If you need to send a fax from your Mac, we’ve taken a look at the best fax software and apps for Mac in 2019.
Using fax software is by far the easiest and cheapest way to send and receive faxes from Macs as it avoids the need for fax machines, paper, modems or phone lines.
All you need is access to any email account.
Using fax software rather than a clunky old fax machine is also the perfect solution to help go paperless in your home or office.

If you’re in a hurry, below is a side-by-side shortlist of our top 3 picks although you’ll find other less reliable pay-as-you-go apps reviewed here too.

Here then is our list of the best fax software for Mac users in order of ranking.
If you want to send or receive faxes quickly, easily and cheaply from your Mac, you can’t do better than eFax.
eFax is easily the leading online fax service out there due to its ease of use, low cost, email fax sending system and handy mobile apps.
You get more features in eFax than any other fax service such as e-signing of photos and documents and the largest file attachment allowance in the industry (up to 1GB).
All you need is your regular email account to send faxes with eFax although you can send faxes via a web interface too.
You simply attach the faxes as attachments to an email, write your cover letter in the body of the email and send the email to the fax number of your choice followed by @eFaxSend.com e.g. 123725346346@eFaxSend.com.
You will receive faxes in the same email account that you send faxes from which is incredibly convenient.
Alternatively, you can log into your eFax account online and send them via the eFax web interface:
If you need to send large documents or files, eFax offers a 1GB attachment size limit which is far bigger than any other fax service (the closest rival RingCentral only offers 20MB).
This is essential when it comes to sending very long faxes or faxes with lots of images, graphics or tables in them as it increases the file size significantly.
eFax also offers the best mobile fax apps for iPhone, iPad and Android of any service out there. These are the only mobile fax apps to support swipe-signing of faxes which is useful for official documents that require a signature. Note however that like all fax services, eFax will not be able to sign a Business Associate Agreement.
You can also take a photo, sign-it and then fax it in a few swipes.
If you need to fax a document that’s not saved on your phone, eFax is integrated with online storage solutions such as Dropbox, iCloud, Google Drive and OneDrive so you can download them and send them easily.
The mobile app is also very useful if you need to send or check faxes when you’re on the move and away from your computer. You can easily see how many faxes you’ve got how many pages they are in your inbox.
Confidentially is a huge issue when using online fax services and eFax uses the most secure protocols available. eFax uses encrypted fax protocols to comply with HIPAA, SOX and other federal regulations. This level of security is becoming increasingly important in the wake of news that malicious faxes can actually allow hackers to hack into corporate networks.
eFax now has two monthly subscription plans – eFax Plus for $16.95 per month and eFax Pro for $19.95 per month. The only difference between these two plans is that you get 150 sent and received faxes per month with eFax Plus compared to 200 with eFax Plus. Overage rates for pages beyond this are $0.10 cents per page.
eFax pricing is very similar to most other services but in our opinion, you get much more for your money. Exclusive features such as the ability to add electronic signatures for important documents, take and sign photos and a generous file upload limit are worth the cost alone.
Plus we like the fact that eFax is focused on fax only and does it well. It doesn’t try to upsell you office communication solutions like many of it’s competitors.
You can try eFax free for 30 days and cancel at anytime if you’re not satisfied.
Price: $16.95-$19.95/m- 30 Day Free Trial – No Setup Fee
RingCentral is the biggest rival to eFax although it’s designed as more of an all round communication suite than just for faxing.
While eFax focuses on just faxing, RingCentral offers phone, video conferencing and faxing in one making it a suitable alternative to Skype for Business on Mac.
RingCentral allows you to send and receive faxes from your computer, gives you a dedicated fax number and allows you you to send and receive faxes via e-mail. If you want to fax multiple contacts, you can create Groups in exactly the same way as you do with a group email.
RingCentral is integrated with online storage services such as Google Drive, DropBox, Box and Microsoft Outlook meaning you can conveniently fax documents stored in them from the main web interface.
If you need to upload large attachments, RingCentral only supports up to 20MB attachment file sizes compared to eFax’s 1GB.
You can add additional fax numbers to your plan for an extra $4.99 per month and add additional 800 or vanity numbers for a one time fee of $30.
One thing we really like about RingCentral is that is has its own Mac desktop app. Although this is basically the web interface on your Mac desktop, it’s nice to have it on hand in the Dock.
Like eFax, RingCentral also offers a mobile app. You can also use the RingCentral companion mobile app for iPhone & iPad, Android and BlackBerry from which you can send and receive faxes.
RingCentral pricing plans are very similar to eFax starting with the basic RingCentral 750 plan starting at $12.99 per month.
Phone support is not included in this though and you need the Fax 1500 or above to get phone support included.
Be aware that there is a difference between RingCentral Office and RingCentral Fax. RingCentral Office plans are more expensive as they are for the all in one office communication solution so make sure you don’t subscribe to the wrong one.
