The best online fax services provide a simple way to use secure cloud-based fax-to-email services, without requiring a fax machine.

Fax machines (opens in new tab) still remain common in many offices, but the best online fax services have given physical machines a run for their money in recent years with a cloud-based alternative. This involves sending an email to be printed out by a fax machine at the end of the fax number.

While fax technology may seem a little outdated to some, it does offer the advantage of security, as well as providing print communications directly so they can be read rather than forgotten in someone's email box, and then printed anyway.

The result is that faxes are still very much alive in the modern business world, and remain an essential tool for many businesses and other organizations – in particular for transactions that require a signature such as legal contracts or real-estate deals.

In this article, we’ve looked at the best online fax services, evaluating their respective features and factoring in costs to pick out the best offerings for your small business.

Best online fax for small teams

Reasons to buy

+
Free tier
+
Small team plan
+
Slack integration

Fax.Plus is an online fax service that offers cross-platform flexibility and a mobile-friendly interface. Even though it's an online service you can keep your normal fax number, and you can be assured it's secured through compliance with HIPAA and PCI protocols. The service is built to be easy to use, and faxes can be signed at the touch of a button. 

A free tier allows up to ten pages a month, but that's only for sending and there's no option to receive, and is only recommended for light users and individuals. Paid plans include 100 pages with each additional page charged per page, though it does include the ability to use electronic signatures.

The Business tier is good for small teams of up to 5 members, and also allows you to export fax logs as CSV files. There's also an admin panel for team management and Slack integration for communications. Up to 800 pages per month are provided within this plan, with anything over charged per page.

Apply a signature to a fax from within app

Faxburner adopts a ‘Mobile first’ approach, with apps available for the iOS and Android platforms, that work on both smartphones and tablets. Users can start with a free account, which comes with a temporary fax number, that expires after 24 hours. After that, FaxBurner gives the option to keep the fax number by upgrading to a paid account. There is absolutely no need for a dedicated phone line, or even a physical fax machine.

FaxBurner's free version has a disposable fax number which expires after 24 hours. It also has a reasonable volume of 25 pages of inbound faxing, and 5 pages of outbound fax also. It also includes email-to-fax support, and fax-to-email support.

Faxburner's Professional plan includes multiple upgrades, including notably a permanent fax number, a toll-free number, as well as the lower plan’s email-to-fax support, and fax-to-email support. The page limit goes up to 500 pages monthly total limit, that covers both inbound and outbound faxing.

The top tier Premier plan includes all the features of lower plans, with the increase of total inbound and outbound fax pages of 2,000 for each month.

Faxburner stands out from the competition with a usable free tier, and less restrictive, higher page limits than their competitors in the paid tiers. Their app provides additional functionality, such as the ability to receive, sign and send documents, all from a mobile platform.

The best online fax provider

Unlimited accounts

Comprehensive options

API integration

Emphasis on security

Faxage is an impressively comprehensive online fax service that allows users to both send and receive. While it’s not especially cheap, this provider stands out for offering an unlimited number of users on every account and a wealth of administrative features. 

Faxage includes a number of useful features with every plan. To start, you can add an unlimited number of online accounts to any plan, including plans marked for individuals. That’s a huge advantage for small businesses.

Faxage also makes it very easy to send faxes. You can create new faxes through your online account and attach any documents (opens in new tab) or images from your computer. Alternatively, you can send faxes directly from your email (opens in new tab). Windows users also get access to the Faxage print driver, which enables you to send a fax right from most Microsoft Office (opens in new tab) programs.

Another big plus for Faxage is that all accounts get access to the API. This system enables you to integrate sending and receiving capabilities into your existing workflows. Faxage also puts more emphasis on security (opens in new tab) than many of its competitors, using SSL and TLS for every fax sent from either the web-based interface, the API, or your email.

Best online fax service for sole proprietors

Reasons to buy

+
Call center platform
+
Omnichannel communications
+
Many integration options
+
Flexible solution

While some of the best online fax services are standalone, RingCentral Fax can work in that way, or as an integrated part of its call center platform.

The RingCentral Fax service is cloud-based so it takes minutes to set up, and that also means that you can access it from any device using a web browser or mobile app. 

One of the biggest advantages of the RingCentral Fax services isn't just the pricing, but the fact that it can be upgraded to use the RingCentral call center platform. This means enjoying all the advantages of all-in-one and omnichannel communications, so you can easily switch between fax, phone, email, text, and social media messaging to maintain your contacts with business partners and customers.

