Best Fax App for iPhone in 2026

At a glance: the 5 best iPhone fax apps in 2026

The table below summarises each app on the three things most senders care about: price, HIPAA compliance, and whether you need an account.

Pricing reflects each vendor’s published retail tiers as of April 2026. Promotional offers may lower the entry price.

1. Faxend — Best overall for most iPhone users

Best for: People who fax occasionally, healthcare professionals, and anyone who wants to avoid subscriptions.

Faxend is the only mainstream app that lets you send a single fax without signing up for a monthly plan. You pay $2.99 for up to five pages, your credits are valid for 30 days, and there is nothing to cancel.

The iPhone app mirrors the web dashboard one-for-one. Upload a PDF or scan a page with your camera, enter the destination number, and hit send. A delivery receipt reaches you within a minute.

For higher-volume senders, Faxend offers two subscriptions. Standard is $9.99 per month for 20 pages and adds fax history plus searchable archives. Pro is $19.99 per month for unlimited pages and priority delivery.

Pros

• Pay per fax, no subscription needed
• HIPAA-ready across every tier
• Same experience on iPhone and web
• End-to-end AES-256 encryption
• 30-day transmission archive on paid plans

Cons

• New to the market compared with eFax
• Team workspaces are on the roadmap, not yet shipped

Faxend's biggest advantage is flexible pricing. If you fax twice a year, you still pay twice a year. The ad-free interface and minimal permissions on iOS also make Faxend a favourite for privacy-conscious users.

2. eFax — Best for enterprise and legal workflows

Best for: Law firms, large clinics, and organisations that need a dedicated fax number with corporate billing.

eFax is the veteran in this list. Launched in 1995, it powers fax numbers for millions of professional accounts. Its iPhone app is reliable but built around the assumption you will use the service daily.

The Plus tier at $19.99 per month gives you a dedicated number, 150 inbound and 150 outbound pages, and core integrations. Pro at $23.99 per month adds HIPAA compliance, Business Associate Agreements, and larger page allowances.

Pros

• Long-standing reputation with enterprise buyers
• Dedicated fax number included
• Integrations with Gmail, Outlook, Google Drive
• Large monthly page quotas

Cons

• Expensive for light usage
• Cancellation fee on annual plans
• HIPAA requires the higher Pro tier

If you fax every weekday and need the eDiscovery features bundled with Pro, eFax remains a defensible choice. For occasional senders, the $20+ monthly commitment is hard to justify.

3. iFax — Best for small teams and shared inboxes

Best for: Agencies and small clinics that want shared inboxes and team workflow tools.

iFax has carved a niche with its collaborative features. Shared folders, comment threads on faxes, and role-based permissions make it easy to run a two-to-ten person team from the same account.

Basic at $8.33 per month per user is priced for individuals. The Plus and Business tiers unlock team features. HIPAA compliance sits on the Business plan at roughly $25 per user per month.

Pros

• Strong collaboration tools
• Cleaner interface than older competitors
• OCR search across past faxes

Cons

• Per-seat pricing adds up quickly
• HIPAA only on the top plan
• No pay-per-fax option

iFax is a strong pick when the app is a daily workhorse for a small team. Solo users often find Faxend and FAX.PLUS more cost-efficient for the same feature set minus the team layer.

4. FAX.PLUS — Best for international senders

Best for: Businesses that send faxes abroad, especially to Europe and Asia.

FAX.PLUS, operated by Alohi, specialises in international coverage. It delivers to more than 180 countries and supports local virtual numbers in dozens of regions. New accounts receive 10 free pages to try the service.

Basic plans start at $6.99 per month. HIPAA is gated to the Enterprise tier. Unlike Faxend, casual users cannot send without at least registering an account and accepting a trial-to-paid conversion.

Pros

• Excellent international coverage
• 10 free pages for new users
• Clean web dashboard

Cons

• HIPAA limited to Enterprise
• Account required even for trial
• Occasional delivery delays reported on regional routes

FAX.PLUS is a pragmatic choice when you routinely send documents across borders. For domestic US use, Faxend delivers the same reliability at a lower per-fax cost.