Price: Starts $12.99 Month – 30 Day Free Trial – No Setup Fee
Like RingCentral, nowadays Nextiva is an all-in-one office communication solution with VoIP phone, Service CRM and even an Email Marketing Software.
However, you can just choose to subscribe to Nextiva Fax.
Like the other fax platforms, Nextiva allows you to send and receive faxes via email or your mobile device.
The web interface is very clean with a simple dashboard which helps you manage sent and received faxes.
You can choose to either send and receive faxes via this portal by clicking “Send A Fax” or setup an email account to associate it with via “Fax Settings”.
Sending a fax via the portal is simply a case of adding a fax number and details about who it’s from and when to send it.
You can upload documents in most major formats such as PDF, DOC, PNG, JPG etc. You can also choose to send a copy of the fax to an email address if you want to have confirmation of it.
Sending via email is even easier. All you have to do is to send the email to the fax number by prefixing the number with a “1” and adding @nextivafax.com.
Note that Nextiva has the smallest file upload limit of our top picks though allowing just 5MB and a maximum of 10 attachments at one time.
For small businesses, the $12.95 per month package supports 1000 sent and received pages per month which is pretty generous. For bigger businesses, you can send up to 3000 pages a month with the Business Pro plan for $29.95 per month.
You also have to pay annually in advance for all Nextiva plans, you can cancel at any time and get a full refund.
Note also that Nextiva doesn’t support setting-up of toll-free fax numbers like eFax and RingCentral do.
You can try a free trial of Nextiva for 30 days.
Price: $12.95/m+ – 30 Day Free Trial – No Setup Fee
If you just need something for occasional faxing, FaxFresh may be for you.
There are several fax apps on the Mac App Store that claim to offer pay-as-you-go faxing but unfortunately we’ve found many don’t work well and offer shady support afterwards.
FaxFresh however seems to work better than most and offers a simple Mac desktop app to send faxes although you can’t receive faxes with FaxFresh.
There’s no sign-up process for FaxFresh and no subscription required.
FaxFresh only supports attachments in PDF format but is extremely simple and easy to use.
Once installed, just use the small uploader to browse to the fax you want to upload in PDF format and just click Pay and Send. To pay, you’ll be taken to PayPal so note that you’ll need a PayPal account in order to use it.
FaxFresh claims it uses military grade encryption to send all faxes and doesn’t store documents after sending.
You receive a confirmation email when a fax has been sent successfully although sometimes we found that there can be a frustrating delay in this. If a fax is not sent because of a problem or wrong fax number, you will not be charged which isn’t always the case with fax software like FaxFresh.
On the downside, there’s no fax preview, cover letter generator and no support for multiple pages (you have to merge them all together in a PDF basically). If you need to generate a cover page, we recommend using Instant Fax Cover ($4.99) alongside FreshFax:
You can fax 8 pages for $1.99 with FaxFresh and then it costs 25 cents per sheet beyond that.
Although FaxFresh supports faxing to over 100 countries, there may also be an extra surcharge depending on the country you want to send to.
Price: $1.99 For 8 Pages / $0.25 Per Page
The FaxDocument Mac app is the official Mac fax software of FaxDocument.com (owned by J2 which owns eFax) which allows you to send faxes either from your browser or from the FaxDocument Mac app.
FaxDocument is a pay-as-you-go fax app like FaxFresh but has a slicker interface. Note that like most pay-as-you-go faxing software, it’s only for sending faxes, not receiving them.
FaxDocument is very easy to use. You can drag and drop documents in PDF, TIFF, Word, Excel, PowerPoint or RTF format into the interface.
We like the fact that FaxDocument clearly shows you which faxes have been successfully sent and which have failed in the Log. It would be better if you could tag or label these faxes as they’re all listed by generic fax numbers but it still gives you peace of mind that the fax was sent successfully.
On the downside, the FaxDocument Mac app doesn’t tell you how much credit you have remaining so it’s very difficult to keep track of how many more faxes you can send. You have to log into the web version to check your balance.
We also found the support team can be slow to respond in case of problems and not very helpful when they finally do.
Faxes cost as little as 60 cents for unlimited pages or alternatively, you can buy a quota of faxes. For $19.99 you can send up to 25 faxes or send 50 faxes for $29.99.
Price: 60 cents per fax or $19.99 For 25 Faxes
SnapFax is another pay-as-you go fax service for Mac which has a basic Mac desktop app.
SnapFax supports sending to 69 countries around the world including the USA, UK and Canada. SnapFax supports drag and drop of PDF documents for faxing, Fujitsu ScanSnap support and push notifications when a job is completed.
Unlike most fax services on Mac, it also gives you an estimated time of how long it will take to send your fax.
There’s also a handy SnapFax mobile app which allows you to take a picture of a document, attach it and then send it from your iPhone or Android device.
