Best Faxing Apps in 2026
We compare #Fax, FAX.PLUS, eFax, and iFax on price, page limits, and HIPAA support so you can match a fax app to the way you actually fax.
Faxing refuses to die. Hospitals, law firms, insurers, and a surprising number of government offices still ask for a fax in 2026, and if you’re reading this, someone has probably just handed you a fax number and expected you to have a way to use it.
The good part is that the fax machine is the one piece you can skip. Every app below turns your phone or laptop into the sending end of a fax line. The reason there’s no single “best” is that these tools are built for genuinely different people: someone sending one insurance form has almost nothing in common with a clinic that needs a HIPAA agreement on file.
So this isn’t a “app #1 wins” list. It’s four solid options and a plain description of who each one is actually for.
The short version
Quick answer
Need to send a document from your iPhone today? Start with #Fax - it's the least fussy. Need to receive faxes, run a team, or sign a HIPAA agreement? Look at FAX.PLUS, eFax, and iFax instead, and check which plan actually includes what you need.
Quick picks
If you only read this far, here’s the gist.
iFax
If you need a HIPAA-ready plan without jumping to an enterprise contract, iFax gets you there sooner.
| App | Best for | Where it starts | The catch |
|---|---|---|---|
| #Fax | Quick sends from an iPhone, iPad, or Mac | Free for your first faxes | Built for sending, not a full team dashboard |
| FAX.PLUS | Teams that also want web and email-to-fax | $6.99/mo (Basic, 200 pages) | HIPAA + BAA only on the $79.99 Enterprise plan |
| eFax | Higher volumes and international faxing | Personal plan, 200 pages/mo to US & Canada | $0.10 per page once you go over the allowance |
| iFax | HIPAA-bound work without an enterprise deal | $12.49/mo (Basic, no HIPAA) | HIPAA starts on the $24.99 Plus plan, not Basic |
Best for a quick iPhone send
#Fax
#Fax does one thing and doesn't ask you to learn a business tool to do it: pick a document, type the fax number, send, keep the confirmation.
Reach for #Fax when
- You have a form, a signed page, or a PDF and you just want it gone.
- You'd rather not print anything or hunt down a machine.
- You want to start free and only pay if you keep faxing.
Where it stops
#Fax is deliberately narrow. If you need shared inboxes, a dozen user seats, or a fax API wired into other software, that's not what it's for - one of the platforms below will suit you better.
Best for teams
FAX.PLUS
FAX.PLUS is the one to beat if more than one person needs to fax and you want it to work the same on the web, on a phone, and straight from email.
Reach for FAX.PLUS when
- Two or more people share the faxing, or you want one audit trail.
- You'd use email-to-fax or send to several recipients at once.
- You want predictable monthly page limits, not per-page surprises.
The pricing detail that trips people up
Paid plans run from Basic at $6.99/mo (200 pages) up to Enterprise at $79.99/mo, and there's a free tier capped at 10 pages total. The catch for healthcare: FAX.PLUS only offers HIPAA compliance and a signed BAA on the Enterprise plan. If you're on Basic or Premium expecting HIPAA, you don't have it.
Checked on the FAX.PLUS pricing page.
Most established
eFax
eFax has been doing cloud fax since before "cloud" was a marketing word, and it shows in the page limits and the reach.
Reach for eFax when
- You want a name that's been around and isn't going anywhere.
- You send in volume - the Personal plan includes 200 pages a month to the US and Canada.
- You fax internationally; the Business plan opens up 500 pages across 51 countries.
Watch the overage
Go past your allowance and eFax bills per page - $0.10 on Personal, $0.07 on Business. For a light sender that's harmless; for a heavy month it adds up, so match the plan to your real volume.
Page counts and overage confirmed on the eFax pricing page.
Best mid-tier HIPAA
iFax
iFax leans hard into healthcare, and its advantage is where the HIPAA line sits: you don't have to negotiate an enterprise contract to get it.
Reach for iFax when
- You handle protected health information but you're not an enterprise buyer.
- You want the same account on a phone, Windows, and Mac.
- You need to receive faxes as well as send them.
Mind the tiers
The $12.49/mo Basic plan (200 pages) does not include HIPAA - that starts on the $24.99/mo Plus plan, which also adds a fax number. So if compliance is the whole reason you're here, budget for Plus, not Basic.

The four things worth checking before you pay
Scan quality
A fax is just a page image. If the app's scanner produces dark or crooked pages, the recipient gets an unreadable fax - test it on a real document first.
Proof it went through
You want a delivery confirmation you can save, not just a "sent" toast that disappears. For medical, legal, and tax faxes this is the whole point.
The right compliance tier
"HIPAA-compliant" often means "on our top plan." If you handle PHI, confirm the specific tier that includes a signed BAA before you subscribe.
Pages vs. seats
Personal senders should watch page allowances and overage rates. Teams should care more about seats, shared inboxes, and admin controls.
So which one?
For a single fax off your iPhone, #Fax is the least amount of friction, and free to start settles most one-off situations. For a team that lives in the browser and email, FAX.PLUS is the natural fit - just don’t assume HIPAA below Enterprise. If you send a lot or reach outside North America, eFax’s page limits are hard to beat. And if compliance is the reason you’re shopping at all, iFax gets you a HIPAA-ready plan without an enterprise sales call.
One habit that outlasts whichever app you pick: prices, page caps, and compliance terms change, so open the plan page before you pay and confirm the number that matters to you is on the tier you’re actually buying.
