be sent. Being able to affix a signature to a digital file before transmission isn't a very common feature among the vendors we researched, but that capability supports one of the biggest benefits of the technology. Being able to sign a document online means you no longer have to print it out, sign it and scan it back into a digital format before sending it.

There are many reasons why you would want to sign your small business up for an online fax service. To better understand why some have made the switch, we sought out and discussed the topic with individuals from companies that have done so.

For Ryan Turner, co-owner of 3Prime Web Solutions, the decision to switch from a physical fax machine to MyFax came down to efficiency.

"Managing a traditional fax machine seemed ridiculous to us, and having to segment the phone number or, worse, get a dedicated line seems wasteful," he said.

Though he is considering looking into a different service since his business doesn't send as many faxes as it used to, Turner said his company has "never had an issue with [online fax]. We create documents and upload them to fax. It's much easier to work with than the fax machines I remember."

Similarly, Alex Kovalenko, director of IT recruitment at Kovasys, said the switch hinged on how much his company was paying for an extra phone line to operate a traditional fax machine. "We no longer need to pay a separate line for faxes, which would cost us around $40 to $50 a month, when online fax only costs around $10 a month."

While a cost analysis may prompt one company to make the switch, Burial Insurance Pro founder Matt Schmidt said ease of use and accessibility was important to his team's needs.

"Our faxes now come into our email system and can immediately be downloaded into our sales system," he said. "This also allows us to immediately send off the documents to the appropriate party, without any further scanning or downloading."

As these services reduce the need to purchase ink and paper, some environmentally conscious companies naturally make the switch to an online fax solution. Torben Lonne, diver and co-founder of online magazine DIVEIN.com, said his company has used RingCentral's fax service for years because of its lighter carbon footprint.

"The amount of paper generated by fax machines is completely unnecessary nowadays where we can digitize everything," he said.

What are the benefits of online faxing?

Perhaps the most touted reason to adopt an online faxing service is to reduce office costs. An office fax machine often requires constant attention. Regular maintenance, ink and toner costs, and dips in productivity as employees stand around a machine while they send or wait to receive faxes are eliminated when the entire process can be done online from a person's desk.

Fax providers often allow you to store your sent and received faxes online. For some businesses, especially ones with regulatory requirements for faxing, it can be a lifesaver to store messages digitally instead of printing out the documents and stuffing them in filing cabinets. Some service providers make the faxes searchable so you can easily find them later.

Companies looking to go green could also find online faxing beneficial, as each message is transmitted over the internet and stored in the cloud. With no need to print documents, there is less paper waste.

What is the difference between online faxing and regular faxing?

The biggest difference between online faxing and regular faxing is the removal of a dedicated piece of office equipment from the equation. Such machines can cost thousands of dollars, with additional costs in the form of paper, ink and toner replacement, and a dedicated telephone line for transmission. Online faxing, however, just needs an internet-capable device and a stable internet connection to send and receive digital files.

How do you send free faxes online?

While the best online fax solutions charge either a monthly or one-time fee to use their services, there are some ways to send an online fax for free. The easiest to consider are the free alternatives available online. In fact, we've reviewed a free incoming fax service as part of this section, so be sure to read our FaxBetter review to see why it's our best pick for free incoming faxes.

You are unlikely to find any free fax solution that lets you send faxes, since the action of transmitting a file requires more effort from a company's server than receiving a file does. Any company that says it offers its online fax sending services for free usually mean it offers a free trial, after which you'll be charged a monthly fee. If you find such a service, be sure to read the fine print before agreeing to anything. 

What should you look for in an online fax service?

The easiest answer to this question is "it depends." The faxing solution that will work best for you depends on how much you intend to use it and what features you require.

Good fax service providers feature a combination of three things: secure incoming and outgoing fax capabilities, an easy-to-use interface or integration with existing services, and stellar customer service. 

Can you fax through Wi-Fi? 

One of the benefits to using an online fax service is the need for less equipment. Rather than relying on a clunky piece of office machinery to send faxes through a land-based telephone line, online faxing just requires a functioning computer, a working internet connection, and the digital file or group of files you're looking to transmit.

While it doesn't matter if your internet connection is hardwired or transmitted via Wi-Fi, you should make sure your wireless connection is strong and consistent during transmission. Any interruptions in the sending or receiving process can cause transmission issues with the documents.

What are the different kinds of online fax services? When it comes to choosing which online fax service you want to utilize, it's important to consider how you want to send and receive faxes in the first place. Depending on the service, multiple methods can be available to you at the same time, largely depending on the devices you have on hand.

In most cases, services will be of the "fax from web" variety, which allow you to send and/or receive faxes through your internet browser. This method employs a web-based dashboard that houses your Inbox and your Sent messages folder, as well as a long list of settings that you can change.

In a similar fashion, some services offer email-to-fax or fax-to-email. This type of service allows users to utilize their email provider to send and receive faxes. Users that opt for this method generally send faxes by entering the recipient's fax number into the "To" field, with the service's website (e.g. @onlinefax.net) at the end of the number. If someone wants to send a fax to you though this service, they will do the same, entering your fax number and service provider's domain name into the "To" field.

Some of the more modern services allow for mobile online faxing. With this style, you can use your mobile device as a de facto fax machine. This usually requires an app so you can send and receive faxes anywhere.

