Top Online Fax Services

The best auto insurance companies have more than just competitive prices; they also offer versatile coverage options, superior customer service, a solid financial report, and an excellent shopping experience. We researched all of those factors and discovered that only four of the nation’s biggest insurers really fit the bill and are good enough to recommend to family and friends.

Online faxing allows you to quickly and securely transfer documents from anywhere that has an internet connection. To find the best online fax services, we researched nearly 40 companies and sent dozens of faxes with the top contenders to test their accessibility, convenience, customer service, and all-around ease of use.

Our Best Overall Winner - HelloFax

We immediately liked HelloFax’s uncluttered, friendly site. It was easy to navigate, and sending and receiving faxes was a breeze. The process was intuitive, partly because of the encouraging popups explaining what to do and what to expect next. We were able to create a free account and send off a fax without reading any instructions in under five minutes. For most people, whether just faxing one page or thousands, using HelloFax will be easier and more enjoyable than any other online fax service.

Of all the online fax services we tested, HelloFax had the cleanest, most user-friendly interface for uploading documents. All of the icons for its supported third-party cloud storage options (including Google Drive, Dropbox, Box, Evernote, and OneDrive) are located in one obvious toolbar at the top of the page, and allowed us to easily fax documents that would otherwise be too large for email. Other contenders, like FaxNgo, didn’t have a way to easily and quickly navigate to a cloud storage service, even though they were technically integrated.

In addition, HelloFax offers the ability to easily annotate faxes before sending them. The option is built into the sending process, and it’s included in both the free and paid versions of the service; no other free plan offers this. Most other free plans are provide only super-basic functions (e.g., you can only add your signature to a fax and send it).

Another neat trick HelloFax has built in: the ability to add a link to your fax, which your recipient can visit for a full-color and high-resolution version of your document.

The downsides: HelloFax doesn’t have a mobile app and their customer service isn’t instantaneous. We received helpful responses to all of our questions well within 24 hours, which pleasantly surprised us, but the file-a-ticket-and-wait system still isn’t great.

If the lack of customer service doesn’t freak you out, HelloFax’s paid plans are less expensive than our other top pick, eFax. With the “Home Office” plan (conveniently part of the same suite as HelloSign, which allows you to make legally binding signatures electronically), you can have five team members and send or receive 300 total pages per month for $10, instead of paying about $17 for the equivalent plan with eFax.


Runner Up - eFax

By the numbers, eFax was the top-scoring online fax service in our test. While not as user-friendly as HelloFax, it still aced our evaluations on its level of accessibility and its quality of customer service. If you’re using an online fax service as a part of your small business and need quick solutions to any faxing problems that might arise, or if you need to fax regularly and travel often, go with eFax.

We especially liked that eFax has customer support available 24/7 live chat, phone, or online ticket. Most of the other top contenders’ customer service departments were only open during regular business hours and only RingCentral and MyFax also offered all three ways to get in touch. That’s not to say eFax’s customer support is perfect: when you call, you’ll talk to a slightly annoying robot for a few minutes before you get to talk to a person. That person is likely to be courteous and helpful, but also in a hurry. (We called twice and spoke with different reps, with similar results.)

We liked the added convenience of being able to fax on the go via eFax’s mobile app.

Like HelloFax, eFax offers the ability to share files too large for email (not all services do), fax documents directly from third-party cloud storage services, and sign documents electronically. There are also highly rated apps available for eFax on both Android and iOS (3.5 stars and 4 stars, respectively), which allowed us to do everything that the web browser-based interface did, including signing and annotating documents, as well as archiving them in the cloud.

The eFax monthly paid subscription is $17 per month, has a limit of 150 pages sent/150 pages received, and, like HelloFax, allows you to connect up to five email addresses to the account. If you need to include more team members or require a higher volume of faxes, you’ll have to move over to eFax Corporate, which touts higher levels of encryption, and HIPAA compliance. Quotes vary for eFax Corporate subscriptions based on the size of the company and the volume of faxes required.

eFax offers a free 30-day trial period before kicking into an automatically renewing monthly subscription. The company also has a free, bare-bones plan with a limit of 10 sent fax pages per month, that’s hardly advertised on the eFax site. There’s no option to include an electronic signature, but it’s a solid choice if you rarely fax, and don’t need to sign or receive faxes.

The FAQ section on eFax’s site impressed us more than most, too. It covered just about everything we could possibly want to know about online faxing through its service, and provided clear organization (including tutorial-style infographics). Using these self-help reference tools, you may never need to call support.
