7 Best Online Fax Services for a Mac

Of every service we tested, Municorn Fax delivers the smoothest and most intuitive Mac experience. As the highest-rated and most popular faxing app on the App Store, it benefits from a setup flow that uses your existing Apple ID — no new account or extra password to remember — and a native interface that feels at home on macOS.

The send flow shows a helpful summary page before transmission — fax pages, recipient number, and cover page all visible from one view — which we found reduced the kind of “did I attach the right file?” anxiety that plagues some of the web-based competitors.

The Apple-friendly design is one thing, but the quality of the service is what cemented its position at #1. No other platform we tested could capture our brochure PDF in better detail — text, images, and graphics all transmitted in HD-grade clarity. If you need to send documents via fax with the best clarity, this is the service to use.

On value, this is also the only service on the list that offers a truly unlimited fax plan as standard — international faxing included (most others charge extra by destination), and no page limits. There are weekly, monthly, or annual plans to choose from.

Customer support is another win — in-app live chat is available, and the service offers full HIPAA compliance and end-to-end encryption (something your email service won’t give you). It also retains the conveniences of email: upload as many files as you need to attach to a fax, and the app converts them into fax pages. The app keeps a log of all sent and received faxes, even backing them up for free in case you lose your device.

Overall, if you’re looking for a way to get the most out of your hardware and fax from Mac with minimum hassle, Municorn Fax is our top recommendation.

EveryFax works from any email app or browser on Mac — both options are included as standard, so all you need is an internet connection.

The standout for EveryFax is the web interface itself — it’s as intuitive as any app you might download, and compared to alternatives on this list such as Fax.Plus, EveryFax just feels more polished, cleaner, and slicker. Small touches like the country flag next to each fax number reflect a level of design care that the competition lacks. The layout and color palette of Fax.Plus reads more “Windows XP” by comparison; EveryFax looks and feels more like Apple’s latest operating system.

The small speech bubble in the bottom right of EveryFax’s menu opens a chat window where you can either contact customer support or connect to an AI agent — and crucially, you can try this on a free account, before signing up to a paid plan, which most competitors don’t allow.

The other standout is value. EveryFax’s basic, lowest-cost subscription doesn’t charge extra for international faxes — most other faxing services charge a high premium for faxing abroad. Its mid-range plan also includes unlimited faxing at a lower price than other services on this list that limit users to as little as 500 pages. On average price per page, EveryFax and Municorn Fax are the clear winners on this list.

EveryFax also offers Team and Business plans, plus an Enterprise tier for larger deployments — making it a fantastic option for business users on Macs who need to stay productive even when they’re not in the office.

Having sent over 20 million faxes, iFax is a highly trusted online fax service for Mac owners. iFax has a Mac app but can also be used via web browser or, at extra cost, email-to-fax. The web browser delivers the best experience due to the number of features only available there.

On features, iFax brings more than any other service on this list: custom cover pages, scheduled faxes, AI support, smart templates, document annotation and signing, automation, and a color-coded dashboard for fax management. If you’re serious about faxing and don’t mind spending more, iFax has more to offer than its competition.

iFax does not include an unlimited faxing option, unlike the two services above. It also has a quality system where users spend more pages (you get a fixed allowance per month) to upgrade a fax to HD or HD+ — paying more, in effect, to ensure higher quality. We tested this and it didn’t work very well: HD (2 credits per page) was by far the worst option, and HD+ (3 credits per page) wasn’t as good as the standard quality of competitors. The image below shows our test results across the three quality tiers.

This leads to the value concern. iFax is expensive: to use email-to-fax, you have to subscribe to the highest individual plan available — the ‘Pro’ package at $39.99 per month — which still limits your pages. EveryFax and Municorn Fax will give you fully unlimited worldwide faxing for less than this, representing a better deal for most Mac users.

There’s also a lot of upselling. The web menu shows you the full Pro functionality even when you’re not a Pro customer, and clicking on any ‘Pro only’ feature triggers an email — every single time. We hit multiple emails per minute while navigating the menu, which got old quickly.