There are some rare cases where an online fax service can provide a device to act as a bridge between your office's existing fax machine to the internet. With that device installed, your online faxing capabilities still eliminate the need for a dedicated land-based telephone line but keeps your existing equipment intact.

How does email-to-fax work?

One of the more common features among online fax services is the ability to send a fax through an email client. While some details vary depending on the service you're using, there are some commonalities.

When sending a fax, you attach a document or file to an outgoing email and send it to a predetermined email address attached to your account with the online fax provider. That address is usually your recipient's fax number, followed by the "@" symbol and the service provider's URL. (e.g., 8752348341@onlinefax.net) Once you click Send, the provider takes that information and sends it to the fax number selected as the recipient.

If you are receiving an emailed fax, the online fax provider takes the incoming fax, converts it to an email-friendly message or attachment, and sends that information to your email inbox.

Do you need any additional equipment for online faxing?

In nearly every instance, the only equipment needed to utilize an online faxing service is a computer with a modern internet browser installed and an internet connection.

Some services offer additional equipment to connect existing fax machines to the online fax service. These devices connect directly to your fax machine and internet connection. Users who are more familiar with the traditional fax machine can still take advantage of online faxing.

When does it make sense to switch to an online fax service?

The answer to this question often hinges on cost, available office space and accessibility. While the cost of purchasing a fax machine may no longer be a factor in your office's daily operation, the cost to replace paper, ink, or toner, and regular maintenance, can add up over the years – which doesn't exist with an online fax service.

For a small business, available office space is also a major consideration. Smaller workspaces are cheaper than larger ones, but if you have limited room for a fax machine, that's space that can be better used for other equipment (or purposes). With online fax services, you can minimize the amount of equipment you have to purchase and maintain, plus you can read and send faxes from any compatible device, while traditional faxes require a printed page, which comes with some degradation in quality.

How do you choose the best online fax service?

The answer to this question is highly subjective. If your business needs to only occasionally send or receive a fax, then you should consider a service that charges on a per-use basis. If you need something a little more consistent, then a service with a monthly subscription will be best for your small business. Companies that need to keep their data safe and secure should consider an online fax service that offers strong data protections. To that end, you want to find a company that also caters to healthcare providers and other institutions that handle sensitive documents.

In all honesty, you can choose the best online fax service by considering your business's needs and looking for a company that can fill those needs. Price, reliability, security and functionality should factor into your decision.

Do you need any additional devices to use an online fax service? In most instances, if you have a Mac or PC that's connected to the internet, you are good to go when it comes to using an online fax service. Most services simply need an internet browser to operate. In special cases, however, some services let users download apps to their phones to send and receive faxes, while in some cases, a service can sell a special bridge device to allow legacy faxing equipment to connect to the online fax service.

We researched several online faxing vendors, including their plans and features. We began by compiling a list of vendors. In addition to the service providers we were already familiar with, we added vendors we found in our research, those that regularly appeared on other reputable online lists and reviews, and companies that reached out to us asking to be considered for review.

Next, we went to each vendor's website, noting their features and pricing structures. When available, we took advantage of trial periods, watched product demos and tutorials, and sent sample faxes to gain firsthand experience of the service. We eliminated companies whose plans contained lots of hidden fees and/or that charged exorbitant over-limit fees.

For the next phase of our research, we reached out to our finalists, posing as a potential customer. We posed a series of questions to customer service reps from each company, noting the quality of service we received.

To arrive at our final determination, we considered which companies offered the best balance of affordability, robust features and ease of use. Here are the criteria we used to evaluate each online fax software provider:

• Pricing structure. We looked for faxing services that offered a variety of plans, making them accessible to businesses with a range of faxing needs and budgets.
  
  
• Fax limits and overage fees. In nearly every instance, vendors offer multiple plans with different limits regarding the numbers of pages a user can send or receive. The higher the service tier, the more frequently faxes can be transmitted. Along with the page limit, nearly every company charges an overage fee if more faxes are sent or received than the number allotted in the plan.
  
  
• Features. We specifically looked for features that make it easier to send and receive faxes, such as scheduled delivery, electronic signature, the ability to edit documents, the option of sending faxes to multiple recipients simultaneously and integration with modern software suites.
  
  
• International and toll-free faxing. Around the world, faxes are still used. Some fax services will sell you a fax number in a foreign country; most services, though, let you send international faxes for a small fee. Many services offer toll-free faxing, which is an added bonus for your clients and customers if you frequently fax documents back and forth.
  
  
• Mobile access. Most business people never go anywhere without their cellphones. We sought out services that either offer their own mobile app or allow users to send and receive faxes through a web browser.
  
  
• Ease of use. In addition to convenient features and fair pricing, we prized services that had an simple, intuitive interface. We relied on product demos and trial versions to determine how easy it was to send and receive a fax.

One major trend in the online faxing industry is consolidation. J2 Global has acquired more than a dozen online fax brands. During our research, we came across numerous consumer complaints about unfair billing practices, poor customer service and almost scam-like practices, which have led to J2 Global and its holdings receiving an F rating from the Better Business Bureau. Customers report similar problems on Consumer Affairs and the Complaints Board.

While some of these subsidiary companies are listed below on our vendor's list, in each case, we have noted their parent company and eliminated them from consideration as a best pick.

If you're considering using one of these services, carefully research whether or not the company is the best option for your business.
