The 6 Best Online Fax Services and How to Decide

Still, some people continue to use BlackBerry smartphones. Along those same lines, some businesses might still need to fax. And that’s ok.

The good news with faxing is you no longer have to put up with a bulky fax machine taking up space in your office. (That’s for the giant coffee maker, after all.) With the best online fax services, you can send and receive faxes digitally, which greatly simplifies the process.

Here are the services we recommend choosing from.

How to pick your online fax service

When comparing the best online fax services, here are some of the criteria we looked at. Focus on how well each of these meet your needs as you narrow down options.


Don’t fall into the trap of paying for more than you need.

If you don’t do a lot of faxing, you don’t want to be spending a lot of money. Some services personalize their offerings for lower volume through lower pricing tiers that place limits on the number of pages you can send each month. If you’re tight on budget, decide what you’re willing to trade off.

An additional aspect to look into is how much you’ll pay for international faxing, if you need it. Some services will provide you with an international phone number to receive faxes, which will be cheaper for global transactions.

Trial offerings

Some services let you try them out for free for a set period of time, which is a great way to figure out if the interface and feature set will actually fit your needs.

Make sure that the trial includes the features you really care about. If not, it never hurts to ask sales whether they can ⁠throw in any advanced features to try for free—they should be willing to bend to your needs.


For many businesses, especially as they scale, the main draw of online faxing is the ability to simplify and accelerate it through automation. For example, being able to:

  • Send a fax at a scheduled time
  • Send a fax to multiple recipients at once
  • Edit incoming faxes
  • Add electronic signatures

Of course, things can go wrong with automated services, so check reviews to see what customers think of the service’s technological capabilities and support.

Cloud storage

If you pick an online fax service that stores copies of all your faxes in the cloud, you can access your documents from anywhere. This might be a deal-breaker for some companies.

Keep in mind that some services may limit the amount of storage space you receive, so think about how much you’ll need in the near future (or how easily you can upgrade storage limits) before committing to a plan.

Customized cover sheets

Depending on your chosen service, you may be able to create your own cover page for sending faxes. This can be a nice touch, allowing you to add additional information or branding to make your faxes look clean and professional.

Data encryption

If you’re looking to send and receive any faxes containing sensitive information, you will want the ability to encrypt it. Not least if you have guidelines like HIPAA to meet.

Mobile capabilities

Does your office spend a lot of time working remotely? Do employees need to be able to receive faxes on the go? If so, pay particular attention to the service’s mobile capabilities: its ease of use, whether it includes all the features you need to be able to access remotely, and how well the app is developed and supported.

Ideally, the app is intuitive enough for employees to get on board and comfortable immediately.

Search capabilities

With some online fax services, you get the ability to search stored faxes. This is a very helpful feature for businesses with large volumes of faxes to reference. Make sure your chosen service includes strong search capabilities like keywording and filtering.

Why fax online?

I can’t stress enough that it’s important for all employees to be on board with your chosen service, for it to be a hit. So in case they need convincing…

Online fax services give you so many benefits that it really makes no sense to park a bulky fax machine in your office any longer. You won’t be spending money on ink, toner, or paper for faxes that don’t need printing. You don’t have the extra expense of a hardwired phone line for faxing, either.

Online fax services also work faster than traditional fax machines, while ensuring the security you need without you having to worry about it.

With all these benefits, it’s easy to see why faxing is becoming a popular option again. You’ll want to have this type of service available for customers or vendors who need it.