Customer support, however, is genuinely outstanding — you get what you pay for. iFax offers new customers a free video call to walk them through full usage, and a phone line and live chat are accessible to subscribers at any time. iFax is perhaps the best option on this list for support specifically.

Fax.Plus is a Mac-friendly web faxing and email-to-fax service. It also has a downloadable Mac app, but as it’s not verified for macOS, we don’t recommend that route.

Fax.Plus has a strong feature set, second only to iFax on this list — scheduled fax, cloud storage integration, dedicated apps for signing and scanning, and an “optimise for image/text” toggle when you send. We tested the optimise toggle and found absolutely no difference between the resulting faxes, so that one’s a marketing feature more than a working one.

Where Fax.Plus beats iFax on value: email-to-fax is included in the very cheapest plan on Fax.Plus, while iFax locks it behind the top tier. Other Fax.Plus features are walled off, however — even the ‘Business’ package at almost $40 per month doesn’t include document signing, which costs extra via Sign.Plus. HIPAA compliance is only available on the $100-per-month plan, whereas competitors include it on basic plans.

For fax quality, Fax.Plus is above average — clear and readable, but not at the level of the top services. Comparing our test results to Municorn Fax, it preserved more light and detail on the back of the couch and on the map; Fax.Plus is still solid against most of the rest.

Fax.Plus offers a free trial of up to 10 faxes before purchasing a subscription. Value is generally strongest at the lower price level — it’s a better choice than iFax for budget-conscious users and a great choice for Mac owners who don’t fax often. iFax does pull ahead on advanced features and including more services in higher-priced subscriptions.

Dropbox Fax (formerly HelloFax) is a built-in service for Dropbox, allowing users to send and receive faxes through their regular account at a small extra charge. For Mac users, this works over the web or via email-to-fax using the address registered to the account.

Fax quality is the first thing to flag — Dropbox Fax doesn’t match the dedicated services. Dropbox is first and foremost a document storage service, so the fax-quality drop is unsurprising. Compared to a top service like Municorn Fax, the difference in clarity and color shading is visible on the logo, the large photograph, and the map below — Municorn Fax captured far more detail.

Dropbox Fax mitigates this by offering a high-resolution color option — the recipient is sent a link to access a higher-quality version of the scanned document on the Dropbox website. It’s a workaround, not a fix.

Customer support is the other concern: no live chat, barely any FAQs, and the only way to contact support is through a form on their website. The TrustPilot reviews on Dropbox Fax are very negative, which echoes our own experience.

Still, Dropbox Fax is genuinely easy to use on Mac for users already in the Dropbox ecosystem — particularly with the document editing and signing features included on every subscription level. Value overall is strong compared to iFax or Fax.Plus: 300 pages per month at $10/month, with email-to-fax and document signing included, is one of the better deals on this list.

eFax is a longtime favorite online fax service for businesses and corporations, with specialised support for the healthcare and finance industries — but it also offers individual Mac users the ability to fax via web, email, or mobile app. Its enterprise pedigree is a real advantage on the quality and reliability axes.

The interface is intuitive and Gmail-like, which we found made everyday use comfortable. eFax includes basic features like signatures and contacts, plus email-to-fax as standard (unlike iFax). For advanced functionality and customer support, however, iFax and Municorn Fax offer more.

Fax quality is among the best on this list, which we’d expect from a company that runs faxing services for Fortune 500 companies and operates a number of specialist faxing apps under its umbrella.

The value for individual users is the soft spot. The ‘Pro’ option only includes 150 pages per month and costs more than Fax.Plus’s 200 pages or Dropbox Fax’s 300 pages. Another small but persistent annoyance: eFax constantly logs you out on the website, which made our testing sessions far more friction-heavy than they needed to be.

The fax quality is much worse than any paid service we tested — our brochure lost most of its detail, the map became unreadable, and the icon next to the phone number disappeared entirely. For anything important, sensitive, or visually complex, this isn’t a viable option.

If you’re specifically looking for free fax options, our free fax services review covers the full landscape, including GotFreeFax alongside FaxZero and others, with quality tests and security caveats for each. For most Mac users on this Mac-specific list, one of the paid services above will deliver dramatically better quality and security at a low monthly cost.