Additionally, the RingCentral call center is a powerful platform with a host of available integrations, not least with Salesforce, Google, Amazon, and Microsoft. This makes it an incredibly versatile solution to work for your business.

The fax service itself has two different pricing levels. The Fax 1500 plan offers up to 1500 free faxes per month and charges per fax after, while also including cloud storage integration with Box, Dropbox, Google Drive and Microsoft.

The simple online fax service

Reasons to buy

+
Receive faxes for free
+
Affordable plans
+
Advanced fax search

FaxBetter has a very simple interface that at times looks too basic, but it's also an online fax service that offers the ability to receive faxes for free, something we have yet to see from any serious competitors.

There's a complete record of your sent and received faxes in your dashboard, and though you can't drag and drop faxes to categorize then, you can select multiple documents to tag them with a label or delete them from your inbox. The ability to search your fax history also includes being able to search for text within a specific document.

Generally, though, FaxBetter is functional rather than brilliant as a service. It does what it needs to do well enough, but it lacks the more advanced features that competitors offer.

On saying that, pricing plans reflect this which makes FaxBetter ideal for anyone who doesn't need all the extras that other online fax services offer, and just needs a simple but reliable fax service.

Also consider these online fax services

Narrowing down our list of the best online fax services proved tricky, so here are some additional notable mentions.

Metrofax (opens in new tab) is a good online fax provider if having a mobile app and 24/7 support is important to you. But, it doesn’t emphasize security and the features could be more robust.

Hellofax (opens in new tab) is a great online fax provider if you value integration with your cloud storage spaces, security, and privacy. But, plans are expensive compared to HelloFax’s competitors.

Gotfreefax (opens in new tab) stands out for enabling small business users to create prepaid accounts. While we’d like to see more file types supported, we also like that you can upload up to 10 files per fax. 

FaxZero (opens in new tab) is a great choice for sending an electronic fax if you only need to send documents on occasion. The interface is extremely simple, and the service is inexpensive even if you can’t take advantage of the free faxing option.

iFax (opens in new tab)  is good for sending and receiving faxes across the globe at a reasonable speed, using any device, desktop or mobile. It offers many useful features like email-to-fax, HIPAA compliance, and the use of toll-free fax numbers.

Which online fax service is best for you?

We’ve highlighted five key points to bear in mind when picking the right online fax solution to suit your needs.

1. Archiving of documents

Yes, we are all still waiting for the paperless office we were mistakenly promised decades ago. However, we are slowly inching our way towards it, with the digital archiving of documents. With an online fax service, the faxed documents, rather than being on paper, are automatically digitized. Furthermore, some fax services offer digital archiving, so as long as you stay with the provider, all of your sent and received faxes will be available in an online database, giving you a neat storage solution.

2. Integration with cloud storage services

Cloud storage is an important business tool these days. Using this, you can not only archive existing files, but also create new documents with the likes of word processing and spreadsheet apps built into the service (just look at Microsoft’s Office 365 or Google’s G Suite, which are quickly becoming business essentials).

Therefore, look for an online faxing service that easily integrates with these cloud solutions to enhance your workflow, making creating and then faxing documents a seamless process.

3. Multi-platform support

Most online fax services have mobile apps (iOS and Android) for use while on the move via a smartphone or tablet. Also look for a service that has software to support desktop platforms as well, as who wants to use their smartphone for a business task when sitting in front of their desktop computer?

4. Higher page limits

Page limits are a significant downside of some online fax services. Be sure to adequately estimate your needs in this respect, and look for plans that count the monthly total, and don’t divide it up into send and receive categories (which could feasibly cause you to go over the limit without realizing).

In short, look for a plan offering an appropriate amount of pages, and a reasonable page overage fee. Also look for a service with multiple tiers – including an unlimited one – so there is no danger of your business outgrowing your fax service.

5. Availability of fax phone numbers

While cloud faxing marries the fax to the internet, the forward-facing part of the fax service is the fax number. Better fax services allow for a greater number of options when choosing a fax number, and these include local, toll-free numbers, and even vanity choices.

There can also be options to have an international number located in a country that you do business with to give your company more of a local presence. Finally, there should be an option to port an existing fax number for an affordable cost.