5. MyFax — Best extended free trial

Best for: Users who want to test a service thoroughly before committing.

MyFax offers a 30-day free trial, the longest in this comparison. Pricing starts at $10 per month after the trial for 100 inbound and 100 outbound pages. It is owned by J2 Global, the same parent company as eFax.

Pros

• Generous 30-day trial
• Reasonable monthly pricing
• Dedicated inbound number

Cons

• Interface feels dated
• HIPAA BAA only on higher tiers
• Customer support response times have slipped in recent reviews

MyFax is a good staging ground for users who want a month to decide. Past the trial, newer apps like Faxend and iFax tend to win on user experience.

How we tested

We ran the same three test documents through each app in April 2026. Test conditions were held constant across apps to make the comparison fair.

1. Short form. A single-page PDF sent to a US toll-free fax line.
2. Medical record. A five-page PDF with embedded images, sent to a HIPAA-compliant clinic fax.
3. International contract. A twelve-page PDF sent to a fax number in Germany.

Each app was scored on four dimensions:

• Delivery time — measured from tap to confirmation receipt.
• Price per page — normalised against each app’s lowest published plan.
• Security posture — encryption in transit, at rest, and availability of a Business Associate Agreement.
• iOS polish — how natural the app feels on iPhone, including Share Sheet support.

The full scoring rubric is available on request. We are also publishing a separate guide to HIPAA-compliant fax if you want a deeper dive into the compliance angle.

What to look for in an iPhone fax app

Not every fax app is built the same. Use this short checklist before you pay.

1. Pricing that matches your frequency

If you send fewer than five faxes a month, avoid monthly subscriptions. A pay-per-fax plan like Faxend Basic costs less and removes renewal friction. If you fax daily, a 100-page plan amortises below pay-per-fax.

2. HIPAA and encryption

Any fax carrying Protected Health Information must travel over an encrypted channel. Confirm the provider signs a Business Associate Agreement. Avoid services that only offer HIPAA on their highest tier unless your volume justifies it.

3. Delivery proof

A good app returns a timestamped confirmation within a minute of transmission. Look for transmission logs that include recipient number, page count, and status per page.

4. iOS native behaviour

The app should support iOS Share Sheet so you can fax directly from Mail, Files, or scanning apps. Background uploads and Face ID protection on the archive are both signs of a well-built app.

5. No lock-in

Check the cancellation policy. Some legacy providers charge termination fees on annual contracts. Month-to-month billing is the modern default.

Frequently asked questions

Is it legal to send a fax from an iPhone?

Yes. Faxes sent from a mobile app use the same T.38 or G.711 signaling as a traditional machine. Courts, hospitals, and the IRS accept app-based faxes just like physical faxes.

Are iPhone fax apps HIPAA-compliant?

Some are. Faxend, iFax, FAX.PLUS, and eFax each offer HIPAA-ready tiers with encryption in transit and at rest. Always sign a Business Associate Agreement before sending Protected Health Information.

Can I send a fax from iPhone for free?

Most apps offer a free trial or a small number of free pages. Faxend Basic starts at $2.99 for up to 5 pages with no subscription. FAX.PLUS gives 10 free pages to new accounts.

Do I need a phone line to send a fax from iPhone?

No. Fax apps use the internet to connect to a gateway that converts your document into a fax signal. Your iPhone only needs Wi-Fi or cellular data.

How long does it take to send a fax from my iPhone?

A typical single-page fax reaches the recipient in 30 to 60 seconds. Longer documents and international destinations can take a few minutes.

Can I also receive faxes on my iPhone?

Yes, if the app provides a dedicated fax number. Faxend Pro, eFax, and iFax all support inbound fax delivered to your inbox as PDF. See our upcoming guide on how to receive faxes online for setup steps.