Although the SnapFax app is free from the Mac App Store, you have to make in-app purchases in order to buy fax credits. Pricing for SnapFax starts at $1.99 for 4 faxes and goes up to 200 faxes for $49.99. The more credits you buy at once, the cheaper it works out per fax.
You can watch how to fax a PDF using SnapFax for Mac below:
Price: Starts at 4 faxes for $1.99
By far the easiest, most feature packed and reliable fax way to fax from Mac is eFax. You certainly get the most value for money with it if you’re a small business.
If you only need to send a fax a few times a year though, pay-as-you go apps such as FaxFresh and FaxDocument are the best we’ve tried but all such services can be unreliable. And crucially, they don’t allow you to receive faxes either.
Mac Fax Software Tips
- Online fax services like eFax are definitely the best choice for small businesses and those that need to send faxes from a computer regularly. They allow you to use e-mail to send and receive faxes, give you your own fax number and many offer much more such as extra fax numbers, document signing, mobile apps, vanity numbers and more.
- Subscription services allow you to both send and receive faxes on your Mac (or a PC) both within the US and internationally. With all subscription fax services, you get your own dedicated fax number that anyone in the world can use to fax you with. Some services such as eFax even allow you to select a fax number with the country code of your choice even if you don’t live in that country. This is very useful if you run a business with offices in different parts of the globe.
- Most services also require you to pay extra if you want to fax internationally and the cost will depend on their location so check with the vendor if you’re planning to fax abroad. If you want to setup a toll free fax number so that customers or clients can fax you at no cost, some services such as eFax and RingCentral support 800 or vanity numbers.
- Although all online fax services advertise the subscription cost per month, this price is discounted because you are charged annually in advance so check the small print. If you choose to be charged on a monthly basis, the monthly cost will be a few dollars higher than paying annually. If you over your monthly subscription quota, most services charge you anything from around 3-10 cents per page extra.
- All online fax services offer a 30 day free trial although note that many require you to enter your credit or debit card details first. However, if you choose to cancel your free trial, your card will not be debited when the 30 days expires.
- To fax from an online fax service, most allow you to either send faxes using an email account or by simply uploading the document you want to send in either Word or PDF format to your online fax account. Most services allow you to view and read faxes within your browser in PDF format although some require you to download them first before opening them. Sending via email is easily the most convenient way to send a fax from your computer or mobile phone. You can use your existing email client to email and receive faxes which are received either as an attachment or via a link.
- To send a fax via email, you simply compose an email as you would normally and in the address field, enter the country code and fax number of the recipient and then @eFax.com, @Nextiva.com, @RingCentral.com or whatever service you’ve signed up for. You can also turn a fax into an email on Mac using Preview in macOS which doesn’t require you to use any fax services.
- If you send via email, the coversheet will be the email subject heading and content in the body of the email. If you add attachments, they will be sent as separate pages. If you need a cover sheet, most online fax services provide their own but you can also find lots of free fax cover sheet templates for Mac and PC here.
- Some services like Nextiva also allow you to connect your physical fax machine or multi-function printer so that you can use the software as a hub for sending and receiving faxes from your Mac. If you’re interested in using a printer-fax machine, check out our guide to the top all in one printers for Mac.
- You might also notice a very close similarity between the interfaces and services of some online fax services. This is because the biggest online fax services are owned by the same group J2 Global. J2 Global’s most popular brand is eFax but it also owns others such as MetroFax, RapidFax and Fax.com. To make things a bit confusing, in the US, eFax also operates under the brands MetroFax, RapidFax and Fax.com but in the rest of the World, these are now amalgamated under the same eFax brand.
- Whichever way you choose to send faxes from your Mac, you should be very careful if you intend on sending bulk faxes from Mac or PCs. There are strict laws on fax advertising and spamming via fax.
Online Fax Services vs Pay-As-You-Go Apps
Online fax services are ideal for sending faxes regularly and for sending faxes via email. However, they all require signing up for a monthly subscription which is not very economical if you just want to send the occasional fax.
That’s where a desktop pay-as-you-go fax app that allows you to pay-as-you-go pay is more useful. Many such apps allow you to send faxes from your desktop or browser for a a few cents.
However pay-per-fax services don’t allow you to receive faxes and are very limited in features and functionality compared to online fax services.
They are also far more prone to problems such as failed faxes and technical issues and usually have very limited customer support.
Also, be very careful when selecting which fax client to download from the Mac App Store as there are some which simply do not work as advertised or are no longer working properly anymore.
Finally, there are a few services that allow you to fax for free from a Mac although they are very limited, usually insert ads and are often very unreliable. We certainly don’t recommend them for professional use.
You can also fax from your Mac by using a modem although this has become a lot more complicated now that Apple has dropped support for USB modems in the latest versions of macOS.
